Diagnostic Procedure
- Turn ignition off. Disconnect ECM harness connector. See Figure
. Remove instrument cluster. Check continuity of Pink/Blue wire between instrument cluster harness connector M32 terminal No. 32 and ECM harness connector terminal No. 68. See Figure
and Fig 1
. Also, check circuit for short to ground and short to voltage. If problem is found, go to next step. If problem is not found, go to step 3
.
- Check the following:
- Check for poor connection at White, 18-pin harness connector F66 terminal No. 2 (Pink/Blue wire). See Figure
. Connector is located under instrument panel. See Figure
.
- Check for open or short between instrument cluster and ECM.
Repair as necessary.
- Reconnect all harness connectors. Check speedometer operation. If speedometer operates properly, go to step 5
. If speedometer does not operate properly, go to next step.
- Check the following:
- Check for poor connection at Super Multiple Junction (SMJ) connector M15 terminal 13D (Red wire). See Fig 2
. SMJ connector M15 is located under left side of instrument panel. See Figure
.
- Check for poor connection at White, 20-pin connector M230 terminal No. 2 (Red wire). See Figure
. Connector M230 is located under center of instrument panel. See Figure
.
- Check for poor connection at Gray, 8-pin connector F65 terminal No. 3 (Red wire). See Figure
. Connector F65 is located on left side of engine compartment. See Figure
.
- Check for open or short between instrument cluster and Vehicle Speed Sensor (VSS).
- Check for open or short between instrument cluster and ABS/TCS control unit.
- Check for open or short between VSS, transmission control module and ECM.
Repair as necessary.
- No problem is indicated at this time. Problem may be intermittent. See INTERMITTENTS
