Attention.
- Improper handling of the SAS control unit can cause the airbag modules and pretensioners to inadvertently deploy, resulting in serious injury. Service warnings must be read before starting work on the SAS control unit.
- If the connector is connected and the ignition is turned on without properly securing the SAS control unit with the mounting nuts, the SAS control unit may register an impact even with an accidental light touch, which will cause the airbag modules and seat belt pretensioners to deploy.
- If the DSC sensors initialization procedure is not completed, the stability control system will not function properly, which may result in an accident.
- Therefore, if the SAS control unit is replaced, the DSC sensors must be initialized to ensure proper system operation.
- If the SAS control unit is not configured after replacement, specific information will not be stored in the SAS control unit and the system will not operate normally.
- If the SAS control unit is replaced, it is imperative to complete the configuration procedure before removing the SAS control unit. If the configuration fails or the SAS control unit is removed, fault code 80003:53 is displayed.
- To perform the configuration, it is necessary to read the vehicle-specific information from the old SAS control unit before replacing it. To do this, connect the M-MDS to the diagnostic socket and carry out vehicle identification before removing the SAS control unit. Vehicle-specific information is temporarily stored in the M-MDS.
Note:
- The SAS control unit stores vehicle-specific information before replacement. The new SAS control unit does not have any vehicle-specific information.
- If the specific information from the old SAS control unit was not read before it was replaced, the unit must be configured using the built-in data.
1. If the SAS control unit is to be replaced, configure it.
2. Turn off the ignition.
3. Disconnect the negative battery terminal and wait at least one minute.
4. Remove the following parts:
- Front console box.
- Versions with manual gearbox: gear lever knob.
- Shift lever panel.
- Top panel.
- Rear console.
5. Remove the parking brake lever to the side so that it does not interfere with work.
6. Disconnect connectors.
7. To turn away bolts.
8. Remove the SAS control unit.
9. Installation is made in an order, the return to removal.
10. Turn on the ignition (engine off or on).
11. Verify that the airbag system indicator flashes for 6 seconds and goes out. If the airbag system indicator does not illuminate, perform a system check using the on-board self-diagnosis using the M-MDS.
12. Perform the procedure for initializing the sensors of the dynamic stabilization system.
Note: If the configuration cannot be done by writing the pre-read vehicle-specific information, perform the configuration using the built-in information after replacing the SAS control unit.
SAS control unit configuration
With read/save function
Note: When configuring, it is necessary to read specific information from the SAS control unit before replacing it. Connect the M-MDS to the vehicle connector and perform vehicle identification before removing the SAS control unit from the vehicle. Vehicle-specific information is temporarily stored in the M-MDS.
1. Connect the M-MDS device to the DLC-2 connector.
2. After identifying the vehicle, select the parameter "Module Programming" (module programming) from the home screen of the M-MDS instrument.
3. Then select options from the OSD menu in the following order:
- Choose "Programmable Module Installation" (installation of a programmable module).
- Choose "RCM".
4. Complete the configuration according to the prompts on the screen.
Attention. When performing a configuration, the CAN connection between the four-wheel drive control unit and other control units connected by the CAN bus may be temporarily interrupted with the appearance of the corresponding fault code. After completing the configuration, it is necessary to check for fault codes in the control units connected to the CAN bus, and, if found, delete these codes.
5. Check for fault codes in control units connected to the CAN bus. If fault codes are found, delete them. After deleting the codes, complete the procedure, since the configuration is over. If trouble codes do not clear, troubleshoot for the problem that is found.
Using Embedded Data
Note: If the configuration is performed using embedded data, the personalization setting is reset to the original (state of delivery from the factory). After completing the configuration using the built-in data, you need to configure the personalization settings.
1. Connect the M-MDS device to the DLC-2 connector.
2. After identifying the vehicle, select the parameter "Module Programming" (module programming) from the home screen of the M-MDS instrument.
3. Then select options from the OSD menu in the following order:
- Choose "As-Built" (embedded data).
- Choose "RCM".
4. Complete the configuration according to the prompts on the screen.
