DANGER

When an engine is operating, keep the service area WELL VENTILATED or attach a building exhaust removal system to the engine exhaust system. Engines produce

carbon monoxide, an odorless, poisonous gas that causes slower reaction time and can lead to serious personal injury or loss of life.

It is not advised to use headphones at a high volume

Listening at high volumes for long periods of time may result in loss of hearing.

Safety Warnings

 Always perform automotive testing in a safe environment.

 Wear safety eye protection that meets ANSI standards.

 Keep clothing, hair, hands, tools, test equipment, etc. away from all moving or hot

engine parts.

 Operate the vehicle in a well-ventilated work area, for exhaust gases are

poisonous.

 Put the transmission in PARK (for automatic transmission) or NEUTRAL (for

manual transmission) and make sure the parking brake is engaged.

 Put blocks in front of the drive wheels and never leave the vehicle unattended

while testing.

 Be extra cautious when working around the ignition coil, distributor cap, ignition

wires and spark plugs. These components create hazardous voltages when the engine is running.

 Keep a fire extinguisher suitable for gasoline, chemical, and electrical fires nearby.

 Do not connect or disconnect any test equipment while the ignition is on or the

engine is running.

 Keep the test equipment dry, clean, free from oil, water or grease. Use a mild

detergent on a clean cloth to clean the outside of the equipment as necessary.

 Do not drive the vehicle and operate the test equipment at the same time. Any

distraction may cause an accident.

 Refer to the service manual for the vehicle being serviced and adhere to all

diagnostic procedures and precautions. Failure to do so may result in personal injury or damage to the test equipment.

 To avoid damaging the test equipment or generating false data, make sure the

4.1 Vehicle Communication and Selection

4.1.1 Establish Vehicle Communication

The Diagnostics operations require connecting the MaxiSys MS909 tablet to the test vehicle through the VCI device using the Main Cable and test adapters (for non-OBD II vehicles). To establish proper vehicle communication with the tablet, you need to perform the following steps:

1. Connect the VCI device to the vehicle DLC for both communication and power supply.

2. Connect the VCI device to the tablet via BT pairing, Wi-Fi or USB connection.

3. When the above steps are completed, check the VCI navigation button at the bottom bar on the screen. If a green BT, Wi-Fi or USB icon displays at the lower right corner, the MaxiSys MS909 Diagnostic Platform is ready to start vehicle diagnosis.

4.1.1.1 Vehicle Connection

The method used to connect the VCI device to a vehicle DLC depends on the vehicle configuration as follows:

 A vehicle equipped with an On-board Diagnostics Two (OBD II) management

system supplies both communication and 12-volt power through a standardized J-1962 DLC.

 A vehicle not equipped with an OBD II management system supplies

communication through a DLC connection, and in some cases supplies 12-volt power through the cigarette lighter receptacle or a connection to the vehicle battery.

OBD II Vehicle Connection

This type of connection only requires the main cable without any additional adapter.

 To connect to an OBD II vehicle

1. Connect the main cable’s female adapter to the Vehicle Data Connector on

the VCI device, and tighten the captive screws.

2. Connect the 16-pin male adapter to the vehicle DLC under the vehicle dash.

NOTE

The vehicle DLC is not always located under the dash; refer to the user manual of the test vehicle for additional connection information.

Non-OBD II Vehicle Connection

This type of connection requires both the main cable and a required OBD I adapter for the specific vehicle being serviced.

There are three possible conditions for Non-OBD II vehicle connection:

 DLC connection supplies both communication and power.

 DLC connection supplies communication and power is to be supplied via the

cigarette lighter connection.

 DLC connection supplies communication and power is to be supplied via

4.1.1.2 VCI Connection

After the VCI device is properly connected to the vehicle, the Power LED on the VCI device lights solid green, and is ready to establish communication with the tablet.

Coming with the MaxiSys MS909 tool kit, the VCI device supports three communication methods with the tablet: BT, Wi-Fi and USB.

Pairing Up via BT

The working range for BT communication is about 328 feet (100 m), giving technicians

greater mobility to perform vehicle diagnosis from anywhere in the repair shop.

