Hi,
In case of system malfunction, the shift lever can be released by pushing a key into the release slot near the shift lever.
Here is information on exactly how the system works it will help you in diagnosing the problem:
Shift Lock System
Voltage is provided at all times through fuse 25 to the key interlock switch. When you push the key in, voltage is provided to the key interlock solenoid, and the interlock control unit. You can then turn the key "off", and remove it. However, if the automatic transmission gear position switch is not in park, the interlock control unit will provide ground to the key interlock solenoid, energizing it so the key cannot be removed.
Key Interlock System
With the ignition switch in "run" or "start", voltage is provided to the shift lock solenoid through fuse 1. When the automatic transmission gear position switch is in park, the transmission control module (TCM) provides voltage to the shift lock circuit, provided the brake pedal is pushed and the throttle is not. Ground is provided to the shift lock solenoid through the automatic transmission gear position switch. The solenoid then energizes, releasing the automatic transmission gear lever.
Thank you
Joe T.
