Column Ignition Lock

The DeVille Touring Sedan (DTS) is equipped with a floor mounted console gear shifter, and has a column ignition lock system in the steering column as an added safety feature. The column ignition lock systems purpose is to prevent the steering wheel from being locked when the transmission is in gear and the vehicle may still be moving. The column ignition lock system consists of the rear integration module (RIM), the lock cylinder relay, and the park key lock actuator. The park key lock actuator contains a pin that is spring loaded outward to mechanically prevent the ignition key cylinder from being turned to the LOCK position when vehicle speed is above 5 MPH for 15 seconds and the transmission is not in the Park position. If vehicle power is lost, and/or the transmission is not in the Park position, the operator will not be able to turn the ignition key to the LOCK position and will not be able to remove the ignition key from the column. For situations where the vehicle must be towed, the system can be overridden by pressing a release button that is reached through an access hole located on the under side of the steering column. A black plug covering the hole must first be removed.
