WARNING

Improper use of the Wingman Advanced system can result in a collision causing property damage, serious injuries, or death.

The driver is always responsible for the control and safe operation of the vehicle at all times. The Bendix Wingman Advanced system does not replace the need for a skilled, alert professional driver, reacting appropriately and in a timely manner, and using safe driving practices.

DESCRIPTION

The Wingman Advanced system is an integrated combination of three features:

• Adaptive cruise control with braking,

• Alerts (three types of alerts), and

• Collision mitigation technology.

PART ONE: ADAPTIVE CRUISE CONTROL WITH BRAKING

The adaptive cruise control with braking feature is an additional upgrade of ordinary cruise control. When using cruise control, the Wingman Advanced system will maintain the set speed, and also will intervene, as needed, to help maintain a set following distance behind a detected forward vehicle.

Using a radar (with a range of approximately 500 feet) mounted to the front of the vehicle, the Wingman Advanced system reacts to detected forward vehicles in the same lane, traveling in the same direction. See Figure 1.

The adaptive cruise control with braking feature is designed to help the driver maintain a set following distance between

his vehicle and a detected forward vehicle when cruise control is set. See the gray "Radar Beam" area in Figure 2.

RADAR BEAM

The STRIPED area approximates the zone where the collision mitigation feature is ready to intervene with up to two-thirds of the of vehicle’s braking capacity, if needed, as long as the vehicle is traveling above 15 mph.

Once cruise control is set and the system is maintaining a set following distance between you and the vehicle in front:

imposed by factory-set road speed governors, etc. are fully supported by the Wingman Advanced system.

If the vehicle in front of you slows down below the cruise control’s set speed, the Bendix

Wingman® Advanced

™

system will intervene and, as necessary, in this order:

(a) reduce the engine throttle, then

(b) apply the engine retarder, then

in an attempt to maintain the set following distance behind the vehicle ahead. NOTE: If during the intervention, it is necessary to apply the foundation brakes, the vehicle will not automatically resume the cruise control set speed.

If the vehicle ahead slows below the cruise control’s set speed, but then accelerates away, and the Wingman

Advanced system did not need to use the foundation

brakes, the system will automatically accelerate back to the original cruise control set speed, and again maintain a set following distance behind any detected forward vehicles.

Because the Wingman Advanced system operates along with normal cruise control, all the typical features built into cruise control work as usual. For example, limits

P ART TWO: ALERTS

Bendix Wingman Advanced also assists by giving audible and visual alerts, whether or not cruise control is on. See Pages 8-10 for more information on the three types of alerts the driver may hear and/or see displayed.

PART THREE: COLLISION MITIGATION TECHNOLOGY

See the striped area in Figure 1. Wingman Advanced’s

collision mitigation technology is designed to be ready to react to the presence of moving vehicles in front of your vehicle (whether or not cruise control is set). Collision mitigation interventions can be up to two-thirds of the vehicle’s braking capacity. The system provides the driver with an alert before an intervention occurs. The driver must immediately act to potentially avoid, or lessen the severity of, a collision.

1.01 IMPORTANT SAFETY INFORMATION

This vehicle's cruise control must be used only in the same conditions that are normally recommended for ordinary cruise control.

Vehicle manufacturers may use alerts, messages, and dash arrangements that vary from the examples shown here. Consult the vehicle operator’s manual for applicable details regarding use and operation.

WHEN NOT TO USE WINGMAN ADV ANCED ADAPTIVE CRUISE CONTROL WITH BRAKING

The adaptive cruise control and braking feature in Wingman Advanced is automatically ready when normal cruise control is set.

This vehicle’s cruise control must be used only in the same conditions that are normally recommended for ordinary cruise control. As noted below , there are certain situations when cruise control should NOT be used.

• Inclement Weather – Do not use cruise

control in rain, snow, fog, ice or other severe weather conditions that may affect the performance of the Wingman Advanced system.

• Dense Trafﬁ c – Do not use cruise control

in heavy trafﬁ c.

• Sharp Curves and Winding Roads –

Do not use cruise control when traveling sharply curved or winding roadways. CAUTION: Road curvature may impact the radar’s ability to track vehicles ahead in the same lane.

• Entrance or Exit Ramps – Do not use

cruise control when entering or exiting roadways.

• Downhill Grades – Do not use cruise

control on downhill grades.

• Construction Zones – Do not use cruise

control in construction zones.

• Off-Road – Do not use cruise control in

off-road conditions.

• Smaller Forward Vehicles – Smaller

vehicles, such as motorcycles, may be

difﬁ cult for the radar to identify. It is the

driver’s responsibility to be aware of these types of vehicles and to slow down if necessary.

Visit www.bendix.com for more information and any updates to these limitations and restrictions.

AUTOMATIC FOUNDATION BRAKE APPLICA TIONS

The vehicle automatically manages foundation brake priorities among the various vehicle systems that use the foundation brakes, such as Bendix

Wingman® Advanced

™

system, Bendix®ESP® Electronic Stability Program, Bendix®ATC (Automatic Traction Control) and Bendix ABS (Antilock Braking System).

NOTE: Cruise control will automatically cancel whenever the Wingman Advanced system applies the foundation brakes. You can verify that your cruise control is disengaged by observing that the cruise-enabled icon is no longer illuminated. You must resume or set cruise control in order to regain normal cruise control functionality and to reengage the adaptive cruise control with braking feature of the Wingman Advanced system.

Additional information, and complete troubleshooting procedures for the Bendix ESP stability system, can be found in the Bendix Service Data Sheet SD-13-4869.

1.02 SYSTEM COMPONENTS

The radar sensor (or radar) used in the Wingman Advanced unit is located at the front of the vehicle – either on the

bumper or just behind it on a cross-member. See Figure 3.

Also see the Indications and Alerts section of this manual on page 16 for more detailed information about the alerts.

NOTE: For some integrated systems, the volume level of the alerts is not adjustable, nor can they be switched off.

1.03 ACTIVATING THE BENDIX

WINGMAN® ADV ANCED™ SYSTEM

To have the Wingman Advanced cruise control with braking features of the Wingman Advanced system (engine dethrottle/retard, foundation brake interventions) the vehicle’s

regular cruise control must be switched on. See Figure 5

for examples of switches that may be used.

When the vehicle reaches the desired cruise speed, the driver presses the cruise control set switch to activate the system. The Wingman Advanced system will then engage and help the driver maintain a set following distance behind the vehicle traveling in front.

Once the cruise control speed is set, a cruise-enabled icon (or similar) will illuminate on the instrument panel. If the cruise-enabled or set (or similar) icon does not illuminate, the Wingman Advanced system is not functioning normally. Refer to the vehicle operator’s manual to double-check the location of the icon, and for further troubleshooting information.

FIGURE 3 - COMPONENT: RADAR SENSOR

The radar sensor is pre-aligned at the factory and no adjustment should be needed. If the radar sensor becomes misaligned (or a diagnostic trouble code is issued), either a message – or light on the dash, depending on the vehicle – lets the driver know that service is needed.

The Wingman Advanced system is either fully integrated into the vehicle dashboard, or uses the Bendix

Driver

Interface Unit (DIU). See Figure 4.

FIGURE 4 - BENDIX DRIVER INTERFACE UNIT (DIU)

Although the system functions the same, how the alerts are displayed to the driver can be different. Where a DIU (Driver Interface Unit) is used, all visual, text, and audible indicators and alerts will be provided by the DIU. The DIU

allows the volume to be adjusted. See Appendix B.

The driver can switch off the Wingman Advanced system manually by either stepping on the brake pedal or switching off the cruise control.

FIGURE 5 - EXAMPLES OF CRUISE CONTROL SWITCHES

IMPORTANT NOTE: Cruise control will automatically cancel whenever Wingman Advanced applies the foundation brakes.

