Normal Operations and Fault Conditions

The ignition switch contains a key removal inhibit solenoid. The key removal inhibit solenoid prevents the ignition lock cylinder from being turned to lock and the key removed any time the transmission selector lever is in any position except park. The key removal inhibit solenoid receives voltage at all times from the BCM (Body Control Module) fuse 28 (15A). When the transmission selector lever is in any gear except park, the selector switch closes, which supplies ground to the solenoid.

Pinpoint Test

1. CHECK FOR AN ENERGIZED KEY REMOVAL INHIBIT SOLENOID

1. Remove the BCM (Body Control Module) fuse 28 (15A).

2. Attempt to turn the ignition key to the ON position and then back to the lock position and remove the key.

Does the ignition lock cylinder turn to the lock position and can the key be removed?








2. CHECK THE IGNITION LOCK CYLINDER FOR BINDING

1. Remove the ignition lock cylinder. REFER to Ignition Lock Cylinder .

2. Rotate the ignition lock cylinder through all positions using the key.

Does the ignition lock cylinder freely rotate through all positions and can the key be removed from the lock cylinder?
