The Ignition Key Cannot Be Returned to the OFF Position 

Refer to Shift Interlock for schematic and connector information.

Normal Operation and Fault Conditions 

The key removal inhibit solenoid (part of the ignition switch) receives battery voltage from BCM fuse 28 (15A). When the selector lever is moved into the PARK position, the park range switch (part of the selector lever) opens, interrupting a ground circuit to the key removal inhibit solenoid. The key removal inhibit solenoid deactivates and allows the ignition lock cylinder to be turned to the OFF position and the key to be removed.