1.05 HOW A DRIVER INTERACTS WITH BENDIX® WINGMAN® ADV ANCED

™

Table 2 illustrates how the Wingman Advanced system will respond to various actions a driver may take when using Wingman Advanced system on the road.

How a Driver Interacts with Bendix®Wingman® Advanced™ (1.05)

Action Reaction of Wingman Advanced

If the driver does this: Expect the Wingman Advanced system to do this:

Steps on the brake. (During a collision mitigation event)

The driver is always in control and is able to apply full braking power.

Steps aggressively on the accelerator. (During a collision mitigation event.)

Steps on the brake. (When in cruise.)

Steps on the accelerator. (When in cruise.)

Switches on the cruise control.

Switches off the cruise control.

Sets the cruise control speed.

Covers or blocks the radar.

Uses normal cruise control “+/-” switch.

The driver is always in control. His/her actions override any Wingman Advanced system actions. Note: If cruise control is engaged, it will be overridden until the accelerator is released; then cruise control will resume the original set speed automatically.

Cruise control will be cancelled.

Cruise control will be overridden until the accelerator is released; then cruise control will resume the original set speed automatically.

Nothing. The adaptive cruise control with braking feature will not engage until the driver sets the cruise control speed.

The adaptive cruise control with braking feature will turn off; the collision mitigation feature remains active and ready to intervene. The driver will continue to hear all alerts as needed.

The adaptive cruise control with braking feature is automatically activated. Your vehicle maintains a set speed and following distance behind the vehicle ahead.

The Wingman Advanced system performance will be diminished or even disabled and a Diagnostic Trouble Code (DTC) will be set. A blockage will also affect engine cruise control availability.

Vehicle speed increased (+) or reduced (-) to achieve the new set speed while actively maintaining following distance with the vehicle ahead, if one is present within 500 feet.

NOTE: The system responses above are typical, but may vary from the descriptions shown here by vehicle manufacturer, or earlier versions of the Wingman Advanced system. These are examples of driver actions and typical Wingman Advanced system responses, however this chart does not attempt to cover all possible situations.

TABLE 2 - HOW A DRIVER INTERACTS WITH BENDIX® WINGMAN® ADVANCED

Page 8

THE FORWARD VEHICLE DETECTED ICON

When cruise control is switched on and set and a vehicle ahead of you is detected by the radar, the detected forward vehicle icon, or similar will illuminate on the vehicle dashboard.

This is an indication to the driver that the Wingman

Advanced system is actively managing the distance between your vehicle and the vehicle ahead, and may intervene automatically, if needed.

See Figure 6 for examples.

FIGURE 6 - FORWARD VEHICLE DETECTED ICONS

ADJUSTING THE CRUISE CONTROL SPEED

Use the switch(es) provided by the vehicle manufacturer to set your cruise control speed. When adjusted, your set speed will typically be indicated on the vehicle dash, message center, or speedometer.

1.06 FOLLOWING DISTANCE

Following distance refers to the time gap, measured in seconds, between your vehicle and the vehicle ahead. The actual physical distance between the two will vary based on the speeds of both vehicles; however, the set gap will remain the same for all set cruise speeds.

FOLLOWING DISTANCE ADJUSTMENT SWITCH

This optional Wingman Advanced feature, allows the driver to adjust the following distance or time gap. The availability of this feature is determined by the vehicle manufacturer. The switch has an increase or decrease function. Pressing increase (+) will provide a larger following distance, measured in seconds. Pressing decrease (-) will provide a shorter following distance.

1.07 WINGMAN ADVANCED COLLISION MITIGATION FEATURE OPERATION

Whenever your vehicle is traveling at above 15 mph, the Wingman Advanced collision mitigation feature is ready to intervene, if needed. It does not require cruise control to be set. The collision mitigation feature of Wingman Advanced will alert you automatically and apply up to two-thirds of the vehicle’s braking capacity, if a collision with the detected forward vehicle is likely to occur. You, the driver, must immediately act to potentially avoid, or lessen the severity of, a collision.

Collision mitigation is ready to intervene as long as no DTCs are active in either the brake system, Wingman Advanced system, or any other contributing vehicle system.

AUTOMATIC FOUNDATION BRAKE APPLICA TIONS

The vehicle automatically manages foundation braking priorities among the various vehicle systems that use the foundation brakes, such as Wingman Advanced, Bendix® ESP® (Electronic Stability Program), Bendix®ATC (Automatic Traction Control) and the Bendix® ABS (Antilock Braking System).

1.08 ALERTS AND WARNINGS

The Bendix differently compared to other cruise control/forward collision

warning systems. It is important for YOU to fully understand

the system’s features, especially the driver alerts and warnings.

Three important warnings provided by the Wingman Advanced system are the Following Distance Alert (FDA), Impact Alert (IA), and Stationary Object Alert (SOA). The driver will be alerted by any of the three warnings, whether or not the cruise control is activated.

See Appendix B, Sections 3.0-5.0, for more information about how DIUs communicate alerts.

WARNING: Any audible and/or visual alert by the

system means that your vehicle is too close to the vehicle ahead and the driver must immediately act to potentially avoid, or lessen the severity of, a collision.

Wingman® Advanced

™

system operates

Page 9

IMP ACT ALERT (IA)

FOLLOWING DISTANCE ALERT (FDA)

The Impact Alert is the most severe warning issued by the Wingman Advanced system. This alert indicates that a collision with the detected forward vehicle is likely and the driver must immediately act to potentially avoid, or lessen the severity of, a collision.

The Impact Alert is ready to alert the driver whenever the vehicle is moving above 15 mph.

When activated, the IA will sound and a visual message/ icon typically appears on the dash screen or Bendix

Driver

Interface Unit (DIU) display. The actual sound/display method varies by vehicle manufacturer.

NOTE: The Impact Alert is typically accompanied by automatic brake interventions. The Wingman Advanced system will apply up to two-thirds of your vehicle’s braking capacity. The driver must apply additional braking, when necessary, to maintain a safe distance from the vehicle ahead.

See Figure 7 for an example of an Impact Alert Icon.

The Following Distance Alert (FDA) provides both audible and visual alerts whenever the time between your vehicle and the detected forward vehicle ahead is less than the one and a half (1½) seconds* and decreasing. Once the audible alert is given, the driver should increase the distance between his/her vehicle and the vehicle ahead until the audible alert stops.

The FDA is ready to alert the driver whenever the vehicle is moving

above ﬁ ve (5) mph. If

the following distance continues to decrease, the driver will hear more rapid audible alerts. When the FDA

reaches its highest

level, typically a red LED also illuminates

on the instrument

cluster. The FDA may be accompanied by a visual alert.

FIGURE 9 - DRIVER INTERFACE UNIT (DIU) SHOWING EXAMPLES OF FOLLOWING DISTANCE ALER TS WITH PROGRESSIVELY FASTER AUDIBLE ALERTS.

SEEN ON THE BENDIX

DIU

Above: Examples of other vehicle

manufacturer’s displays.

FIGURE 10 - FOLLOWING DISTANCE ALERT

STATIONARY OBJECT ALERT (SOA)

Stationary Object Alert (SOA) – The Bendix Wingman® Advanced™ system will give up to three (3) seconds alert to the driver when approaching a detected, sizable, metallic (radar-reﬂ ective), stationary object in your lane of travel. This alert indicates that a collision with a stationary object is likely and the driver must immediately act to potentially avoid, or lessen the severity of, a collision.

The SOA is ready to alert the driver whenever the vehicle is moving above ten (10) mph.

Page 10

The driver should be especially careful when approaching certain types of vehicles or objects. The Wingman Advanced radar may not be able to detect vehicles and objects with limited metal surfaces (such as recreational vehicles, horse-drawn buggies, motorcycles, logging trailers, etc.).

