Pinpoint Test F: The Ignition Key Can Be Removed from the Ignition Lock Cylinder Regardless of Transmission Selector Lever Position

Refer to Wiring Diagram Set 13, Power Distribution/SJB for schematic and connector information. Diagrams By Number

Normal Operation

When the transmission selector lever is placed in a position other than PARK, the key release interlock actuator (part of the ignition switch assembly) prevents the key from being removed from the ignition lock cylinder. The key release interlock actuator receives fused battery voltage from Smart Junction Box (SJB) fuse 8 (15A) along circuit SBP08 (VT/RD). Ground for the solenoid is provided along circuit CDC41 (WH/BN), through the park detection switch (internal to the transmission selector lever) and then along circuit GD138 (BK/WH). When the transmission selector lever is placed in a position other than PARK the park detection switch applies ground to circuit CDC41 (WH/BN). This prevents the key from being removed from the ignition lock cylinder.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Ignition switch
- Transmission selector lever



PINPOINT TEST F: THE IGNITION KEY CAN BE REMOVED FROM THE IGNITION LOCK CYLINDER REGARDLESS OF TRANSMISSION SELECTOR LEVER POSITION

NOTICE: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multi-meter probes.

-------------------------------------------------
F1 CHECK CIRCUIT CDC41 (WH/BN) FOR AN OPEN


- Ignition OFF.
- Disconnect: Transmission Selector Lever C2008.
- Disconnect: Ignition Switch C250.
- Measure the resistance between ignition switch C250-3 circuit CDC41 (WH/BN), harness side and transmission selector lever C2008-3, circuit CDC41 (WH/BN), harness side.




- Is the resistance less than 5 ohms?

Yes
GO to F2.

No
REPAIR circuit CDC41 (WH/BN). TEST the system for normal operation.

-------------------------------------------------
F2 CHECK CIRCUIT 1205 (BK) FOR AN OPEN


- Measure the resistance between transmission selector lever C2008-6, circuit GD138 (BK/WH), harness side and ground.




- Is the resistance less than 5 ohms?

Yes
GO to F3.

No
REPAIR circuit CDC138 (BK/WH). TEST the system for normal operation.

-------------------------------------------------
F3 CHECK THE PARK DETECTION SWITCH


- Connect: Ignition Switch C250.
- Ignition ON.
- Apply the parking brake and place the transmission selector lever in the NEUTRAL position.
- Connect a fused jumper wire between transmission selector lever C2008-3, circuit CDC41 (WH/BN), harness side and transmission selector lever C2008-6, circuit GD138 (BK/WH) harness side.
- Can the ignition key be removed from the lock cylinder?

Yes
INSTALL a new ignition switch. REFER to Ignition Switch Ignition Switch. TEST the system for normal operation.

No
INSTALL a new transmission selector lever. TEST the system for normal operation.
