id091400819400

1. Disconnect the negative battery cable.

2. Remove the intruder sensor cover. (See INTRUDER SENSOR COVER REMOVAL/INSTALLATION.)

3. Measure the intruder sensor terminal voltage using the short wiring harness connector in the position shown in the figure.

  Note
  • If the terminal voltage is not as indicated in the table, inspect the short wiring harness connector for continuity. (See Continuity Inspection Of Short Wiring Harness Connector.) If the short wiring harness connector is normal, inspect the parts under “Inspection items”.
    ― If the system does not work properly even though the parts or related wiring harnesses do not have any malfunction, replace the intruder sensor.

Terminal Voltage Table (Reference)

Terminal | Signal name | Connected to | Measurement condition | Voltage (V) | Inspection item (s)
--- | --- | --- | --- | --- | ---
B | GND | Body ground | Under any condition | 1.0 or less | Ground
C | DATA | Theft-deterrent control module | Terminal used for communication therefore determination based on terminal voltage inspection not possible.
D | Power supply | BCM | Under any condition | B+ | • BCM • ROOM 15 A fuse

Continuity Inspection Of Short Wiring Harness Connector

1. Verify that the continuity between the short wiring harness connector terminals is as indicated in the table.

  • If the continuity is not as indicated in the table, replace the short wiring harness connector.
