REVERSE WARNING CHIME : System Description

INFOID:0000000009188783

DESCRIPTION

• The BCM receives shift position signal (reverse range) from TCM via CAN communication.
• The BCM detects reverse warning chime based on the received signal and transmits the buzzer output sig-

nal to combination meter via CAN communication.

• The combination meter receives the buzzer output signal from BCM via CAN communication and sounds the

warning buzzer.

COMBINATION METER : Diagnosis Procedure

INFOID:0000000009188786

1.

CHECK FUSES

Check that the following fuses are not blown:

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace the fuse with a new one after repairing the applicable circuit.

2.

CHECK POWER SUPPLY CIRCUIT

Check the voltage between the combination meter harness connector terminals and the ground. 

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair the harness between the fuse and the combination meter. 

3.

CHECK GROUND CIRCUIT

1.

Turn the ignition switch OFF.

2.

Disconnect the combination meter connector.

3.

Check for continuity between the combination meter harness connector terminals and the ground. 

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Repair the harnesses or connectors.
