WARNING
Improper use of the Bendix® 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 Bendix® Wingman® Advanced™ system is an integrated
combination of three features:
• Adaptive cruise control with braking;
• Alerts (several different types); 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 sensor mounted to the front of the vehicle
— with a range of approximately 500 feet — 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
FOR THE BENDIX® WINGMAN®

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

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

The GRAY area approximates the zone where the
Wingman Advanced system – when cruise control
is set – is ready to intervene with up to one-third
of the vehicle’s braking capacity, if needed.
Detected Forward Vehicle
BEAM
NOT TO SCALE
1
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
(c) apply the foundation brakes,
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
imposed by factory-set road speed governors, etc. are fully
supported by the Wingman Advanced system.
PART 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 2. The Wingman Advanced
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.
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 guidelines should be observed AT ALL TIMES:
▲ Park the vehicle on a level surface, apply the

WHEN NOT TO USE BENDIX WINGMAN
ADVANCED ADAPTIVE CRUISE
CONTROL WITH BRAKING
The adaptive cruise control with braking feature in
Wingman Advanced is automatically ready when
normal cruise control is set.
WARNING: 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/Low Visibility
Situations – Do not use cruise control
in inclement weather or low visibility
conditions such as rain, snow, smoke, fog,
ice or other severe weather conditions
that may affect the performance of the
Wingman Advanced system.
• Dense Trafc – Do not use cruise control
in heavy trafc.
• 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.
1.1 IMPORTANT SAFETY INFORMATION
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.
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.
• 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
difcult 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 along with any updates
to these limitations and restrictions.

AUTOMATIC FOUNDATION
BRAKE APPLICATIONS
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.
®
1.2 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 Alerts and Warnings section of this manual
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.
1.3 ACTIVATING THE BENDIX®
WINGMAN® ADVANCED™ 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 F.
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.

1.5 HOW A DRIVER INTERACTS WITH THE BENDIX® WINGMAN® ADVANCED™ SYSTEM
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.
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.
How a Driver Interacts with Bendix® Wingman® Advanced™ (1.5)
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

Covers or blocks the radar.
Uses normal cruise control
“+/-” switch.
TABLE 2 - HOW A DRIVER INTERACTS WITH BENDIX® WINGMAN® ADVANCED™
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.
7
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 Bendix® 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.
1.7 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 APPLICATIONS
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).
1.8 ALERTS AND WARNINGS
The Bendix Wingman Advanced system operates 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.
1.6 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.
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 F, 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.
8
IMPACT ALERT (IA)
FOLLOWING DISTANCE ALERT (FDA)
The Impact Alert is the most severe warning issued
by the Bendix® 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 one and a half (1.5) 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
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.
* 1.5 seconds is the system
default and may vary by
eet/OEM.

FIGURE 10 - FOLLOWING DISTANCE ALERT
STATIONARY OBJECT ALERT (SOA)
Stationary Object Alert (SOA) – The Bendix
Wingman® Advanced™ system will give up to a three (3)
second alert to the driver when approaching a detected,
sizable, metallic (radar-reective), 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.
®
9
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 F7.0).
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
1.9 WINGMAN ADVANCED SYSTEM
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 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® Driver Interface Unit (DIU) is used,
volume adjustment is permitted.
1.12 POTENTIAL FALSE ALERTS
In certain unusual trafc or roadway conditions, Wingman
Advanced may issue a false alert.
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
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 guidelines should be observed AT ALL TIMES:
▲ Park the vehicle on a level surface, apply the
parking brakes and always block the wheels.
Always wear personal protection equipment.
▲ Stop the engine and remove the 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.
▲ 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.
▲ 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® AD-IS® air dryer system, a Bendix® DRM™
dryer reservoir module, or a Bendix® AD-9si™ air
dryer, be sure to drain the purge reservoir.
▲ Following the vehicle manufacturer’s
recommended procedures, deactivate the
electrical system in a manner that safely removes
all electrical power from the vehicle.
▲ Never exceed manufacturer’s recommended
pressures.
▲ 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.
▲ Use only genuine Bendix® brand replacement
parts, components and kits. Replacement
hardware, tubing, hose, ttings, etc. must be of
equivalent size, type and strength as original
equipment and be designed speci cally for such
applications and systems.
▲ Components with stripped threads or damaged
parts should be replaced rather than repaired.
Do not attempt repairs requiring machining or
welding unless speci cally stated and approved
by the vehicle and component manufacturer.
▲ Prior to returning the vehicle to service, make
certain all components and systems are restored
to their proper operating condition.
▲ 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.
▲ The power MUST be temporarily disconnected
from the radar sensor whenever any tests USING
A DYNAMOMETER are conducted on a Bendix
Wingman® Advanced™-equipped vehicle.
®
▲ You should consult the vehicle manufacturer's operating and service manuals, and any related literature,
in conjunction with the Guidelines above.
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.

