For a complete wiring diagram Refer to Diagrams/Electrical.

- When Monitored:

During the VTSS pre-arm process.

- Set Condition:

The Intrusion Transceiver Module detects a short to battery 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 to2

No

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

2.CHECK THE (G946) INTRUSION RECEIVER SENSOR GROUND CIRCUIT SHORT TO BATTERY





Turn the ignition off.

Disconnect the Intrusion Sensor Receiver connector.

Disconnect the Intrusion Transceiver Module connector.

Turn the ignition on.

Measure the voltage of the (G946) Intrusion Receiver Sensor Ground circuit in the Intrusion Sensor Receiver connector.

Is there any voltage present?

Yes

- Repair the (G946) Intrusion Receiver Sensor Ground circuit for a short to voltage.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Go To3
