1 - Checking the tilt sensor
2 - Checking the movement sensor
-------------------------------------------------
Checking the tilt sensor
Check the rear electronic module connector and the tilt sensor connector for defects and an open-circuit.
Check the ground connection between tilt sensor connector terminal #5 and ground terminal 31/72. Check the cable and connector in the cable harness between these two points. See Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault and Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.

2. Verifying the movement sensor.
1 - Verifying the tilt sensor
2 - Verifying the movement sensor
-------------------------------------------------
Verifying the movement sensor
- Open the window. Lock the car with the remote control.
- Wait 25 seconds until the alarm is active. Then trigger the alarm by reaching into the car.
Does the alarm go off?
Yes - Procedure complete
No - Information
-------------------------------------------------
Verifying the tilt sensor
- Open the tailgate and press in the striker plate so that it cannot be closed.
- Lock the car with the remote control.
- Wait 25 seconds until the alarm is active. Trigger the alarm by detaching the tilt sensor and twisting it.
Does the alarm go off?
Yes - Procedure complete
No - Information

Information
Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
Yes - Exit Fault-Tracing
No - Attempt New Test
