Diagnostic Test
- TEST FOR INTERMITTENT CONDITION
- Turn the ignition on.
- With the scan tool, record and erase DTCs.
- Turn the ignition off and remove the key from the ignition.
- Close all doors and arm the VTSS and wait two minutes.
- Disarm the VTSS turn the ignition on.
- Turn the ignition on and with the scan tool, read DTCs.
Does the scan tool display B1A3A-SECURITY RECEIVER SENSOR CIRCUIT LOW ?
Yes
- Go to step 2
No
- The conditions that caused this code to set are not present at this time. Using the SYSTEM WIRING DIAGRAMS as a guide, inspect the wiring and connectors.
- Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure
- INTRUSION SENSOR RECEIVER
- Turn the ignition off.
- Disconnect the Intrusion Sensor Receiver connector.
- Turn the ignition on and with the scan tool, erase DTCs.
- Turn the ignition off and remove the key from the ignition.
- Close all doors and arm the VTSS and wait two minutes.
- Disarm the VTSS turn the ignition on.
- With the scan tool, read DTCs.
Does the scan tool display B1A44-SECURITY RECEIVER SENSOR CIRCUIT OPEN?
Yes
- Replace the Intrusion Sensor Receiver.
- Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure
No
- Go to step 3
- CHECK THE (G460) INTRUSION RECEIVER SENSOR SIGNAL CIRCUIT SHORT TO GROUND
- Turn the ignition off.
- Disconnect the Intrusion Transceiver Module connector.
- Measure the resistance between ground and the (G460) Intrusion Receiver Sensor Signal circuit at the Intrusion Transceiver Module connector.
Is the resistance below 5.0 ohms?
Yes
- Repair the (G460) Intrusion Receiver Sensor Signal circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure
No
- Replace the Intrusion Transceiver Module in accordance with the Service Information.
