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 To 2
No
- DTC is not active at this time. Test complete.
- Perform the BODY VERIFICATION TEST. See: Verification Tests/Body Verification Test
2. INTRUSION SENSOR TRANSMITTER
1. Disconnect the Intrusion Sensor Transmitter connector.
NOTE: Check connectors - Clean/repair as necessary.
2. Connect a known good Intrusion Sensor Transmitter.
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 3
No
- Replace the original Intrusion Sensor Transmitter.
- Perform the BODY VERIFICATION TEST. See: Verification Tests/Body Verification Test
3. CHECK THE (A645) INTRUSION TRANSMITTER SENSOR SIGNAL WIRE FOR A SHORT TO (G945) SENSOR GROUND
2010 Jeep Truck Grand Cherokee SRT-8 V8-6.1L Page 51
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 (A645) Intrusion Transmitter Sensor Signal circuit to the (G945) Sensor Ground circuit in the Intrusion
Sensor Transmitter connector.
Is the resistance below 5.0 ohms?
Yes
- Repair the (A645) Intrusion Transmitter Sensor Signal circuit for a short to the (G945) Sensor Ground circuit.
- Perform the BODY VERIFICATION TEST. See: Verification Tests/Body Verification Test
No
- Replace the Intrusion Transceiver Module.
- Perform the BODY VERIFICATION TEST. See: Verification Tests/Body Verification Test
