B1A45-SECURITY RECEIVER SENSOR CIRCUIT SHORTED TOGETHER
For a complete wiring diagram Refer to Section 8W.
- When Monitored:
During the VTSS pre-arm process.
- Set Condition:
If the voltage current is below a specified range this DTC will set.
| Possible Causes |
| INTRUSION SENSOR RECEIVER |
| (G460) INTRUSION RECEIVER SENSOR SIGNAL SHORTED TO (G946) SENSOR 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
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. INTRUSION SENSOR RECEIVER
Disconnect the Intrusion Sensor Receiver connector.
NOTE: Check connectors - Clean/repair as necessary.
Connect a known good Intrusion Sensor Receiver.
Turn the ignition on.
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 To3
No
- Replace the original Intrusion Sensor Receiver.
- Perform BODY VERIFICATION TEST – VER 1 (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
3. CHECK THE (G460) INTRUSION RECEIVER SENSOR SIGNAL WIRE FOR A SHORT TO (G946) SENSOR GROUND
Turn the ignition off.
Disconnect the Intrusion Sensor Transceiver connector.
Disconnect the Intrusion Transceiver Module connector.
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 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)
