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).
NOTE: Make sure to use the latest scan tool software release.
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 PINPOINT TEST AF: NO POWER TO THE SCAN TOOL to diagnose no power to the scan tool.
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 vehicle:
- Verify the ignition key is in the ON position.
- Verify the scan tool operation with a known good vehicle.
- Refer to PINPOINT TEST A: THE PCM DOES NOT RESPOND TO THE SCAN TOOL 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 INSPECTION AND VERIFICATION .
- 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 SJB , Driver Door Module (DDM) and the Instrument Panel Cluster (IPC).