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 qualied 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 inated 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
benets 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 bracket or radar. Never use the radar unit
as a step. NOTE: If the radar sensor was originally
installed behind a panel, check the panel for damage,
etc. that may impact the radar’s performance before
reinstalling. Replace the panel, if necessary, with an
original OEM supplied panel. Do not paint over the
panel.
3. Perform appropriate inspections of the braking system
as required by the manufacturer to ensure brakes are
in proper working order.
4. Ensure that the tires are properly inated 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, bumper guards, snow plows
or similar potential obstructions is not recommended, and
could impair the operation of the radar. See Appendix A3.
Radar Damage/Tampering - In cases where the
bumper and/or radar have sustained any damage, or if you
suspect that the radar has been tampered with, do not use
the cruise control until the vehicle has been repaired. 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.
12
NOTE: Any vehicle trouble code that disables vehicle
cruise control will also cause a diagnostic trouble code in
Wingman Advanced.

3.1 TROUBLESHOOTING BASICS
This section introduces three initial steps to accurately
troubleshoot the Bendix® Wingman® Advanced™ system.
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, a
current version of Bendix® ACom® Diagnostics software will
be required. This software is available as a free download
from www.bendix.com.
Which
radar
sensor is
installed?
The Wingman Advanced
(FLR20) system covered
in this SD sheet has a
at rectangular radar
sensor.
If your Wingman Advanced
system has a black “eyeball”
(FLR10) radar sensor, use
SD sheet SD-61-4962 instead
(formerly SD-13-4962.)
Troubleshooting Basics (3.1)
Questions Next Steps
Have the driver run the
Power-Up Self-Test.
Power-Up Self-Test
This is a self diagnostic check, to determine if the system operation is normal.
1.
Park the vehicle. Power off.
2.
Put the key into the ignition, and turn to the “ignition power” position.
3.
Toggle the cruise control switch at least once, and leave it in the “on” position.
4.
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.
5.
The self-test will start after 15 seconds, and takes approximately 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 briey display a distance alert message and/or cause the Forward Vehicle
Detected icon in the instrument cluster to illuminate; this is normal.
Does the driver hear a
long warning beep?
Have the driver describe the
system behavior that they
believe shows it is not working
properly.
TABLE 3 - TROUBLESHOOTING BASICS
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 system (typically with a status indicator/dash icon illuminated).
For descriptions of all DTCs, see Section 4.3: Diagnostic Trouble Codes.
When diagnosing the system, especially in cases where there are no diagnostic
trouble codes logged, nd out which part of the system behavior appears to be
operating improperly. See Section 3.2: Narrowing Down the Problem.
13
3.2 NARROWING DOWN THE PROBLEM
Use the questions found in Table 3.2 below to help assess if the Bendix® Wingman® Advanced™ system is not performing
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 (1-800-247-2725, option 2), complete the
Troubleshooting Checklist (See Appendix E), to help reduce the time needed to troubleshoot the system.
Narrowing Down the Problem (3.2)
Questions Next Steps
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?
Mounting Problems
Is the radar sensor mounting location
(bumper or cross-member) damaged?
• 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 mounting bracket look damaged or
tampered with?
Other Questions
Has the system worked properly in the past
and is not working correctly now?
Clean the radar sensor front surface immediately. Remove anything blocking the
radar sensor then power cycle and read any remaining trouble codes.
Read Section 4.3: Diagnostic Trouble Codes.
Read Appendix A3: FLR20 Radar Sensor Mounting Clearance.
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 may log a diagnostic trouble code (DTC).
After the blockage is removed, the DTC will clear automatically when the vehicle’s
ignition is cycled.
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 dene the driving condition presenting the problems. Review proper
operating conditions in the operator's manual.
Re-align the radar sensor vertically and laterally. Use the following procedures:
• Inspect the radar mounting. A solid mounting surface is necessary in order
to hold the alignment. If the bumper or mounting cross-member is damaged,
replace it rst, then align the radar sensor.
• Appendix B1 - Go to Appendix B1 and use the owchart to nd out the
procedure needed. Follow the actions directed in the procedure and align
the radar.
• Appendix B4 - Check the vertical alignment and adjust if needed.
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 (6.6) and adjust if needed.
• Check the Lateral Alignment (6.8) 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 rst, then align the radar sensor.
This is a good indication that something has changed; review the questions listed
above with the driver to further diagnose the problem.
Has the radar sensor been changed
recently?
TABLE 4 - NARROWING DOWN THE PROBLEM (PAGES 14-15)
14
If so, the new radar sensor may be incompatible with the vehicle. In addition,
check any system trouble codes with Bendix® ACom® Diagnostics software.
Read Section 4.3: Diagnostic Trouble Codes.
Narrowing Down the Problem (3.2)
Questions Next Steps
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 when
using ACB to slow the vehicle, but the code
goes away later?
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 determine if
the radar system interventions are not the expected Bendix Wingman Advanced
behavior. If the radar system interventions are not typical, the radar sensor may
be misaligned.
• Inspect the radar mounting. A solid mounting surface is necessary in order
to hold the alignment. If the bumper or mounting cross-member is damaged,
replace it rst, then align the radar sensor.
• Appendix B1 - Go to Appendix B1 and use the owchart to nd out the
procedure needed. Follow the actions directed in the procedure and align
the radar.
• Appendix B4 - Check the vertical alignment and adjust if needed.
The service technician will need to check trouble codes as well. Read Section
4.3: Diagnostic Trouble Codes.
In normal operation, the adaptive cruise control with braking feature of Bendix®
Wingman® Advanced™ system may indicate a DTC 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 set a DTC, 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 pull off the road, and cycle the ignition to before the
vehicle’s cruise control can be used.
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 chafed, 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. Verify there are no
diagnostic trouble codes. Proper downgrade driving techniques should be used.
Read Section 4.3: Diagnostic Trouble Codes.
Does the radar sensor have noticeable
damage beyond normal discoloration or
surface scratches?
TABLE 4 - NARROWING DOWN THE PROBLEM (PAGES 14-15)
The radar sensor and bracket are very durable. However, if the radar sensor
housing or cover is cracked or broken, immediately look for trouble codes via a
current version of Bendix® ACom® Diagnostics and replace the damaged radar
sensor. Read Section 4.3: Diagnostic Trouble Codes, and Appendix A.02: Radar
Sensor Mounting.

3.3 OVERVIEW OF POSSIBLE ISSUES
Some customer issues are actually misunderstandings of how the Bendix® Wingman® Advanced™ system performs
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.

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® ABS,
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)
with the system may report dissatisfaction over 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: Troubleshooting Basics to verify if the system is functioning normally;
then continue.
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 system doesn’t seem to work at all, the radar sensor may possibly be blocked. A DTC
will also be set. Visually inspect it, clear the blockage, turn the ignition on and run through a
power cycle. See Appendix A3 for more information about radar mounting clearance.
If the vehicle has been in an accident, it is likely the radar sensor will need to be re-aligned
or replaced. Inspect the radar sensor and housing for damage. Radar sensor discoloration
or small scratches may be acceptable. Signicant damage (such as cracks, or broken
pieces) 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 chang. Refer to Sections
4.5: Troubleshooting Diagnostic Trouble Codes: Power Supply and 4.6 Serial Data (J1939)
Communications Link of this document for additional troubleshooting.
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 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 Appendix B -
Bendix Wingman Advanced Radar Alignment.

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 Trouble Codes: Power
