10-Way Cluster Harness Connector Pin Call-Out:

Test speedometer, tachometer and other gauges for malfunction using the following:
1. First perform Cluster Self-Diagnostics (Refer to ELECTRICAL/INSTRUMENT CLUSTER - STANDARD PROCEDURE). If there is a response, watch for the effected gauge(s) for operation. Replace cluster as necessary If there is no response to the cluster self-diagnostics, go to Step 2.
2. Remove the cluster (Refer to ELECTRICAL/INSTRUMENT CLUSTER - REMOVAL).
3. Check for ignition voltage at Pin 14 of the 26-way cluster wire harness connector. Refer to Wiring Diagrams for connector views. Check for battery voltage at Pin 4 of the 26-way connector. If no voltage, repair as necessary.
4. Check Pin 1 of the 26-way connector for continuity to ground. If no ground, repair as necessary.
5. If the voltage and ground are OK, and the pins or the connectors are not distorted, replace the instrument cluster (Refer to ELECTRICAL/INSTRUMENT CLUSTER - REMOVAL).
