B1A43-SECURITY TRANSMITTER SENSOR RETURN CIRCUIT LOW
For a complete wiring diagram Refer to Section 8W.
- 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.
| Possible Causes |
| INTRUSION SENSOR TRANSMITTER (G945) SENSOR GROUND CIRCUIT SHORTED TO GROUND |
| INTRUSION TRANSCEIVER MODULE |
Diagnostic Test
1. DETERMINING IF DTC IS CURRENTNOTE: 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
- Perform BODY VERIFICATION TEST – VER 1 (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
No
- DTC is not active at this time. Test complete.
- Perform BODY VERIFICATION TEST – VER 1 (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
2. CHECK THE (G945) SENSOR GROUND CIRCUIT SHORTED TO GROUND
Turn the ignition off.
Disconnect the Intrusion Sensor Transmitter connector.
Disconnect the Intrusion Transceiver Module connector.
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 BODY VERIFICATION TEST – VER 1 (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
No
- Replace the Intrusion Transceiver Module in accordance with the Service Information.
- Perform BODY VERIFICATION TEST – VER 1 (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
