Test 8A - Loss Of Ignition Run/Start
- Remove and inspect fuse No. 17. If fuse is not good, go to step 4). If fuse is good, go to next step.
- Use voltmeter to measure the ignition switch output circuit at fuse No. 17. If voltage is below 10.0 volts, repair open ignition switch output circuit. If voltage is above 10.0 volts, reinstall fuse No. 17. Disconnect battery and wait 2 minutes before proceeding.
- Disconnect air bag control module 13 ways connector. Turn ignition on, then reconnect battery. Use voltmeter to measure fused ignition switch output run/start circuit (CAV 1) at air bag control module connector. If voltage is below 10.0 volts, repair open fused ignition switch output run/start circuit. If above 10.0 volts, perform TEST 15A - ACM REPLACEMENT PROCEDURE .
- Turn ignition off. Disconnect battery and wait 2 minutes before proceeding. Disconnect air bag control module 13-way connector. Use an ohmmeter to measure the fused ignition switch output circuit (CAV 1) at ACM 13-way connector. If resistance is above 5.0 ohms, replace fuse and perform TEST 15A - ACM REPLACEMENT PROCEDURE . If resistance is below 5.0 ohms, repair fused ignition switch output run/start circuit for a short to ground, replace fuse and perform TEST 15A - ACM REPLACEMENT PROCEDURE .
