Liftgate Key Cylinder Unlock Switch
WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.
If equipped, the liftgate key cylinder unlock switch uses a discrete input to the BCM. The BCM utilizes this input to enable access into the rear compartment area without causing the alarm to sound. The CTD system remains armed until one of the disarm procedures are performed.
