2.INTRUSION SENSOR TRANSMITTER

NOTE: Check connectors - Clean/repair as necessary.

Does the DTC reset?

Yes

Replace the original Intrusion Sensor Transmitter.
Perform BODY VERIFICATION TEST – VER 1 (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)

3.CHECK THE (A645) INTRUSION TRANSMITTER SENSOR SIGNAL WIRE FOR A SHORT TO (G945) SENSOR GROUND

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 BODY VERIFICATION TEST – VER 1 (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
