Instrument Cluster Test 3

Before performing this test, complete the testing of the hard-wired chime warning system switches as described.

WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIRBAGS AND SEAT BELTS/AIRBAGS BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.

1. Disconnect and isolate the battery negative cable. Remove the instrument cluster from the instrument panel. Refer to Instrument Panel Systems for the procedures.
2. Unplug the headlamp switch and the key in ignition switch wire harness connectors. Check for continuity between the key in switch sense circuit cavity of the right instrument cluster wire harness connector (connector B) and a good ground. There should be no continuity. If OK, go to Step 8. If not OK, repair the short circuit as required.
3. Check for continuity between the key in switch sense circuit cavities of the right instrument cluster wire harness connector (connector B) and the head- Tamp switch wire harness connector. There should be continuity. If OK, go to Step 4. If not OK, repair the open circuit as required.
4. Unplug the driver seat belt switch wire harness connector. Check for continuity between the seat belt switch sense circuit cavity of the right instrument cluster wire harness connector (connector B) and a good ground. There should be no continuity. If OK, go to Step 5. If not OK, repair the short circuit as required.
5. Check for continuity between the seat belt switch sense circuit cavities of the right instrument cluster wire harness connector (connector B) and the driver seat belt switch wire harness connector, There should be continuity. If OK, test the instrument cluster as described in Instrument Panel Systems. If not OK, repair the open circuit as required.