NOTE: Entering a curve may reduce the alert time to less than three (3) seconds.

Advanced system foundation brake applications for at least 20 minutes.

• If the system does not detect a driver intervention within 15 seconds after the brake overuse alert sounds, it will shut itself off and set a Diagnostic Trouble Code (DTC). The driver will continue to receive alerts, but ALL Wingman Advanced interventions (de-throttling, engine retarder or brake applications) will be disabled until the next ignition cycle.

Note: In all cases, the driver still has the ability to apply the foundation brakes if necessary. The driver should take care since overheated brakes may reduce the vehicle’s braking capability.

(See Appendix B7.0).

FIGURE 11 - STATIONARY OBJECT ALERT DISPLAYED

BRAKE OVERUSE ALERT

The Bendix® Wingman® Advanced™ system provides a warning when the system is intervening and using the foundation brakes excessively. Overuse of the foundation brakes can lead to the brakes overheating and a potential loss of braking performance caused by brake fade. Using cruise control on downhill runs will

cause this alert to be activated.

Approach grades as you would normally , with the appropriate gear selected and at a safe speed. Cruise control should NOT be used on downhill grades.

When the system detects brake overuse, depending on the vehicle manufacturer, a text message will be displayed on the dashboard and an audible alert will be activated. The driver should intervene immediately.

FIGURE 12 - BRAKE OVERUSE WARNING

• Once the brake overuse alert is activated, certain

driver interventions that cancel cruise control – like stepping on the brake pedal or switching off cruise – will discontinue the alert. Following an overuse alert, the driver should not reset cruise control for at least 20 minutes. This gives the brakes time to cool down. If the driver chooses to reset cruise control during that 20 minute period, Wingman Advanced interventions will be limited to de-throttling and engine retarder only. The system will automatically disable all Wingman

1.09 WINGMAN ADVANCED DIAGNOSTIC TROUBLE CODES

The Wingman Advanced system is monitored and if any

malfunction is detected, a Diagnostic Trouble Code (DTC) will be set and the driver will be alerted. The exact alert given depends on the vehicle manufacturer: refer to your vehicle operator’s manual and Sections 3 and 4.

1.10 RADAR SENSOR INTERCHANGEABILITY

Many variables must be considered when determining whether or not the radar sensor can be relocated from one vehicle to another vehicle. They include, but are not limited to, the version of the Bendix®ESP® stability system used on the vehicle, the instrument cluster, the vehicle ECU, the engine and the transmission. at 1-800-AIR-BRAKE to determine if this is a viable option.

WARNING:

without contacting Bendix ﬁ rst!

Do not interchange radar sensors

Contact the Bendix Tech Team

1.11 ALERT VOLUME

For Wingman Advanced systems installed on vehicles with alerts that come directly through the instrument cluster, audible alert levels are pre-set at the factory and can not be turned off, nor can the volume be adjusted. However, where the Bendix volume adjustment is permitted.

Driver Interface Unit (DIU) is used,

1.12 POTENTIAL FALSE WARNINGS

In certain unusual trafﬁ c or roadway conditions, Wingman

Advanced may issue a false alert. While eliminating all false alerts is not possible, if false alerts occur too frequently (more than twice a day), this may indicate sensor misalignment. Service the system at the earliest opportunity.

Drivers should take into account the road conditions, and any other factors they are encountering, as they choose how to react to any alerts they receive from the Wingman Advanced system.

2.1 GENERAL SAFETY GUIDELINES WARNING! PLEASE READ AND

FOLLOW THESE INSTRUCTIONS TO AVOID PERSONAL INJURY OR DEATH:

When working on or around a vehicle, the following general precautions should be observed at all times.

1. Park the vehicle on a level surface, apply the parking brakes, and always block the wheels. Always wear safety glasses.

2. Stop the engine and remove ignition key when working under or around the vehicle. When working in the engine compartment, the engine should be shut off and the ignition key should be removed. Where circumstances require that the engine be in operation, EXTREME CAUTION should be used to prevent personal injury resulting from contact with moving, rotating, leaking, heated or electrically charged components.

3. Do not attempt to install, remove, disassemble or assemble a component until you have read and thoroughly understand the recommended procedures. Use only the proper tools and observe all precautions pertaining to use of those tools.

4. If the work is being performed on the vehicle’s air brake system, or any auxiliary pressurized air systems, make certain to drain the air pressure from all reservoirs before beginning ANY work on the vehicle. If the vehicle is equipped with a Bendix a dryer reservoir module, be sure to drain the purge reservoir.

5. Following the vehicle manufacturer’s recommended procedures, deactivate the electrical system in a manner that safely removes all electrical power from the vehicle.

6. Never exceed manufacturer’s recommended pressures.

7. Never connect or disconnect a hose or line containing pressure; it may whip. Never remove a component or plug unless you are certain all system pressure has been depleted.

8. Use only genuine Bendix® brand replacement parts, components and kits. Replacement hardware, tubing,

hose, ﬁ ttings, etc. must be of equivalent size, type

and strength as original equipment and be designed

speciﬁ cally for such applications and systems.

9. Components with stripped threads or damaged parts should be replaced rather than repaired. Do not attempt repairs requiring machining or welding unless

speciﬁ cally stated and approved by the vehicle and

component manufacturer.

10. Prior to returning the vehicle to service, make certain all components and systems are restored to their proper operating condition.

11. For vehicles with Automatic Traction Control (ATC), the ATC function must be disabled (ATC indicator lamp should be ON) prior to performing any vehicle maintenance where one or more wheels on a drive axle are lifted off the ground and moving.

2.2 EQUIPMENT MAINTENANCE: BRAKE SYSTEM AND ABS FUNCTIONALITY

Importance of Antilock Braking System (ABS)

Maintenance – Optimal Bendix® Wingman® Advanced

system braking requires a properly maintained ABS system, without any active ABS Diagnostic Trouble Codes (DTCs).

Have active DTCs repaired by a qualiﬁ ed technician. Any

ABS DTCs will cause Wingman Advanced to deactivate.

Importance of Brake Maintenance – Optimal

Wingman Advanced braking requires properly maintained foundation brakes (drum, wide-drum, or air disc) which meet appropriate safety standards and regulations. Brake performance also requires that the vehicle be equipped with

properly sized and inﬂ ated tires, with a safe tread depth.

System Problems – If a problem with the Wingman

Advanced system is detected, depending on the vehicle manufacturer, typically there will be a message on the dashboard display. Depending on the type of problem detected, the system will determine if the vehicle may continue normal cruise control functions (without the

beneﬁ ts of Wingman Advanced), or whether all cruise

control functions should be disabled until service is performed. The system should be serviced as soon as possible to restore full Wingman Advanced functionality.

™

2.3 SYSTEM PREVENTIVE MAINTENANCE

The Wingman Advanced system is relatively maintenance free. The key items to keep the system functioning properly include:

1. Keep the radar lens clean and free of obstructions.

2. Inspect for any damage to the bumper or the Wingman Advanced cover, bracket or radar to ensure that the

alignment has not been compromised. Never use the

radar unit as a step.

3. Periodically check the radar alignment.

4. Perform appropriate inspections of the braking system as required by the manufacturer to ensure brakes are in proper working order.

5. Ensure that the tires are properly inﬂ ated and that

adequate tread is present.

Radar Inspection – The driver should inspect the

radar and mounting bracket regularly and remove any mud, snow, ice build-up, or other obstructions. The installation of aftermarket deer guards is not recommended, and could impair the operation of the radar.

Radar Damage / Misalignment / Tampering - In

cases where the bumper and/or radar have sustained any damage, are misaligned, or if you suspect that the radar has been tampered with, do not use the cruise control until the vehicle has been repaired and the radar re-aligned. In addition, an indicator on the dash typically will illuminate if the system detects any of these conditions. Consult your vehicle’s operator’s manual or contact Bendix for more information.

