Pinpoint Test Z: Unable To Remove The Key From The Ignition Lock Cylinder

Refer to Wiring Diagram Set 37, Shift Interlock for schematic and connector information. Diagrams By Number

Normal Operation

The ignition switch contains a key removal inhibit solenoid. The solenoid prevents the ignition lock cylinder to be turned to lock and the key removed any time the transmission selector lever is in any position except park (automatic transaxle only). The inhibit solenoid receives voltage at all times from the Battery Junction Box (BJB) fuse 14 (15A) on circuit SBB14 (BN/RD). When the transmission selector lever is in any gear except park, the selector switch closes and connects circuit GD116 (BK/VT) to circuit CET22 (GY/BN), which supplies ground to the solenoid.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors
- Transmission selector lever
- Binding steering column components
- Ignition lock cylinder
- Ignition switch



PINPOINT TEST Z: UNABLE TO REMOVE THE KEY FROM THE IGNITION LOCK CYLINDER

-------------------------------------------------
Z1 CHECK FOR AN ENERGIZED KEY REMOVAL INHIBIT SOLENOID


- Remove the BJB fuse 14 (15A).
- Attempt to turn the ignition key to the run 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?

Yes
REFER to Steering Column to continue diagnosis of the key removal inhibit solenoid system. Testing and Inspection

No
GO to Z2.

-------------------------------------------------
Z2 CHECK THE IGNITION LOCK CYLINDER FOR BINDING


- Remove the ignition lock cylinder. REFER to Ignition Lock Cylinder Service and Repair.
- 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?

Yes
REFER to Steering Column to continue diagnosis of the steering column for any binding steering column components or ignition switch. Testing and Inspection

No
INSTALL a new ignition lock cylinder. REFER to Ignition Lock Cylinder Service and Repair. TEST the system for normal operation.
