Tilt Sensor

TILT SENSOR







Located in the electrical carrier forward of the glove box, the tilt sensor is an electronic sensing device with the sole purpose of monitoring the vehicle's parked angle when DWA is armed.

The sensor requires three signal wires to perform its function:
- KL 30 - Constant battery voltage
- Signal "STDWA"; switched ground input signal provided by the GM indicating DWA armed/disarmed status. The tilt sensor is used as a splice location for the STDWA signal to the Siren and FIS interior protection sensor.
- Signal "NG"; switched ground output signal provided to the GM. The signal is used for two purposes,
1. As a momentary acknowledgment that the tilt sensor received STDWA and is currently monitoring the vehicle angle.
2. If the tilt sensor detects a change in the vehicle's angle when DWA is armed, signal NG is switched to inform the GM to activate the siren.

When the tilt sensor receives the STDWA signal from the GM it memorizes the vehicle's parked angle. The angle of the vehicle is monitored by the solid state electronics. Once armed, if the angle changes, the tilt sensor provides a switched ground signal to the GM to activate DWA.
