Rear Compartment Lid Ajar Switch

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2007 GMC Yukon XL, 2007 GMC Yukon, 2007 Chevrolet Tahoe, 2007 Chevrolet Suburban, and 2007 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The CTD system uses the rear compartment lid ajar switch as a status indicator to activate the alarm. The rear compartment lid ajar switch is monitored via a discrete input from the switch. If the BCM receives a ground signal from the lid ajar switch when the CTD system is armed, the BCM activates the alarm.
