Inspection and Verification
- Verify the customer concern.
- Visually inspect for obvious signs of electrical damage. VISUAL INSPECTION CHART Electrical Body Control Module (BCM)
- 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 cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).
- 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»(ref-494551) , 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. The air bag warning indicator prove-out confirms ignition ON (other indicators may not prove ignition ON). If the ignition does not turn on, refer to «STEERING COLUMN SWITCHES»(ref-494582) to diagnose no power in RUN. verify the scan tool operation with a known good vehicle. refer to «MODULE COMMUNICATIONS NETWORK»(ref-494551) to diagnose no response from the PCM.
- Carry out the network test. If the scan tool responds with no communication with one or more modules, refer to «MODULE COMMUNICATIONS NETWORK»(ref-494551) . If the network test passes, retrieve and record the continuous memory DTCs.
- Clear the continuous DTCs and carry out the self-test diagnostics for the BCM.
- If the DTCs retrieved are related to the concern, go to the «Body Control Module (BCM) DTC Chart»(ref-494579-S31932197492012081400000) .
- If no DTCs related to the concern are retrieved, GO to «SYMPTOM CHART»(ref-494579-S41153835392012081400000) .
