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.
4. Close all doors and arm the VTSS and wait two minutes.
5. Disarm the VTSS turn the ignition on.
6. Turn the ignition on and with the scan tool, read DTCs.
Does the scan tool display B1A37-SECURITY TRANSMITTER SENSOR CIRCUIT LOW ?
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. See: Verification Tests/Body Verification Test
2. INTRUSION SENSOR TRANSMITTER
1. Turn the ignition off.
2. Disconnect the Intrusion Sensor Transmitter connector.
3. Turn the ignition on and with the scan tool, erase DTCs.
4. Turn the ignition off and remove the key from the ignition.
5. Close all doors and arm the VTSS and wait two minutes.
6. Disarm the VTSS turn the ignition on.
7. With the scan tool, read DTCs.
Does the scan tool display B1A41-SECURITY TRANSMITTER SENSOR CIRCUIT OPEN?
Yes
- Replace the Intrusion Sensor Transmitter.
- Perform the BODY VERIFICATION TEST. See: Verification Tests/Body Verification Test
No
- Go To 3
3. CHECK THE (A645) INTRUSION TRANSMITTER SENSOR SIGNAL CIRCUIT SHORT TO GROUND
2010 Jeep Truck Grand Cherokee SRT-8 V8-6.1L Page 42
1. Turn the ignition off.
2. Disconnect the Intrusion Transceiver Module connector.
3. Measure the resistance between ground and the (A645) Intrusion Transmitter Sensor Signal circuit at the Intrusion Transceiver Module
connector.
Is the resistance below 5.0 ohms?
Yes
- Repair the (A645) Intrusion Transmitter Sensor Signal circuit for a short to ground.
- 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
