Inspection and Verification
INSPECTION AND VERIFICATION1. Verify the customer concern by operating the system.
Visual Inspection Chart:
2. Visually inspect for obvious signs of mechanical or electrical damage.
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the concern is with the power seat (non-memory seat) or heated seats and the cause is not visually evident, verify the symptom and GO to Symptom Chart. Symptom Related Diagnostic Procedures
5. NOTE: Before carrying out diagnostic testing for the driver seat module (DSM) wake the module by activating the power seat using the seat control switch, otherwise module communication failure will occur.
If the concern is with the memory seat or climate controlled 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.
6. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
7. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
- SCP+, SCP- or UBP circuit fault; all electronic control units no response/not equipped, refer to Information Bus (Module Communications Network).
- No response not equipped for DSM, GO to Symptom Chart. Symptom Related Diagnostic Procedures
- No response not equipped for CCSM, GO to Pinpoint Test M. Test M: A Single Climate Controlled Seat Does Not Operate/Does Not Operate Correctly
- System passed for the DSM, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the DSM.
- System passed for the CCSM, retrieve and record the continuous DTCs, erase the continuous DTCs and carry out self-test diagnostics for the CCSM.
8. If the DTCs retrieved are related to the concern, go to Driver Seat Module (DSM) Diagnostic Trouble Code (DTC) Index or the Climate Controlled Seat Module (CCSM) Diagnostic Trouble Code (DTC) Index.
