Pinpoint Test K: The Ignition Key Can Be Turned to the OFF Position When the Selector Lever is Not In PARK

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

Normal Operation

The key removal inhibit solenoid (part of the ignition switch) receives battery voltage from Central Junction Box (CJB) fuse 1 (15A). Moving the selector lever out of the PARK position closes the park detect switch (part of the selector lever) and provides a ground path for the key removal inhibit solenoid. The ground path activates the solenoid and prevents the ignition lock cylinder from being turned to the OFF position, which prevents the ignition key from being removed. The Instrument Panel Cluster (IPC) also receives input from the park detect switch along the same circuit as the key removal inhibit solenoid.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- Key removal inhibit solenoid (part of the ignition switch)

- Park detect switch (part of the selector lever)

PINPOINT TEST K : THE IGNITION KEY CAN BE TURNED TO THE OFF POSITION WHEN THE SELECTOR LEVER IS NOT IN PARK

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

K1 CHECK THE KEY INHIBIT SOLENOID CIRCUIT FOR GROUND

- Select NEUTRAL.

- Disconnect: Ignition Switch C250.

- Measure the resistance between ignition switch C250-3, circuit CDC41 (WH/BN), harness side and ground.





Is the resistance less than 5 ohms?

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

No
GO to K2.

K2 CHECK THE KEY INHIBIT SOLENOID CIRCUIT FOR AN OPEN

- Disconnect: Floor Shifter C3245.

- Measure the resistance between ignition switch C250-3, circuit CDC41 (WH/BN), harness side and floor shifter C3245-2, circuit CDC41 (WH/BN), harness side.





Is the resistance less than 5 ohms?

Yes
GO to K3.

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

K3 CHECK THE FLOOR SHIFTER GROUND CIRCUIT FOR AN OPEN

- Measure the resistance between floor shifter C3245-5, circuit GD115 (BK/GY), harness side and ground.





Is the resistance less than 5 ohms?

Yes
INSTALL a new selector lever (floor shifter). TEST the system for normal operation.

No
REPAIR circuit GD115 (BK/GY). TEST the system for normal operation.