To expedite multi-vehicle diagnostics, more than one VCI can be used in busy repair shops

enabling technicians to quickly pair via BT their MaxiSys tablet to each VCI separately and

therefore eliminating the need to unplug the VCI from one vehicle and then connect it to

another each time a new vehicle comes in for repairs.

 To pair up the tablet with the VCI device via BT

1. Power up the tablet.

2. Select the VCI Manager application from the MaxiSys Main Screen.

3. The device automatically scans for available VCI devices around for BT

pairing. The found devices are listed in the Setting section on the right side of the screen.

4.9 Programming

Since the introduction of OBD II and leading up to modern Hybrids and EVs, hardware and software technologies in cars have been advancing at an exponential. Upd ating software may be the only way to fix the following issues:

 Drivability

 Fuel Efficiency

 Power Loss

 Fault Codes

 Durability of Mechanical Parts

The Programming and Coding function is used to re-flash the vehicle control modules, which allows you to update the computer software of the vehicle to the latest version, as well as to reprogram adaptive data of certain components after making repairs or replacements.

NOTE

The programming function applies only when the vehicle is connected with a J2534 programming device, which serves as a PassThru interface to establish communication with and transfer data to the vehicle ECU.

Available programming or coding operations vary by test vehicle, and only the available operations display in the menu.

There are two general types of programming operations:

A. Coding – also known as Teach-in Program, or Component Adaptation, is used to

reprogram adaptive data for vehicle control modules after repairs or replacements of vehicle parts.

B. Reprogramming Operations – downloads the latest version of software from the

online server database through Internet access (this procedure is done automatically when the tablet is connected to the Internet, so there is no need to check for software updates yourself), and reprograms the newest version into the vehicle ECU.

NOTE

Ensure that the tablet is connected to the Internet before applying the ECU programming function, so that the tablet can access the manufacturer’s server for update service.

Selecting the Programming or Coding function opens a menu of operation options that varies by make and model. Selecting a menu option either displays a programming interface or opens another menu of additional choices. Follow all screen instructions while performing the programming or coding operations. How and what information is presented on the screen vary by the type of operation being performed.

4.9.1 Coding

The main section of the Coding screen displays a list of vehicle components

or coding options.

Figure 0-32 Sample Coding Screen

The main section of the Coding screen displays a list of vehicle components and the coding information that mainly consists of two parts:

1. All available systems for coding are displayed on the left side, and the coding data or value on the right side.

2. The bottom of the main section displays the functional buttons that enable you to manipulate the operation.

Check the vehicle condition and the coding information carefully. Use the functional button to edit Codes for the corresponding components. Tap Send when you have finished editing all items. When the operation is completed, an execution status message such as Completed, Finished or Successful, may display.

Tap the ESC button to exit the function.

4.9.2 Reprogramming

Before the reprogramming begins:

 Ensure the tablet works in a stable Wi-Fi network.

 Connect the tablet to the VCI by USB.

 Fully charge the tablet battery and connect the tablet to a charger if necessary.

 Attach a battery maintainer to the vehicle battery to maintain a steady voltage

throughout the reprogramming. Voltage requirements differ by vehicle. Consult the

vehicle manufacturer before programming a module.

 Keep the application running during module reprogramming, or the process may

fail and result in permanent damage to the module.

Typical reprogramming operations require you to input and validate VIN number first. Tap the input box and enter the correct number. The programming interface then displays.

Figure 0-33 Sample Reprogramming Operation Screen

The main section of the reprogramming interface offers information of the hardware, the current software version and the newest software versions to be programmed into the control units.

A series of on-screen operational instructions will display to guide you through the programming procedure.

Carefully read the on-screen information and follow the instruction to execute the programming procedure.

4.9.3 Re-flash Errors

IMPORATANT

When reprogramming onboard, always make sure the vehicle battery is fully charged and in good working condition. During reprogramming, the operation may fail if voltage falls below the proper operation voltage. Sometimes a failed operation can be recovered, but the failed reprogramming can also ruin the control module. We recommend connecting an

external battery maintainer to the vehicle to ensure steady voltage throughout the programming. The required voltage differs by vehicle. Consult vehicle manufacturer for correct voltage to be maintained.

