Inspection and Verification
- Verify the customer concern.
- Visually inspect the following for obvious signs of mechanical or electrical damage.VISUAL INSPECTION CHART
Mechanical Electrical - Engine coolant level
- Accessory drive belt
- Engine oil level
- Brake fluid level
- Circuitry
- Smart junction box (SJB) fuse 28 (10A)
- Instrument cluster
- Message center switches
- 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 , No Power To The Scan Tool, to diagnose no communication with the scan tool.
- 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 MODULE COMMUNICATIONS NETWORK to diagnose no response from the powertrain control module (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 the continuous memory DTCs.
- Clear the continuous DTCs and carry out the self-test diagnostics for the instrument cluster.
- If the DTCs retrieved are related to the concern, refer to the Instrument Cluster Diagnostic Trouble Code (DTC) Index.
- If no DTCs related to the concern are retrieved, go to Symptom Chart .
NOTE:
Make sure to use the latest scan tool software release.
NOTE:
The vehicle communication module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM.
