B1A45

B1A45-SECURITY RECEIVER SENSOR CIRCUIT SHORTED TOGETHER





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

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

- Set Condition:
If the voltage current is below a specified range this DTC will set.





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. INTRUSION SENSOR RECEIVER
1. Disconnect the Intrusion Sensor Receiver connector.

NOTE: Check connectors - Clean/repair as necessary.

2. Connect a known good Intrusion Sensor Receiver.
3. Turn the ignition on.
4. With the scan tool, clear DTCs.
5. Turn the ignition off and remove the key from the ignition.
6. Lock and close all doors to allow the VTSS to go from pre-arm to armed status and wait one minute.
7. Disarm the VTSS.
8. Using the scan tool, read DTCs.

Does the DTC reset?

Yes

- Go To 3

No

- Replace the original Intrusion Sensor Receiver.
- Perform the BODY VERIFICATION TEST. Body Verification Test

3. CHECK THE (G460) INTRUSION RECEIVER SENSOR SIGNAL WIRE FOR A SHORT TO (G946) SENSOR GROUND




1. Turn the ignition off.
2. Disconnect the Intrusion Sensor Transceiver connector.
3. Disconnect the Intrusion Transceiver Module connector.
4. Measure the resistance between the (G460) Intrusion Receiver Sensor Signal circuit to the (G946) Sensor Ground circuit in the Intrusion Sensor Receiver connector.

Is the resistance below 5.0 ohms?

Yes

- Repair the (G460) Intrusion Receiver Sensor Signal circuit for a short to the (G946) Sensor Ground circuit.
- Perform the BODY VERIFICATION TEST. Body Verification Test

No

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