NOTE: Any vehicle trouble code that disables vehicle cruise control will also cause a diagnostic trouble code in Wingman Advanced.

This section introduces three initial steps to accurately troubleshoot the Bendix

We recommend reading this introductory section, as well as the Troubleshooting/Diagnostics Section (4.0), before performing any troubleshooting.

When diagnosing the Wingman Advanced system, in many

cases Bendix

ACom®Diagnostics software (version 6.3 or higher) will be required. This software is available as a free download from www.bendix.com.

3.1 TROUBLESHOOTING BASICS

Troubleshooting Basics (3.1)

Questions Next Steps

What color is the radar sensor?

The Wingman Advanced system has a black “eyeball” radar sensor (See Section 1.02). If the radar sensor is ﬂ at-fronted, or is yellow, it is not a

Wingman Advanced radar sensor.

Wingman® Advanced

™

system.

Have the driver run the Power-Up Self-Test.

Does the driver hear a

long warning beep?

Power-Up Self-T est

This is a self diagnostic check, to determine if the system operation is normal.

Park the vehicle. Power off.

Put the key into the ignition, and turn to the “ignition power” position.

Toggle the cruise control switch at least once, and leave it in the “on” position.

Start the vehicle, but do not drive away.

Note that if the cruise control is in the “off” position, or if the vehicle is moving, this test will not run.

The self-test will start after 15 seconds, and takes approximately ﬁ ve

(5) seconds to complete. (Note that other vehicle system self-tests, e.g. the ABS “chuff” test, may run during the initial 15 seconds after ignition “on.”) As the Wingman Advanced self-test runs, the driver should hear a short set of beeps. The test checks the engine, transmission, and brake systems to make sure they are communicating. In addition, depending

on the vehicle, the test may brieﬂ y display a distance alert message

and/or cause the Forward Vehicle Detected icon in the instrument cluster to illuminate; this is normal.

If no problem is found and the test is passed, no additional beeps/lamps will be displayed nor will a trouble code be set.

If the system has found an issue that will prevent it from functioning properly,

a long warning beep will sound to alert the driver, and a Diagnostic Trouble

Code (DTC) will be logged in the syst em (typi c a l ly with a status in dicator/dash

icon illuminated). For descriptions of all DTCs, see Section 4.3: Diagnostic

Trouble Codes.

Have the driver describe the system behavior that they believe shows it is not working properly.

TABLE 3 - TROUBLESHOOTING BASICS

When diagnosing the system, especially in cases where there are no

diagnostic trouble codes logged, ﬁ nd out which part of the system behavior appears to be operating improperly. See Section 3.2: Narrowing Down the

Problem.

Page 14

3.2 NARROWING DOWN THE PROBLEM

Use the questions found in Table 3.2 below to help assess if the Bendix

Wingman® Advanced

correctly. Be sure to have a thorough understanding of the system’s normal behavior; this will reduce the troubleshooting

time. The table provides a guide to basic troubleshooting questions and possible corrective actions. Items in Italics

cross-reference to the service procedures in this manual to repair the condition described.

If Bendix Tech Team assistance is needed, prior to calling 1-800-AIR-BRAKE, complete the Troubleshooting Checklist

(See Appendix A), to help reduce the time needed to troubleshoot the system.

Narrowing Down the Problem (3.2)

Questions Next Steps Alignment Problems

Is the radar sensor mounting location (bumper or cross member) damaged?

• Does the system seem to lose, or “not hold on to,” the forward vehicle when going around curves? • Does the system seem to warn on vehicles in adjacent lanes? • Are there false alerts when passing other vehicles? • Does the system seem to warn late when another vehicle cuts in front of the truck? • Does the

system seem to not "see" as far as it “used

to”, or warn on many more overhead bridges/ signs than previously? • Does the system seem to be inconsistent when tracking forward vehicles?

Blocked Radar Sensor Issues

Is mud, ice, or snow covering the radar sensor?

Is anything blocking the view of the radar sensor?

Potential False Warnings

Do false alerts seem to happen in construction zones or going under bridges?

Other Questions

Has the system worked properly in the past and is not working correctly now?

Re-align the radar sensor vertically and laterally. Use the following procedures:

• Section 6.07: Check Vertical Alignment and adjust if needed.

• Section 6.09: Check Lateral Alignment and adjust if needed.

• Section 6.02: Check Radar Sensor Mounting – The radar needs a solid

mounting surface in order to hold the alignment. If the bumper or mounting

cross member is damaged, replace it ﬁ rst, then align the radar sensor.

Clean the radar sensor lens immediately. Remove anything blocking the radar sensor then power cycle and read any remaining trouble codes.

Read Section 4.3: Diagnostic Trouble Codes.

If the vehicle's cruise control is set and the radar sensor is blocked by ice, snow, mud, tampering, etc. so that it cannot "see" a forward vehicle, Wingman Advanced will log a diagnostic trouble code (DTC).

After the blockage is removed, the DTC will clear automatically. This process also will set a vehicle cruise control DTC which must be cleared with an ignition key cycle.

Add a visual check of the radar sensor for blockage to the driver’s pre-trip inspection checklist.

Several road scenarios have a tendency to cause false warnings, including construction zones and bridges. Unless these false warnings are frequent, the system is likely reacting normally. The driver should not set the cruise control in construction zones. If driver complaints persist, continue asking questions to more

narrowly deﬁ ne the driving condition presenting the problems. Review proper

operating conditions in the operator's manual.

This is a good indication that something has changed, such as misalignment of the radar sensor. Review questions listed above with the driver to further diagnose the problem.

™

Narrowing Down the Problem (3.2)

Questions Next Steps

Does the mounting bracket look damaged or tampered with?

Did the radar sensor currently on the vehicle come from another vehicle?

With cruise control set, does the system consistently apply the foundation brakes when a forward vehicle slows?

Does a diagnostic trouble code (DTC) seem to occur when driving through the desert or in barren areas (no road signs, trees or vehicles)?

Does the system seem to disengage after an

automatic braking event?

Does cruise control disengage sometimes when the brakes come on and not at other times?

Does the connector or wiring appear damaged?

Does the system generate a diagnostic

trouble code going down a grade, but the code goes away later?

Does the radar sensor have noticeable damage beyond normal discoloration or surface scratches?

TABLE 4 - NARROWING DOWN THE PROBLEM

Other than expected surface scratches or some discoloration over time, there should be no visible damage to the radar sensor bracket assembly. If so, realign the radar sensor vertically and laterally. If radar sensor alignment can not be held in place, the bracket assembly must be replaced. Verify the bumper is not damaged.

• Check the Vertical Alignment (6.07) and adjust if needed.

• Check the Lateral Alignment (6.09) and adjust if needed.

The Radar Sensor Mounting - The radar sensor needs a solid mounting surface in order to hold the alignment. If the bumper or mounting cross member is

damaged, replace it ﬁ rst, then align the radar sensor.

The radar sensor may be incompatible with the new vehicle. Follow Section

1.10: Radar Sensor Interchangeability procedure and check system trouble codes

with Bendix

ACom® Diagnostics software.

Read Section 4.3: Diagnostic Trouble Codes.

This is normal operation. Continue asking the driver questions to diagnose the problem. The radar sensor may be blocked or misaligned. The service technician will need to check trouble codes as well.

• Check the Vertical Alignment (6.07) and adjust if needed.

• Check the Lateral Alignment (6.09) and adjust if needed.

The Radar Sensor Mounting - The radar sensor needs a solid mounting surface in order to hold the alignment. If the bumper or mounting cross member is

damaged, replace it ﬁ rst, then align the radar sensor. Read Section 4.3: Diagnostic Trouble Codes.

