Tilt Sensor

The tilt sensor is situated on the left side of the luggage compartment. Its purpose is to measure the vehicle parked angle when the DWA is armed.

The tilt sensor wire uses three wires:

DWA 12v - supply voltage from the BC1 to the tilt sensor.
NG - switched ground output to the BC1
KL 31 - ground
