THEFT-DETERRENT SIREN AND TILT SENSOR INSPECTION

id091400822600

Note

• The tilt sensor are built into the theft-deterrent siren.

1. Disconnect the negative battery cable.

2. Remove the following parts:

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

(2) Trunk side trim (RH) (See TRUNK SIDE TRIM REMOVAL/INSTALLATION.)

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

Note

• The tilt sensor 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 5HB.)If the short wiring harness connecter 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 tilt sensor (theft-deterrent siren).

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.
