B1A3B-SECURITY RECEIVER SENSOR CIRCUIT HIGH





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

- When Monitored:
When the VTSS is armed.

- Set Condition:
If the current flow on the sensor signal circuit is above a specified range this DTC will set.





1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, record and erase DTCs.
3. Turn the ignition off and remove the key from the ignition.

6. Turn the ignition on and with the scan tool, read DTCs.

Does the scan tool display B1A3B-SECURITY RECEIVER SENSOR CIRCUIT HIGH ?

Yes

- Go To 2

No

- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform the BODY VERIFICATION TEST. Body Verification Test

2. CHECK THE (G460) INTRUSION RECEIVER SENSOR SIGNAL CIRCUIT SHORT TO VOLTAGE




1. Turn the ignition off.
2. Disconnect the Intrusion Sensor Receiver connector.
3. Disconnect the Intrusion Transceiver Module connector.
4. Measure for voltage between chassis ground and the (G460) Intrusion Receiver Sensor Signal circuit at the Intrusion Transceiver Module connector.

Is there any voltage present?

Yes

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

No

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