Test 7A - Loss Of Ignition Run Only
- Remove and inspect fuse No. 16. If fuse is not good, go to step 3). If fuse is good, use a voltmeter to measure ignition switch output circuit at Fuse #16. If voltage is below 10.0 volts, repair open ignition switch output circuit. If voltage is above 10.0 volts, go to next step.
- Reinstall fuse No. 16. Disconnect battery and wait 2 minutes before proceeding. Disconnect air bag control module 13-way connector. Turn ignition on, then reconnect battery. Use a voltmeter to measure fused ignition switch output run (CAV 2) at ACM. If voltage is above 10.0 volts, perform TEST 15A - ACM REPLACEMENT PROCEDURE . If below 10.0 volts, repair open fused ignition switch output run only circuit.
- Turn ignition off. Use ohmmeter to measure fused ignition switch output run circuit at fuse No. 16. If resistance is below 5.0 ohms, replace fuse. If above 5.0 ohms, disconnect battery and wait 2 minutes before proceeding.
- Disconnect air bag control module 13-way connector. Turn ignition on, then reconnect battery. Use ohmmeter to measure fused ignition output run circuit (CAV 2) at ACM 13-way connector. If resistance is below 5.0 ohms, repair fused ignition switch output circuit for a short to ground. If resistance is below 5.0 ohms, replace fuse. Under both conditions, perform TEST 15A - ACM REPLACEMENT PROCEDURE .