In normal operation, the adaptive cruise control with braking feature of Bendix

Wingman® Advanced

™

system may “go dormant” if it hasn’t detected a metallic object after a pre-determined period. This is rare, but most likely to occur when driving in deserts or barren areas. If the system does “go dormant,” Wingman Advanced provides a visible warning to the driver. In addition, the vehicle also will drop out of cruise mode, providing an audible and/or visual warning to the driver as well. The driver must actively re-engage the vehicle’s cruise control. Once the desired cruise speed is set, the adaptive cruise control with braking feature of Wingman Advanced will resume operation. When metallic objects are again detected by the Wingman radar sensor, the trouble code previously recorded in the Wingman system will clear automatically.

This is normal operation. The driver must set or "resume" the cruise control once again to regain the following distance function.

This is normal operation. When traveling with lightly loaded trailers, or “bobtail”, the adaptive cruise control with braking feature of Wingman Advanced may continue to function even after an automatic brake application. No driver input is needed.

Wires can become corroded if the radar sensor is not plugged in properly. Clean the connectors on the wire harness, as well as the radar sensor, and reattach. If wires are chaffed, replace the wire harness. Also, check for trouble codes.

Read Section 4.3: Diagnostic Trouble Codes, and Section 4.8: Troubleshooting Wiring Harnesses.

This is normal operation. The adaptive cruise control with braking feature of Wingman Advanced is not intended to be used on grades. If the system detects this, it will generate a diagnostic trouble code (DTC). Verify there are no diagnostic trouble codes. Proper downgrade driving techniques should be used.

Read Section 4.3: Diagnostic Trouble Codes.

The radar sensor and bracket are very durable. However, if the radar sensor housing or lens is cracked or broken, immediately look for trouble codes via

Bendix

ACom® Diagnostics (version 6.3 or higher) and replace the damaged

radar sensor. Read Section 4.3: Diagnostic Trouble Codes, and Section 6.02: Radar Sensor Mounting.

3.3 OVERVIEW OF POSSIBLE ISSUES

Some customer issues are actually misunderstandings of how the Bendix

Wingman® Advanced

normally. Use Table 5 below to learn the causes of potential issues if Wingman Advanced is not performing correctly. Some issues can be investigated by a visual inspection. Others may cause a diagnostic trouble code (DTC) to be logged:

See Section 4.3: Diagnostic Trouble Codes.

Overview of Possible Issues (3.3)

Issue Description

System familiarity Verify the system functionality. Is it operating normally or not? Drivers who are unfamiliar

with the system may report they don’t like the way it beeps or how it activates the brakes.

Use Section 3.0: Introduction to Troubleshooting, Section 4.3: Diagnostic Trouble Codes and Section 3.1: Questions to Ask the Driver to verify if the system is functioning normally; then

continue.

TABLE 5 - REVIEW OF POSSIBLE ISSUES

Some Diagnostic Trouble Codes (DTCs) indicate a temporary condition and will clear when

that condition is no longer present. If these persist, further investigation is warranted. See Section 3.1: Troubleshooting Basics.

If the performance of the system seems to be erratic or unpredictable, the radar sensor could be misaligned and may need to be aligned both vertically and laterally. If there is a DTC set or if the system does not function, the radar sensor may be severely misaligned

and Wingman Advanced will not operate until this is corrected. See Section 6.01: Vehicle Applications.

Inspect the front of the vehicle. If (a) it has been damaged, or (b) if the vehicle does not track straight, either of these conditions must be repaired before troubleshooting Wingman Advanced.

If the system doesn’t seem to work at all, the radar sensor is probably blocked. A DTC will also be set. Visually inspect it, clear the blockage, turn the ignition on and run through a power cycle.

The Wingman Advanced system will not operate and will set a DTC if any of the following vehicle systems also show a DTC: engine, engine cruise, instrument cluster, Bendix Bendix®ATC, Bendix®ESP, or transmission. These components must be repaired and

cleared of DTCs before troubleshooting Wingman Advanced. (NOTE: Clearing the vehicle

DTCs may be the only step needed to reestablish full Wingman Advanced functionality. See Section 4.4: Clearing Diagnostic Trouble Codes (DTCs)

If the vehicle has been in an accident, it is likely the radar sensor will need to be realigned or replaced. Inspect the radar sensor lens and housing for damage. Radar sensor

discoloration or small scratches may be acceptable. Signiﬁ cant damage will require radar

sensor replacement. Regardless of the exterior condition, check for diagnostic trouble codes

outlined in the Section 4.3: Diagnostic Trouble Codes (DTCs) to determine if radar sensor

replacement is necessary.

Visually inspect the connector and wire harness for corrosion or chafﬁ ng. Refer to Section

4.5: Troubleshooting Diagnostic Trouble Codes: Power Supply of this document for additional

troubleshooting.

If the entire system is non-functional, it may be a J1939 network problem. Follow the

instructions in Section 4.6: Serial Data (J1939) Communications Link.

If the entire system is non-functional, another likely cause may be a lack of power to the radar

sensor. Follow the instructions in Section 4.5: Troubleshooting Diagnostic T rouble Codes: Power

• With the power off, check the resistance across connector pins (60 ohm).

• Check the reverse polarity of J1939 communication circuits at the engine, the ABS and the radar sensor, and at the harness interconnections.

• Check the source of the signal to identify why the signal has an error.

• Check the engine, engine retarder, and ABS for trouble codes using the manufacturer’s diagnostic procedures. Either the engine, engine retarder, or the ABS are the source of the signal. If the signal is in error, then the issue is from the radar sensor or switch input to one of these controllers. The signal with the trouble code may be computed from one or more inputs to these other controllers and may use an additional J1939 signal from another controller. The controller that broadcasts

the signal must be investigated ﬁ rst, but the origin of the

signal could be another component. Some examples are gross vehicle weight and various engine torque signals.

• The controller is recognizing that there are components installed that have part numbers incompatible with the current

system conﬁ guration. (For example, when a technician at-

tempts to install a more recent radar sensor onto a vehicle with an earlier Wingman Advanced or ACB system, or a replacement ECU is programmed incorrectly for this vehicle's system.) Contact the dealer or call the Bendix Tech Team at 1-800-AIR-BRAKE for the correct part number to use, or the reprogramming steps to take for the newer part number to be accepted.

After addressing the possible causes:

• Clear the Bendix Wingman Advanced trouble codes using

the procedure in Section 4.4: Clearing Diagnostic Trouble Codes (DTCs).

• If the error returns, call the Bendix Tech Team for assistance at 1-800-AIR-BRAKE.

Page 23

4.4 CLEARING DIAGNOSTIC TROUBLE CODES (DTCs)

This procedure must be used when troubleshooting the diagnostic trouble codes shown in Table 6.

Clear the Wingman Advanced system Diagnostic Trouble Codes (DTCs) using the Bendix® ACom® service tool. Click the “Clear” button located on the “Read / Clear Fault Codes” screen. Using ignition power only, power off the vehicle for at least 15 seconds. Next start the engine and run it at idle for at least 15 seconds.

Drive the vehicle and, on a test track or suitable section of roadway, engage the cruise control to verify proper operation.

If the error returns, call Bendix at 1-800-AIR-BRAKE for assistance.

4.5 TROUBLESHOOTING DIAGNOSTIC TROUBLE CODES: POWER SUPPLY

IGNITION VOLTAGE TOO LOW

Measure the ignition voltage under load. Ensure that the ignition voltage is greater than 10 VDC (volts DC). Check the vehicle battery and associated components. Inspect for damaged wiring, damaged or corroded connectors and loose connections. Check the condition of the fuse.

