Diagnostic Test

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 step 2
  No
  - DTC is not active at this time. Test complete.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure
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 step 3
  No

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. Refer to DTC-Based Diagnostics/MODULE, Front Control (FCM) - Standard Procedure
  No
  - Replace the Intrusion Transceiver Module in accordance with the Service Information.
