Trunk/Liftgate Sensor/Switch (For Alarm): Description and Operation
Luggage Compartment Switch, Lighting
General
The boot lid/tailgate sensor is a switch that is integrated in the locking mechanism. It is also used to control the luggage compartment lighting. The
switch is connected to pin 35 on the control module.
Function
A continuous pulse width modulated (approx. 3.5%) voltage is supplied from the control module via a 1 kohm pull-up in TWICE to the switch. By
checking this voltage on the control module input, the control module can monitor whether the boot lid/tailgate is opened while the alarm is armed.
