Rear Compartment Lid Ajar Switch

The CTD system uses the rear compartment lid ajar switch in the rear compartment lid latch assembly as one method to activate the alarm. The RIM monitors the rear compartment lid ajar switch via a discrete input. When the rear compartment lid is opened the ajar switch grounds the input to the RIM. When the CTD system is in the armed mode, the RIM activates the alarm.

IMPORTANT: The CTD system can be armed with the windows or sunroof open.
