For a complete wiring diagram consult Diagrams/Electrical.


- When Monitored:
During the VTSS pre-arm process.

- Set Condition:
The Intrusion Transceiver Module detects a short to ground condition on the sensor ground circuit.








Diagnostic Test


1. DETERMINING IF DTC IS CURRENT
NOTE: Diagnose any related Communication DTC(s) before continuing.

With a scan tool, read and record DTC(s).
With the scan tool, clear DTC(s).
Turn the ignition off and remove the key from the ignition.
Lock and close all doors to allow the VTSS to go from pre-arm to armed status and wait one minute.
Disarm the VTSS.
Using the scan tool, read DTC(s).
Does the DTC reset?

Yes


- Go to 2
- Perform BODY VERIFICATION TEST - VER 1Body Verification Test


No


- DTC is not active at this time. Test complete.
- Perform BODY VERIFICATION TEST - VER 1Body Verification Test




2. CHECK THE (G945) SENSOR GROUND CIRCUIT SHORTED TO GROUND




Turn the ignition is off.
Disconnect the Intrusion Sensor Transmitter connector.
Disconnect the Intrusion Transceiver Module connector.
Measure the resistance between ground and the (G945) Intrusion Transmitter Sensor Ground circuit at the Intrusion Sensor Transmitter connector.
Is the resistance below 5.0 ohms?

Yes


- Repair the (G945) Intrusion Transmitter Sensor Ground circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1Body Verification Test


No


- Replace the Intrusion Transceiver Module.
- Perform BODY VERIFICATION TEST - VER 1Body Verification Test