Occasionally a flash update procedure may not complete properly. Common causes of flash errors include poor cable connections between the tablet, VCI, and vehicle, the vehicle ignition being switched off before the flash procedure is complete, or low vehicle battery voltage.

If the process quits, recheck all the cable connections to assure good communications and initialize the flash procedure. The programming procedure will automatically repeat if the previous operation fails.

4.10 Generic OBD II Operations

The OBD II/EOBD vehicle diagnosis option offers a quick way to check for DTCs, isolate the cause of a dashboard malfunction indicator lamp (MIL), check monitor status prior to emissions certification testing, verify repairs, and perform other emissions-related services. The OBDII direct access option is also used for testing OBD II/EOBD-compliant vehicles that are not included in the Diagnostics database. Diagnostics toolbar buttons at the top of the screen are available for specific vehicle diagnostics. See Table 4-2 Diagnostics Toolbar Buttons on page 34 for details.

General Procedure

 To access the OBD II/EOBD diagnostics functions

1. Tap the Diagnostics application button in the MaxiSys Main Screen. The

Vehicle Menu displays.

2. Tap the EOBD button. There are two options to establish communication with

the vehicle.

 Auto Scan – select it to establish communication using each protocol in

order to determine which one the vehicle is using.

 Protocol – select it to open a submenu of various protocols. A

communication protocol is a standardized way of data communication between an ECM and a diagnostic tool. Global OBD may use several different communication protocols.

3. Select a specific protocol if the Protocol option is selected. Wait for the OBD

II Diagnostic Menu to appear.

Figure 0-34 Sample OBD II Diagnostic Menu

4. Select a function option to continue.

 DTC & FFD

 I/M Readiness

 Live Data

 O2 Sensor Monitor

 On-Board Monitor

NOTE

Supported functions may vary by vehicle.

Function Descriptions

This section describes the various functions of each diagnostic option:

Trouble Codes

When this function is selected, the screen displays a list of Stored Codes and Pending Codes. When the Freeze Frame data of certain DTCs are available for viewing, a snowflake button will display on the right side of the DTC item. The Erase Codes function can be applied by tapping the functional button at the bottom of the screen.

Figure 0-9 Sample Trouble Codes Screen

 Stored Codes

Stored codes are emission-related DTCs from the ECM of the vehicle. OBD II/EOBD Codes have a priority according to their emission severity, with higher-priority codes overwriting lower-priority ones. The priority of the code determines if a MIL can enact the codes erase procedure. Manufacturers rank codes differently so expect display to vary by vehicle.

 Pending Codes

These are codes whose storing conditions have been met during the last drive cycle, but need to be met on two or more consecutive drive cycles before the DTC stored. The purpose of displaying pending codes is to assist the service technician after a vehicle repair when diagnostic information is cleared, by reporting test results after a single driving cycle.

a) If a test fails during the driving cycle, the DTC associated is reported. If the

pending fault does not occur again within 40 to 80 warm-up cycles, the fault is automatically cleared from memory.

b) Test results reported do not necessarily indicate a faulty component or

system. If test results indicate another failure after additional driving, a DTC is stored to indicate a faulty component or system.

 Freeze Frame

In most cases the stored frame is the last DTC reported. Certain DTCs, those that have a greater impact on vehicle emission, have a higher priority. In these cases, DTC of the highest priority is the one for which the freeze frame records are retained. Freeze frame data includes a “snapshot” of critical parameter values at the time the DTC is stored.

 Erase Codes

This option is used to clear all emission-related diagnostic data including DTCs, freeze frame data and specific manufacturer-enhanced data from the vehicle ECM. This option resets the I/M Readiness Monitor Status for all vehicle monitors to Not Ready or Not Complete status.

A confirmation screen displays when the clear codes option is selected to prevent accidental loss of data. Select Yes on the confirmation screen to continue, or No to exit.

I/M Readiness

This function is used to check the readiness of the monitoring system. It is an excellent function to use prior to having a vehicle inspected for state emissions compliance. Selecting I/M Readiness opens a submenu with two choices:

 Since DTCs Cleared – displays the status of monitors since the last time the DTCs

are erased.

 This Driving Cycle – displays the status of monitors since the beginning of the

current drive cycle.