IGNITION VOLTAGE TOO HIGH

Measure the ignition voltage. Ensure that ignition voltage is not greater than 16 VDC. Check the vehicle battery and associated components. Inspect for damaged wiring, damaged or corroded connectors and loose connections.

POWER SUPPLY TESTS

1. Take all measurements at the radar sensor harness connector.

2. Place a load (e.g. 1157 stop lamp) across the supply voltage and ground connection. Measure the voltage with the load. The supply voltage on pin 8 to ground should measure between 10 to 16 VDC (volts DC).

3. Check for damaged wiring, damaged or corroded connectors and loose connections.

4. Check the condition of vehicle battery and associated components. Ensure the connection to ground is secure and tight.

5. Using the procedures described by the vehicle manufacturer, check the alternator output for excessive noise.

4.7 ENGINE COMMUNICATIONS (J1939) TEST PROCEDURE

The Wingman Advanced system requires several J1939 messages from the engine ECU to control the engine and retarder torque for distance control and braking. The Wingman Advanced system will set a diagnostic trouble code if one of these messages is not present.

Use the engine manufacturer’s diagnostic test procedures to verify that there are no errors present in the engine that may prevent the Wingman Advanced system from controlling the engine or retarder torque.

4.7.1 J1939 TROUBLESHOOTING PROCEDURE

1. Take all measurements at the harness connector unless otherwise indicated.

CAUTION:

SIDE OF THE CONNECTOR AS THIS WILL DAMAGE THE SEAL AROUND THE WIRE

CAUTION: DO NOT INSERT ANY PROBE INTO THE

PIN ON THE MATING CONNECTOR OF THE RADAR SENSOR THAT IS GREATER THAN 0.62 MM DIAMETER OR SQUARE. THIS WILL DAMAGE THE CONNECTOR PIN

AND REQUIRE REPLACEMENT OF THE HARNESS

2. Check for damaged or reversed J1939 wiring.

If the J1939 HIGH or J1939 LOW wiring circuits are

damaged, such as shorting together, the entire J1939 link will be lost. The problem may be intermittent, enabling the J1939 link to operate normally sometimes. In that event, multiple diagnostic trouble codes will be logged in multiple engine and vehicle controllers.

If the J1939 HIGH and J1939 LOW wiring circuits are

reversed, communication over the entire J1939 link will not be lost. Only those devices that are outside of the problem point from other devices will not receive, or be able to transmit, data messages.

3. Check for corroded or damaged wiring connector problems such as opens or shorts to voltage or ground.

DO NOT INSERT PROBES INTO THE BACK

If the connector terminals are corroded, this may be

an indication of water intrusion into the wiring system

and possibly into the radar sensor. Replacement of the entire harness is recommended. If the terminals of the radar sensor are corroded, replacement of the radar sensor is recommended.

4. Check for other J1939 devices which may be inhibiting J1939 communication. The service technician should consult the vehicle manufacturer’s procedures for other J1939 troubleshooting procedures. The device’s power should be removed and measurements made at the ECU pins for shorts to ground and power pins and resistance between the J1939 HIGH or J1939 LOW input circuits.

5. Unplug the radar sensor. With the ignition switch off, measure the resistance (ohms) using a multimeter between harness pins 2 and 3. The reading should be approximately 60 ohms. If it is not, the vehicle wiring should be investigated using procedures described by the manufacturer.

6. Unplug the radar sensor. With the ignition switch off, using a multimeter, measure the resistance in ohms, between harness pins 2 and ground. The measurement should indicate an open circuit or very high resistance. If this is not the case, the vehicle wiring should be investigated using procedures described by the manufacturer.

7. Unplug the radar sensor. With the ignition switch off, using a multimeter, measure the resistance in ohms, between harness pins 3 and ground. The measurement should indicate an open circuit or very high resistance. If this is not the case, the vehicle wiring should be investigated using procedures described by the manufacturer.

4.8 TROUBLESHOOTING

WIRING HARNESSES

All wire harness connectors must be properly seated to maintain environmental seals. Push the mating connector until it seals with a click. When replacing an Advanced radar sensor, check that the wire harness connector is free of corrosion before plugging into a new radar sensor. Check for corroded or damaged wiring connector problems such as opens or shorts to voltage or ground.

If the connector terminals are corroded, this may be an indication of water intrusion into the wiring system and possibly into the radar sensor. Replacement of the entire harness is recommended. If the terminals of the radar sensor are corroded, replacement of radar sensor is recommended.

6.01 VEHICLE APPLICATIONS

The radar sensor can be mounted and installed only on vehicles that have Wingman Advanced already installed.

At this time Wingman Advanced can not be retroﬁ tted onto

vehicles, even if that vehicle is equipped with the Bendix ESP®stability system.

6.02 RADAR SENSOR MOUNTING

When mounting a radar sensor, the wire harness connector should always point down. The radar sensor assembly is mounted to the front of the vehicle using an adjustable bracket. This adjustable bracket allows for the radar sensor

to be properly aimed laterally and vertically to maximize Wingman Advanced system performance.

The assembly should always be mounted in the original OEM location. If this location is not in the center of the vehicle, the mounting offset will need to be programmed through Bendix

6.09: Check Lateral Alignment.

For proper operation of your Wingman Advanced system, adhere to the following guidelines:

• The radar sensor assembly should be rigidly installed on the vehicle following all OEM recommended torque

speciﬁ cations.

• The radar sensor assembly should be installed in the original OEM designated location.

• The radar sensor cover should always be installed. This helps protect components such as the connector and wiring harness from road debris.

• The radar sensor assembly must be oriented so that the

electrical connector points down. Mounting the radar

upside down will impair performance signiﬁ cantly.

• The radar’s ﬁ eld of view must NOT have interference

from any other vehicle components such as bumpers, cow-catcher bumpers, engine blankets, seasonal decorations, or any other commonly mounted front-ofvehicle components.

NOTE: If original OEM installation was behind a translucent panel, this panel must be reinstalled. Check the panel for damage or scratches that may impact the performance of

Advanced. Replace the panel, if necessary , with an original OEM supplied panel. Do not paint over the panel.

6.04 RADAR SENSOR ALIGNMENT

Accurate vertical and lateral alignment of the radar sensor is critical for proper operation of Bendix

Advanced

™

. Improper alignment will cause false warnings, missed warnings and a diagnostic trouble code in the system.

The radar sensor is mounted to the front of the vehicle using an adjustable bracket. Use the following procedures to align the radar sensor in its adjustable bracket:

Wingman

6.07.2 If the vehicle has an air suspension system, charge the system and set it to “level” prior to carrying out an

radar sensor check or alignment procedure. If the system is not charged, the vertical alignment will be off and the Wingman Advanced system will not perform correctly.

6.07.3 For an accurate check (and adjustment, if necessary) of the vertical alignment, the vehicle needs to be

parked on a ﬂ at, level surface.

NOTE: If the service technician is unable to park the vehicle on a level ﬂ oor, a digital inclinometer must be used to align the sensor vertically.

6.07.4. Position the alignment tool over the sensor so that it straddles the sensor. Attach the alignment tool to the bracket/sensor assembly using its magnet attachments. Use the Lateral Alignment level to make sure that the alignment tool is approximately horizontal width-wise. See Figures 27 and 28.

Follow the manufacturer’s instructions (typically digital inclinometers have a “SET” button for this purpose).

Check the alignment with the alignment tool in position

so that it straddles the radar sensor. Verify that the radar is aligned downward, towards the road surface in front of the vehicle, by -1.3° (± 0.8°), when

measured by an inclinometer set to zero on the vehicle’s frame. If the sensor is not aligned correctly, follow the instructions in section 6.08.

when measured by an inclinometer set to zero on the vehicle’s frame.

