Test 146C - Repairing Key In Ignition Circuit
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
NOTE:
Perform TEST 146A before proceeding with this test.
- Disconnect ignition switch connector. See Fig 1. Ensure connector is clean and undamaged. Using scan tool in ohmmeter mode, check resistance of ignition switch connector terminal No. 4 (Black wire). If resistance is more than 5 ohms, repair open Black wire. If resistance is less than 5 ohms, go to next step.
- Connect jumper wire between ignition switch connector terminals No. 4 (Black wire) and No. 6 (Light Blue wire). Using scan tool, read key in ignition switch status. If scan tool displays KEY IN IGN CLOSED, replace ignition switch. If scan tool does not display KEY IN IGN CLOSED, go to next step.
- With connectors connected, connect jumper wire between Body Control Module (BCM) connector terminal No. 20 (Light Blue wire) and ground. Using scan tool, read key in ignition switch status. If scan tool displays KEY IN IGN CLOSED, repair open Light Blue wire. If scan tool does not display KEY IN IGN CLOSED, go to next step.
- Turn ignition switch to OFF position. Disconnect BCM Bone connector. Ensure connector is clean and undamaged. If any terminals are damaged, repair connector as necessary. If terminals are okay, replace BCM.