Live Data

This function enables the display of real-time PID data from the ECU. Displayed data includes analog and digital input and output, and system status information broadcast in the vehicle data stream.

Live data can be displayed in various modes, see 4.5 Live Data on page 45 for detailed information.

O2 Sensor Monitor

This function allows retrieval and review of recent O2 sensor monitor test results stored on the vehicle on-board computer.

The O2 Sensor Monitor test function is not supported by vehicles that communicate using a controller area network (CAN). For O2 Sensor Monitor tests results of CAN-equipped vehicles, refer to On-Board Monitor.

On-Board Monitor

This function allows you to view the results of On-Board Monitor tests. The tests are useful after the service when a vehicle control module memory is already erased.

Component Test

This function enables dual-directional control of the ECM so that the diagnostic tool can transmit control commands to operate the vehicle systems. This function is useful in determining how well the ECM responds to a command.

Vehicle Information

This function enables the display of the vehicle identification number (VIN), calibration identification number, calibration verification number (CVN), and other information of the test vehicle.

Vehicle Status

This function checks the current condition of the vehicle, such as the communication protocols of OBD II modules, number of fault codes, and status of the Malfunction Indicator Light (MIL).

After entering each special function, the screen will display two application choices: Diagnosis and Hot Functions. The Diagnosis enables the reading and clearing of codes which is sometimes necessary after completing certain special functions. Hot Functions consists of sub functions of the selected special function.

Figure 6-1 Sample Service Menu

Several most commonly used services are described in this chapter.

6.1 Oil Reset Service

Perform reset for the Engine Oil Life system, which calculates an optimal oil life change interval depending on the vehicle driving conditions and climate. The Oil Life Reminder must be reset each time the oil is changed, so the system can calculate when the next oil change is required.

NOTE

1. Always reset the engine oil life to 100% after every oil change.

2. All required work must be carried out before the service indicators are reset.

Failure to do so may result in incorrect service values and cause DTCs to be stored by the relevant control module.

3. For some vehicles, the scan tool can reset additional service lights such as

maintenance cycle and service interval. On BMW vehicles for example, service resets include engine oil, spark plugs, front/rear brakes, coolant, particle filter, brake fluid, micro filter, vehicle inspection, exhaust emission inspection and vehicle checks.

6.2 Electric Parking Brake (EPB) Service

This function has a multitude of usages to maintain the electronic braking system safely and effectively. The applications include deactivating and activating the brake control system, assisting with brake fluid control, opening and closing brake pads, and setting brakes after disc or pad replacement.

6.2.1 EPB Safety

It can be dangerous to perform Electric Parking Brake (EPB) system maintenance, so before you begin the service work, please keep these rules in mind.

 Ensure that you are fully familiar with the braking system and its operation before

commencing any work.

 The EPB control system may be required to be deactivated before carrying out

any maintenance/diagnostic work on the brake system. This can be done from the tool menu.

 Only perform maintenance work when the vehicle is stationary and on level

ground.

 Ensure that the EPB control system is reactivated after the maintenance work has

been completed.

NOTE

Autel accepts no responsibility for any accident or injury arising from the maintenance of the Electric Parking Brake system.

6.3 Tire Pressure Monitoring System (TPMS) Service

This function allows you to quickly look up the tire sensor IDs from the vehicle ECU, as well as to perform TPMS replacement and reset procedures after tire sensors are replaced.

6.4 Battery Management System (BMS) Service

BMS allows the tool to evaluate the battery charge state, monitor the close-circuit current, register the battery replacement, activate the rest state of the vehicle, and charge the battery via the diagnostic socket.

NOTE

1. This function is not supported by all vehicles.

2. The sub functions and actual test screens of the BMS may vary by vehicle, please

follow the on-screen instructions to make correct option selection.

The vehicle may use either a sealed lead-acid battery or an Absorbed Glass Mat (AGM) battery. Lead acid battery contains liquid sulphuric acid and can spill when overturned. AGM battery (known as VRLA battery, valve regulated lead acid) also contains sulphuric acid, but the acid is contained in glass mats between terminal plates.