Where the bubble-level may be used, verify that the

bubble just touches the line nearest the vehicle. This shows that an incline of approximately one half of a

degree downward has been set. See Figure 31.

FIGURE 32 - VERTICAL ADJUSTMENT (NOTE THIS IMAGE DOES NOT SHOW THE ALIGNMENT TOOL INSTALLED)

Page 32

1. Be sure the vehicle is prepared as shown in Sections

6.07.1-3.

2. With the Bendix alignment tool still in place, loosen the four vertical position screws. DO NOT remove these

screws. See Figure 31. During the adjustment, turn the

vertical alignment screw clockwise or counterclockwise depending on the vertical direction (up or down) needed. Clockwise aligns the radar sensor up and counterclockwise moves the radar sensor down.

3. Where the original tool is being used: (kits K041451

or K041227)

In cases where a digital inclinometer is not being used,

the adjustment should be made until the bubble is just

touching the line closest to the vehicle (See Figure 31.)

4. Where a digital inclinometer is being used:

Adjust the vertical adjustment screw until the digital

inclinometer shows that the radar is aligned downward, towards the road surface in front of the vehicle, by -1.3° (± 0.8°), when measured by an inclinometer set to zero on the vehicle’s frame. (See Figure 29.)

5. Re-tighten the four vertical position screws to hold desired alignment in place.

6. Re-check the vertical alignment after tightening the four vertical position screws.

Note: The alignment process shown here is for Bendix alignment brackets. For other brackets, similar alignment steps will be needed; consult the vehicle manual for full instructions.

5. Using a ruler or tape measure, measure the distance from a symmetrical vehicle point (such as the tow hooks) to the laser light line. Record this measurement.

See Figure 35. NOTE: The technician must be extremely careful

during the laser positioning process to double-check the values measured on each side of the truck. Be sure to check back and forth for each side of the radar sensor several times to ensure accuracy.

6. Repeat the same process for the opposite side and measure the reference distance to the laser line. For tool K042452, the blue laser level is rotated 180 degrees, and for tool K065284, the whole tool is reversed so that the laser light points to the other side of the vehicle.

7. Compare the left and right distance measurements. A properly aligned radar sensor will have the same measurement from side to side. If these two dimensions are within 1/8” (3 mm), no alignment is necessary. If

not, follow the instructions in Section 6.10: Lateral Adjustment Procedure.

6.09 CHECK THE RADAR SENSOR LA TERAL ALIGNMENT

See Section 6.06 for available Bendix® Alignment Tools.

Tools needed: 7 mm box wrench, Bendix® alignment tool and a tape measure.

1. Park the vehicle on a ﬂ at, level surface. The vertical

alignment must be checked and adjusted, if needed, before the lateral adjustment can be made.

2. Remove the cover as shown previously in Section 6.05:

Cover Removal.

3. Position the alignment tool over the radar sensor so that it straddles the radar sensor. Attach the alignment tool to the bracket / radar sensor assembly with its magnet

attachments. See Figures 33 and 34.

4. Activate the lateral alignment laser light “on” switch.

For kits K041451 or K041227, position and place it in

its cradle, making sure it is sitting level, and align the laser beam between the reference lines on the Bendix

alignment tool left or right. See Figure 32.

For kit K065284, place the tool into postion for the ﬁ rst

measurement. (The tool will be reversed when the second measurement is made.)

FIGURE 35 - LATERAL ALIGNMENT VERIFICA TION

NOTE: The lateral alignment also can be checked with

Bendix ACom® Diagnostics (version 6.3 or higher). A value between -0.8° and 0.8 ° is acceptable and the system should operate normally. A value between

-0.8° to -1.3° OR 0.8° to 1.3° means the radar sensor is misaligned and system performance will be degraded. The service technician should align the radar sensor using the procedures noted in this section.

If the value is less than (<) -1.3°, or greater than

(>) 1.3°, the system will typically issue a Diagnostic Trouble Code. The service technician should align the radar sensor laterally. A positive value means the radar sensor should be aligned toward the driver side. A negative value means the radar sensor should be aligned towards the passenger side. The vehicle must

be driven at least 20 miles between adjustments. See

“Alignment Value” in Figure 17.

6.10 LATERAL ADJUSTMENT PROCEDURE

NOTE: Complete these steps only if a vertical adjustment is necessary.

1. Loosen the four lateral position screws. DO NOT fully

remove them. See Figure 36.

B1 Operator Interface

The Bendix Bendix

Wingman® Advanced

Driver Interface Unit (DIU) to communicate with the driver. (For integrated systems, see the vehicle

operator’s manual for more information.)

This Section describes the functions of the DIU. The DIU mounts in, or on, the vehicle dash and provides the interface between the driver and the Advanced system. The DIU provides visual and audio warnings to the driver and accepts input from the driver through the “Up”, “Down” and “OK” buttons.

The DIU contains an internal speaker to provide audible warnings, 2 LED arrays (one each in yellow and red), a single orange and blue LED and an LCD screen for visual warnings, and a light radar sensor to distinguish between day and night conditions.

™

system is either integrated into the vehicle's dash or console, or uses the

B1.1 Start-Up Mode

At initialization, the DIU executes self-test routines during which the following screens are displayed and all

LEDs are activated (power-on bulb check) for approximately 3 seconds. If conﬁ gured, a power-up tone is

also sounded.

Page 38

Appendix B

Driver Interface Unit: Displays & Alerts

B1.3 Volume

Selecting “Volume” from the main menu displays the following screen:

(No LEDs Illuminated)

Volume

The driver uses the up ( )/down ( ) arrow buttons to change the volume. Pressing the “OK” button exits this menu item.

The modiﬁ ed volume setting will be retained through ignition cycles unless conﬁ gured not to do so. If not conﬁ gured, the volume setting will default to 100% on each new ignition cycle.

NOTE: The DIU can be conﬁ gured to limit the minimum volume setting that the driver can select. The bar shown above always represents the adjustable range based on minimum and maximum values. For example, if the minimum value is set to 50% (midpoint between lowest (70 +/- 3dB) and highest (89 +/- 3dB) audio levels, the bar represents an adjustable range from 50% (approx. 80dB) to 100% (approx. 89dB). Once the minimum (or maximum) has been reached, a message will be shown indicating that further adjustment is not allowed (e.g. “Minimum volume reached”). The step change per button press is approximately 2dB.

B1.4 Distance Setting (Dist. Setting)

On systems where changes are permitted, the “Distance Setting” option from the main menu will adjust the following distance that the Bendix

distance mode. Distance Settings 1, 2, 3, and 4 will have different meanings based on the conﬁ guration chosen by

the user in Bendix® ACom® Diagnostics (version 6.3 or higher). Generally, 4 relates to the farthest distance setting

available and 1 relates to the closest distance setting available. In many of the Advanced conﬁ gurations available

in ACom®, two or more distance settings may be made equivalent to one another.

For more information on user conﬁ gurations available through the Bendix ACom Diagnostics software, see Section 5.4: Conﬁ guring Bendix Wingman Advanced Following Distance Alerts in this Service Data sheet for further information.

system will attempt to maintain while in the following

Selecting “Dist. Setting” from the main menu displays the following screen:

(No LEDs Illuminated)

B1.5 Distance Units (Dist. Units)

From the “Dist. Units” menu item, the user may choose to have the following distance from the forward vehicle displayed in either seconds or feet. By default, this item is set to seconds. If the user selects feet, the DIU will display the approximate distance from the bumper to the selected forward vehicle in feet. If the user selects seconds, the DIU will display the approximate distance from the bumper to the selected forward vehicle in seconds.

NOTE: Following distance in seconds is calculated based on the current speed of the Wingman Advanced-equipped truck, and the distance, in feet, away from the selected forward vehicle. For instance, if the selected forward vehicle is 88 feet from the bumper of the Wingman Advanced-equipped truck, and the Wingman Advanced-equipped truck is traveling 60 mph, then the following distance in seconds would be 1.0 seconds because a truck traveling 60 mph can travel 88 feet in one (1) second.

