The intrusion sensor detects movement within the vehicle while parked. B+ is supplied to the intrusion sensor at all times and the rear integration module (RIM) arms the sensor using the intrusion sensor armed signal circuit. If movement is detected while armed, RIM is informed via the intrusion sensor alarm on signal circuit. The RIM will then sound the content theft alarm.

1. Ignition OFF, disconnect the harness connector at the intrusion sensor.
2. Ignition ON, verify a test lamp illuminates between the B+ circuit terminal A and ground.

⇒	If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

3. Ignition OFF, disconnect the X2 harness connector at the RIM.
4. Ignition ON, test for less than 1 volt between the following signal circuit terminals and ground:

•	Signal circuit terminal 11

•	Signal circuit terminal 20

⇒	If greater than the specified range, test the signal circuit for a short to ground.

5. Test for infinite resistance between the following signal circuit terminals and ground:

•	Signal circuit terminal 11

•	Signal circuit terminal 20

⇒	If less than the specified value, test the signal circuit for a short to ground.

6. Test for less than 2 ohms between the signal circuit terminal 11 at the RIM and the signal circuit terminal C at the inclination sensor.

⇒	If greater than the specified range, test the signal circuit for an open/high resistance.

7. Test for less than 2 ohms between the signal circuit terminal 20 at the RIM and the signal circuit terminal B at the inclination sensor.

⇒	If greater than the specified range, test the signal circuit for an open/high resistance.

8. If all circuits test normal, test or replace the intrusion sensor.
