- 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), power lumbar or power recliner seat(s) and the cause is not visually evident, verify the symptom and GO to SYMPTOM CHART .
- If the concern is with the memory seat or climate controlled seat and the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).
-
NOTE: The Vehicle Communication Module (VCM) LED prove out confirms power and ground from the DLC are provided to the VCM.
If the scan tool does not communicate with the VCM:
- check the VCM connection to the vehicle.
- check the scan tool connection to the VCM.
- refer to MODULE COMMUNICATIONS NETWORK , No Power To The Scan Tool, to diagnose no power to the scan tool.
- If the scan tool does not communicate with the vehicle:
- verify the ignition is ON.
- verify the scan tool operation with a known good vehicle.
- refer to MODULE COMMUNICATIONS NETWORK to diagnose no response from the PCM.
- Carry out the network test.
- If the scan tool responds with no communication for one or more modules, refer to MODULE COMMUNICATIONS NETWORK .
- If the network test passes, retrieve and record on-demand and Continuous Memory Diagnostic Trouble Codes (CMDTCs).
- Clear the CMDTCs and carry out the self-test diagnostics for the DSM or DCSM.
- If the DTCs retrieved are related to the concern, go to Driver Seat Module (DSM) DTC Chart or Dual Climate Controlled Seat Module (DCSM) DTC Chart .
- If no DTCs related to the concern are retrieved, GO to SYMPTOM CHART .
