5HB

1.  Remove the following parts:

(1)  Rear scuff plate (passenger's side) (See REAR SCUFF PLATE REMOVAL/INSTALLATION.)

(2)  Rear seat cushion (See REAR SEAT CUSHION REMOVAL/INSTALLATION.)

(3)  Rear seat back (See REAR SEAT BACK REMOVAL/INSTALLATION.)

(4)  Trunk end trim (See TRUNK END TRIM REMOVAL/INSTALLATION.)

(5)  Trunk side trim (passenger's side) (See TRUNK SIDE TRIM 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 Terminal Voltage Table (Reference).)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	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.
