Diagnostic Test
- TEST FOR INTERMITTENT CONDITION
- Turn the ignition on.
- With the scan tool, record and erase DTCs.
- Turn the ignition off and remove the key from the ignition.
- Close all doors and arm the VTSS and wait 1 minute.
- Disarm the VTSS turn the ignition on and wait 1 minute.
- With the scan tool, read DTCs.
Does the scan tool display this DTC as active?
Yes
- Go to Step 2.
No
- The conditions that caused this code to set are not present at this time. Using Figure as a guide, inspect the wiring and connectors.
- Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
- CHECK THE (A645) INTRUSION TRANSMITTER SENSOR SIGNAL CIRCUIT VOLTAGE Fig 1: Measuring Voltage Between Intrusion Sensor Signal Circuit & Intrusion Transmitter Sensor Ground Circuit

- Disconnect the Intrusion Sensor Transmitter connector.NOTE: Check connectors - Clean/repair as necessary.
- Turn the ignition on.
- With the scan tool actuate the Intrusion Sensor Transmitter.
- Measure the voltage between (A645) Intrusion Sensor Signal circuit and (G945) Intrusion Transmitter Sensor Ground circuit.
Is the voltage above 10.0 volts
Yes
- Go to Step 3.
No
- Go to Step 4.
- Disconnect the Intrusion Sensor Transmitter connector.
- CHECK THE INTRUSION SENSOR TRANSMITTER
- Turn the ignition is off.
- Install a known good Intrusion Sensor Transmitter.
- Turn the ignition on.
- With the scan tool erase DTCs.
- Turn the ignition off and remove the key from the ignition.
- Close all doors and arm the VTSS and wait 1 minute.
- Disarm the VTSS turn the ignition on and wait 1 minute.
- With the scan tool, read DTCs.
Does the scan tool display this DTC as active?
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
- Replace the original Intrusion Sensor Transmitter.
- Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
- CHECK THE (A645) INTRUSION TRANSMITTER SENSOR SIGNAL WIRE Fig 2: Measuring Resistance Of Intrusion Transmitter Sensor Signal Circuit Between Intrusion Sensor Transmitter Conn & Intrusion Transceiver Module Conn

- Turn the ignition is off.
- Disconnect the Intrusion Transceiver Module connector.
- Measure the resistance of the (A645) Intrusion Transmitter Sensor Signal circuit between the Intrusion Sensor Transmitter connector and the Intrusion Transceiver Module connector.
Is the resistance below 5.0 ohms?
Yes
- Repair the (A645) Intrusion Transmitter Sensor Signal circuit for an open.
- Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
No
- Go to Step 5.
- CHECK THE (G945) INTRUSION TRANSMITTER SENSOR GROUND WIRE FOR AN OPEN Fig 3: Measuring Resistance Of Intrusion Transmitter Sensor Ground Circuit From Intrusion Sensor Transmitter Conn To Intrusion Transceiver Module Conn

- Ensure Ignition is off.
- Measure the resistance of the (G945) Intrusion Transmitter Sensor Ground circuit from the Intrusion Sensor Transmitter connector to the Intrusion Transceiver Module connector.
Is the resistance below 5.0 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 (G945) Intrusion Transmitter Sensor Ground circuit for an open.
- Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
