A: Connector Pin-Out Test

^ Measure all voltages to ground with the Ignition Switch in RUN.

^ Measure all resistances to ground with the Ignition Switch OFF and negative Battery Cable disconnected.

^ Check all ground terminals with a self-powered test lamp before making voltage and resistance measurements.

^ If the correct voltage or resistance is not found at a terminal, do the test given or go to the test referred.

^ If the correct voltage or resistance is not found at a terminal, and the function that uses that terminal does not operate and all appropriate incandescent bulbs have been checked, replace the Instrument Cluster (see Service and Repair).
