Ignition Lock Cylinder Control Actuator

WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

The vehicle it is equipped with a floor mounted console gear shifter, and has a ignition lock cylinder control actuator system in the steering column as an added safety feature. The ignition lock cylinder control actuator 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 ignition lock cylinder control actuator system consists of the BCM, the lock cylinder relay, and the ignition lock cylinder control actuator. The ignition lock cylinder control actuator contains a pin that is spring loaded out 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. First, remove the black plug covering the hole.
