Circuit/System Description

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2012 GMC Yukon XL, 2012 GMC Yukon, 2012 Chevrolet Tahoe, 2012 Chevrolet Suburban, and 2012 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The key cylinder unlock feature will unlock the driver door only with a single turn to the unlock position and all of the doors when the driver door switch (DDS) receives two consecutive turns to the unlock position and will send a request to the passenger door switch (PDS) and the BCM to unlock all of the doors.
