A: Connector C1 Pin-Out Test
^ Measure all voltages to ground with the Ignition Switch in RUN.
^ Measure all resistances to ground with the Ignition Switch in OFF and negative Battery Cable disconnected.
^ Check all ground terminals with a self-powered test lamp before making voltage or resistance measurements.
^ If the correct voltage or resistance is not found at the terminal, do the test given.
^ If the correct voltage or resistance is found at the 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).
