- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the concern is with the power seat (non-memory seat) or climate controlled seat and the cause is not visually evident, verify the symptom and GO to SYMPTOM CHART .
- If the concern is with the memory seat and the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
- Check that the program card is correctly installed.
- Check the connections to the vehicle.
- Check the ignition switch position.
- If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool manual.
- Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
- CAN circuit fault; all electronic control units no response/not equipped, refer to MODULE COMMUNICATIONS NETWORK .
- No response/not equipped for driver seat module (DSM), refer to MULTIFUNCTION ELECTRONIC CONTROL MODULES .
- No response/not equipped for dual climate controlled seat module (DCSM), refer to MODULE COMMUNICATIONS NETWORK .
- No response/not equipped for driver door module (DDM), refer to MULTIFUNCTION ELECTRONIC CONTROL MODULES .
- System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), clear the continuous DTCs and carry out self-test diagnostics for the DSM.
- System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), clear the continuous DTCs and carry out self-test diagnostics for the DCSM.
- System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), clear the continuous DTCs and carry out self-test diagnostics for the DDM.
- If the DTCs retrieved are related to the concern, go to DRIVER SEAT MODULE (DSM) DIAGNOSTIC TROUBLE CODE (DTC) INDEX , DUAL CLIMATE CONTROLLED SEAT MODULE (DCSM) DIAGNOSTIC TROUBLE CODE (DTC) INDEX and DRIVER DOOR MODULE (DDM) DIAGNOSTIC TROUBLE CODE (DTC) INDEX .
- If no DTCs related to the concern are retrieved, GO to SYMPTOM CHART .