B1.6 US/Metric

From this menu item, the user may select whether English or Metric units are displayed. For instance in “metric” mode, the following distance is shown in meters. In “US” mode, the following distance is shown in feet.

B1.7 Brightness

Selecting Brightness from the main menu displays the following screen:

(No LEDs Illuminated)

Brightness

The driver uses the up ( )/down ( ) arrow buttons to change the LCD backlighting, LED brightness and button backlighting. Pressing the OK button exits this menu item.

The light radar sensor reading determines whether the current cab lighting mode is bright (day) or dark (night). When the light mode is bright, any brightness adjustment made by the driver is applied to only the bright mode setting. Likewise, when the light radar sensor sets the light mode to dark, any brightness adjustment made by the driver is applied to only the dark mode setting. This functionality allows the driver to adjust the brightness setting for the two cab lighting conditions after which the DIU will automatically toggle between the two settings based on the light radar sensor’s input. Both the bright mode setting and the dark mode setting are stored across power cycles.

NOTE: The DIU does not allow the brightness control to completely shut off the LEDs.

B1.8 System Status

This screen shows the conﬁ gured features of the system and their current operational status (i.e., “Failed”

or “OK”). The failed status means that some system malfunction is preventing the feature from properly operating and that the feature is not available for use by the driver at this time. Pressing “OK” exits this menu item.

will not be shown in the demonstration mode.

The screens presented to the driver in the demonstration mode are shown with the following text: “Error! Reference source not found.”

B3.0 Following Distance Alerts (FDAs)

One of the features of the Bendix

Wingman® Advanced

proprietary system combining vehicle speed, forward vehicle speed, distance, and driving scenario, FDAs are used to provide the driver with distance alerts which are intelligent, in that they will give appropriate distance alerts for the given situation. They alert the driver to objects far ahead in highway and country road driving

situations while not over-alerting in dense city trafﬁ c. The radar sensor uses the DIU to communicate the FDA alerts to the driver. This system can be conﬁ gured

through Bendix® ACom

Diagnostics software (version 6.3 or higher), for use by a ﬂ eet as a driver training tool

with or without coordinating the data made available by Wingman Advanced. In addition to being a reminder of when a driver may be dangerously close to the vehicle ahead, the following distance alerts may also be

conﬁ gured to reinforce safe following distance habits taught by the ﬂ eet.

The FDA is based on the following interval between the host vehicle and the object ahead. In other words, this is the time required by the host vehicle to travel forward and reach the object’s current location. With the

exception of the volume, the FDA may not be adjusted by the driver through the DIU. A qualiﬁ ed technician

must connect to the vehicle through the diagnostic port and run ACom® Diagnostics (version 6.3 or higher),

in order to change the conﬁ guration. The volume can not be turned all the way down, but other adjustments may be made by the ﬂ eet. See Section B1.3 for more details on volume adjustment.

The FDA system is intended only to alert the driver about following distance. For more information on alerts

for forward objects with high relative velocities and sudden decelerations, see Section B4.0: Impact Alert.

Only objects detected in the vehicle's lane, traveling in the same direction, are considered valid objects for the

FDA. For more information on stationary objects, see Section B5.0: Stationary Object Alert.

See Section 5.4: Conﬁ guring Bendix Wingman Advanced Following Distance Alerts.

B3.1 Object Detected

When there is no valid object detected and no other high priority alert is displayed, the DIU will stand by with the following screen:

(No LEDs Illuminated)

When a valid object is detected, and is outside the range of the ﬁ rst level of alert, and no other higher priority

alert is displayed, the DIU will display the following and no audio tones will be issued. The distance to the object will be displayed in large characters in the white space at the center of the screen (not shown) in seconds, feet, or meters, depending on the menu-selected preferences. By default, seconds will be displayed.

Object Detected

(No LEDs Illuminated)

B3.2 Following Distance Alert (FDA) Level 1 (Slow audible two-tone alert/single LED illuminated)

When FDA Level 1 is issued, the following distance to the object/vehicle ahead has been reduced to the

distance determined in the current conﬁ guration for FDA Level 1. The DIU will begin to give the driver audio

and visual alerts for as long as the forward vehicle is in this zone and traveling at the same speed or slower.

The DIU will not display following distance units while in an FDA Level. For FDA Level 1, the audible alert will be a single repeating tone, and the visual alert is a single yellow LED and a screen with the vehicles slightly closer as shown below.

Object Detected

Single Yellow LEDs Illuminated

B3.3 Following Distance Alert (FDA) Level 2 (Medium audible two-tone alert/two LED’ s illuminated)

The DIU will give the driver audio and visual alerts for as long as the object/vehicle ahead is in this zone and traveling at the same speed or slower. The DIU will not display following distance while in an FDA Level. For FDA Level 2, the audible alert will be a repeating double tone, and the visual alert is two yellow LEDs and a screen with the vehicles closer as shown below.

B4.0 Impact Alert (IA)

The “Impact Alert”, uses a combination of distance to the vehicle ahead, plus high relative velocity, to decide when to issue a loud solid tone, as well as a visual indicator to the driver. The red LED bar across the top of the DIU will

illuminate and “Wingman Adv. Requires DRIVER INTERVENTION” will ﬂ ash using the two screens below:

When the Impact Alert activates, the driver must immediately act to potentially avoid, or lessen the severity of, a collision.

The impact alert can not be conﬁ gured or turned off.

NOTE: At most, the adaptive cruise control with braking feature of Bendix® Wingman® Advanced™ will apply up to one-third of the vehicle’s braking capacity. The driver must apply additional braking, when necessary, in order to maintain a safe distance from the vehicle ahead.

B4.1 Collision Mitigation

If a collision is likely to occur, and the collision mitigation feature activates the foundation brakes, the tone of the alert will typically change and the display will be as shown below. The driver must immediately act to potentially avoid, or lessen the severity of, a collision.

B5.0 Stationary Object Alert (SOA)

Stationary Object Alert (SOA) is an alert given to the driver when the radar detects a sizeable, nonmoving metallic object in the vehicle's path of travel. To reduce the number of false detections, such as bridges and

overhead signs, an advanced set of ﬁ lters are put in place so the SOA will not warn on every stationary object. The SOA can be conﬁ gured to be on or off through the display. If a SOA is issued, the DIU will very brieﬂ y send out an alert identical to a very brief FDA Level 2: continuous

tone and two yellow LEDs, with the display image switching between the two shown below.

B7.0 Brake Overuse Alert

Using cruise control on downhill runs is the primary cause for this alert to be activated. Cruise control should

NOT be used on downhill grades. Approach grades as you would normally , with the appropriate gear selected and at a safe speed.

To guard against foundation brake overuse by the adaptive cruise control with braking feature of the Bendix

Advanced

™

system, the frequency of foundation brake interventions is monitored. If the system detects a situation where the brakes are being applied too frequently by the system in a given time period, the brake overuse alert will activate. This is designed to help prevent overheating of the brakes, which may lead to brake fade and reduced vehicle

braking capability. In this situation, the Brake Overuse Alert will ﬂ ash a message requesting driver intervention. Also, an

audible alert will sound and a blue LED will blink on the Bendix Driver Interface Unit (DIU), as illustrated below:

This alert will continue for 15 seconds, during which time the driver should step on the brake or turn off cruise control using the cruise control on/off switch.

• The intervention cancels cruise control.

• After a Brake Overuse Alert, for a period of time (typically 20 minutes), the Wingman

Advanced system will not use the foundation brakes when intervening. The system

will be limited to de-throttling the engine and applying the engine retarder during this time.
