Trunk/Liftgate Sensor/Switch (For Alarm): Description and Operation
Luggage Compartment Switch, Lighting
Luggage Compartment Switch, Lighting
The tailgate sensor is a contact integrated into the lock mechanism on the tailgate which is also used to control the luggage compartment lighting. The
contact is connected to pin 35 of the control module.
Function
A pulse width-modulated (approx. 3.5%) voltage is supplied continuously from the control module via a 1 kohm pull-up in TWICE to the switch. From
this voltage, the control module can detect whether the tailgate is opened when the alarm is armed by testing the voltage at the input concerned.
