Inspection and Verification
1. Verify the customer concern.
2. Visually inspect the following for obvious signs of mechanical or electrical damage.

Visual Inspection Chart:

3. If an obvious cause for an observed 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.

4. 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.

5. 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.
- See PINPOINT TEST 7: NO MODULE/NETWORK COMMUNICATION - NO POWER TO THE DIAGNOSTIC TOOL to diagnose no communication with the scan tool. Pinpoint Test 7: No Module/Network Communication - No Power to the Diagnostic Tool

6. 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.
- See COMMUNICATIONS NETWORK. No response from the PCM. Initial Inspection and Diagnostic Overview

7. Carry out the network test
- If the scan tool responds with no communication for one or more modules, see COMMUNICATIONS NETWORK. Initial Inspection and Diagnostic Overview
- If the network test passes, retrieve and record continuous memory diagnostic trouble codes (DTCs).

8. Clear the continuous DTCs and carry out the self-test diagnostics for the instrument cluster.
9. If the DTCs retrieved are related to the concern, see INSTRUMENT CLUSTER DIAGNOSTIC TROUBLE CODE (DTC) INDEX. Instrumentation/Driver Information
10. If no DTCs related to the concern are retrieved, see SYMPTOM TROUBLESHOOTING CHART - INSTRUMENT CLUSTER. Instrument Cluster
