Inspection and Verification
- Verify the customer concern.
- Visually inspect for obvious signs of electrical damage. VISUAL INSPECTION CHART Electrical Wiring, terminals or connectors
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- NOTE: Make sure to use the latest scan tool software release If 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»(ref-382388) , 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 in the ON state. 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-382407) to diagnose no power in RUN. Verify the scan tool operation with a known good vehicle. Refer to «MODULE COMMUNICATIONS NETWORK»(ref-382388) 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»(ref-382388) . 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 Body Control Module (BCM).
- If the DTCs retrieved are related to the concern, go to the «BODY CONTROL MODULE (BCM) DTC CHART»(ref-382389-S12049203892011012300000) .
- If no DTCs related to the concern are retrieved, go to «SYMPTOM CHART»(ref-382389-S21234129092011012300000) .
