Instrument Cluster Circuit
Disconnect instrument cluster harness connectors "B" and "C". See Figure. Using DVOM, check circuit values at appropriate instrument cluster harness connectors and ensure values are as specified. See INSTRUMENT CLUSTER CIRCUIT VALUES table. If circuit values are not as specified, repair appropriate circuit as necessary. See WIRING DIAGRAMS .
