Diagnostic Test

INTERMITTENT DTC
1. With the scan tool, erase the current Intrusion Transceiver Module DTCs.
2. Turn the ignition off.
3. Arm the VTSS and wait 1 minute.
4. Disarm the VTSS and turn the ignition on.
  Does the scan tool display the same DTC?
  
  Yes
  - Go To step 2
  No
  - The condition that caused this symptom is currently not present. Inspect the related wiring harness for a possible intermittent condition. Look for any chafed, pierced, pinched or partially broken wires.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .

1. Disconnect the Front Intrusion Sensor connector.
2. Using a 12-volt test light connected to ground, check the (A415) Fused B(+) circuit in the Intrusion Sensor connector.
  Does the test light illuminate brightly?
  
  Yes
  - Go To step 3
  No
  - Repair the (A415) Fused B+ circuit for an open.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .

1. Using a 12-volt test light connected to 12-volts, check the (Z970) Ground circuit at the Intrusion Sensor connector.
  Does the test light illuminate brightly?
  
  Yes
  - Go To step 4
  No
  - Repair the (Z907) Ground circuit for an open.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
INTRUSION SENSOR

1. The Front Intrusion Sensor connector is disconnected.
2. Measure the voltage of the (D122) LIN Bus circuit at the Intrusion Sensor connector with the key on and off.
3. Observe the voltage displayed on the voltmeter.
  Is the voltage between 1 and 12 volts?
  
  Yes
  - Replace the Intrusion Sensor in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - Go To step 5
(D122) LIN BUS CIRCUIT OPEN

1. Disconnect the Intrusion Transceiver Module harness connector.
2. Measure the resistance of the (D122) LIN Bus circuit between the Intrusion Transceiver Module and the Intrusion Sensor connector.
  Is the resistance below 3.0 ohms?
  
  Yes
  - Replace the Intrusion Transceiver Module in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - Repair the (D122) LIN Bus circuit for an open.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
