1. Remove the trunk box. (See TRUNK BOX REMOVAL/INSTALLATION.)

2. Remove the theft-deterrent siren with the connector connected.

3. Measure the theft-deterrent siren terminal voltage using the short wiring harness connector in the position shown in the figure.

  Note
  • The theft-deterrent siren cannot be connected to a tester due to its water-resistance processing, therefore the short wiring harness connector is used for measuring the terminal voltage.
  • 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 theft-deterrent siren.

Terminal Voltage Table (Reference)

ac9wzw00001925

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

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.