It is recommended that the replacement aftermarket battery has the same specifications, such as capacity and type, as the exiting battery. If the original battery is replaced with a different type of battery (e.g. a lead-acid battery is replaced with an AGM battery) or a battery with a different capacity (mAh), the vehicle may require reprogramming of the new battery type, in addition to, performing the battery reset. Consult the vehicle manual for additional vehicle-specific information.

6.5 Diesel Particle Filter (DPF) Service

The Diesel Particle Filter (DPF) function manages DPF regeneration, DPF component replacement teach-in and DPF teach-in after replacing the engine control unit.

The ECM monitors driving style and selects a suitable time to employ regeneration. Cars driven a lot at idling speed and low load will attempt to regenerate earlier than cars driven more with higher load and speed. For regeneration to take place, a prolonged high exhaust temperature must be obtained.

In the event of the car being driven in such a way that regeneration is not possible, i.e., frequent short journeys, a diagnostic trouble code will eventually be registered in addition to the DPF light and “Check Engine” indicators displaying. A service regeneration can be requested in the workshop using the diagnostic tool.

Before performing a forced DPF regeneration using the tool, check the following items:

 The fuel light is not on.

 No DPF-relevant faults are stored in system.

 The vehicle has the specified engine oil.

 The oil for diesel is not contaminated.

IMPORTANT

Before diagnosing the problem vehicle and attempting to perform an emergency regeneration, it is important to obtain a full diagnostic log and read out relevant measured value blocks.

NOTE

1. The DPF will not regenerate if the engine management light is on, or there is a

faulty EGR valve.

2. The ECU must be re-adapted when replacing the DPF and when topping up the

fuel additive Eolys.

If the vehicle needs to be driven in order to perform a DPF service, a second person is needed for the function. One person should drive the vehicle while the other person observes the screen on the Tool. Do not attempt to drive and observe the scan tool at the same time. This is dangerous and puts your life and the lives of other motors and pedestrians at risk.

6.6 Immobilizer (IMMO) Service

An immobilizer is an anti-theft mechanism that prevents an automobile’s engine from starting unless the correct ignition key or other device is present. This device prevents thieves from starting the car by a method known as hot wiring. Most new vehicles have an immobilizer as standard equipment. An important advantage of this system is that it doesn’t require the car owner to activate it; it operates automatically. An immobilizer is considered as providing much more effective anti-theft protection than an audible alarm alone; many auto insurance companies offer lower rates for vehicles that are equipped with an immobilizer.

As an anti-theft device, an immobilizer disables one of the systems needed to start a car's engine, usually the fuel supply or the ignition. This is accomplished by radio frequency identification between a transponder in the ignition key and a device called a radio frequency reader in the steering column. When the key is placed in the ignition, the transponder sends a signal with a unique identification code to the reader, which relays it to a receiver in the vehicle computer control module. If the code is correct, the computer allows the fuel supply and ignition systems to operate and start the car. If the code is incorrect or absent, the computer disables the system, and the car will be unable to start until the correct key is placed in the ignition.

The IMMO service can disable a lost vehicle key and program the replacement key fob. One or more replacement key fobs can be programmed.

6.7 Steering Angle Sensor (SAS) Service

SAS Calibration permanently stores the current steering wheel position as the straight-ahead position in the SAS EEPROM. Therefore, the front wheels and the steering wheel must be set exactly to the straight-ahead position before calibration. In addition, the VIN is also read from the instrument cluster and stored permanently in the SAS EEPROM. On successful completion of calibration, the SAS fault memory is automatically cleared.

Calibration must always be carried out after the following operations:

 Steering wheel replacement

 SAS replacement

 Any maintenance that involves opening the connector hub from the SAS to the

column

 Any maintenance or repair work on the steering linkage, steering gear or other

related mechanism

 Wheel alignment or wheel track adjustment

 Accident repairs where damage to the SAS or assembly, or any part of the

steering system may have occurred

NOTE

1. Autel accepts no responsibility for any accident or injury arising from servicing the

SAS system. When interpreting DTCs retrieved from the vehicle, always follow the manufacturer’s recommendation for repair.

2. All software screens shown in this manual are examples, and actual test screens

may vary by test vehicle. Pay attention to the menu titles and onscreen instructions to make correct option selections.

3. Before starting procedure, make sure the vehicle has an ESC button. Look for

button on dash.
