B1A43-SECURITY TRANSMITTER SENSOR RETURN CIRCUIT LOW





For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
During the Vehicle Theft and Security System (VTSS) pre-arm process.

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





1. DETERMINING IF DIAGNOSTIC TROUBLE CODE (DTC) IS CURRENT

NOTE: Diagnose any related Communication DTCs before continuing.

1. With a scan tool, read and record DTCs.
2. With the scan tool, clear DTCs.
3. Turn the ignition off and remove the key from the ignition.
4. Lock and close all doors to allow the VTSS to go from pre-arm to armed status and wait one minute.
5. Disarm the VTSS.
6. Using the scan tool, read DTCs.

Does the DTC reset?

Yes

- Go To 2

No

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

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




1. Turn the ignition off.
2. Disconnect the Intrusion Sensor Transmitter connector.
3. Disconnect the Intrusion Transceiver Module connector.
4. Measure the resistance between ground and the (G945) Sensor Ground circuit at the Intrusion Sensor Transmitter connector.

Is the resistance below 5.0 ohms?

Yes

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

No

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