Shift Interlock: Description and Operation

Circuit Description
The transaxle interlock system performs two functions; it allows the ignition key to be removed only with the transaxle in PARK, and allows the transaxle to be released from PARK with only the brake pedal depressed The transaxle and key lock control module receives voltage from audio fuse with the ignition switch in ACC or ON, and from fuse 1 in ON or START. With the ignition switch in ON, the park position switch closed and the brake pedal switch depressed, the transaxle and key lock control module grounds the shift lock solenoid. The solenoid is energized, allowing the gear selector to be moved out of the PARK position.

When the ignition switch is in ON or ACC and the gear selector is moved to PARK , the key lock switch is closed and the transaxle and key lock control module de-energizes the key lock solenoid. This allows the ignition key to be removed. In case the shift lock solenoid does not energize and release the gear selector when the brake pedal is depressed, a button beneath the console can be accessed by removing the plug at the top of the console and inserting a thin instrument to manually release the gear selector from PARK.
