Inspection and Verification
- Verify the customer concern.
- Visually inspect the following for obvious signs of electrical damage. VISUAL INSPECTION CHART Electrical Circuitry Key-in-ignition warning switch (part of the ignition switch) Instrument cluster
- 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 connection to the vehicle. Refer to «MODULE COMMUNICATIONS NETWORK»(ref-270934) 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»(ref-270934) to diagnose no response from the powertrain control module (PCM).
- Carry out the network test: If the scan tool responds with no communication for multiple modules, refer to «MODULE COMMUNICATIONS NETWORK»(ref-270934) . If the scan tool responds with no communication with the instrument cluster, refer to «INSTRUMENT CLUSTER»(ref-270940) . 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, go to the Instrument Cluster Diagnostic Trouble Code (DTC) Chart. For all other DTCs, refer to «MULTIFUNCTION ELECTRONIC MODULES»(ref-270935) .
- If no DTCs related to the concern are retrieved, go to «Symptom Chart»(ref-270941-S13602602862007111500000) .
