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 to2
No
- DTC is not active at this time. Test complete.
- Perform the BODY VERIFICATION TEST. See: Verification Tests/Body Verification Test
2. CHECK THE (G946) SENSOR GROUND CIRCUIT SHORT TO BATTERY
1. Turn the ignition off.
2. Disconnect the Intrusion Sensor Receiver connector.
3. Disconnect the Intrusion Transceiver Module connector.
4. Turn the ignition on.
5. Measure the voltage of the (G946) Sensor Ground circuit in the Intrusion Sensor Receiver connector.
Is there any voltage present?
Yes
- Repair the (G946) Sensor Ground circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST. See: Verification Tests/Body Verification Test
No
- Go To 3
