METER BUZZER CIRCUIT

Description

INFOID:0000000009945521

• The buzzer for warning chime system is installed in the combination meter.
• The combination meter sounds the alarm buzzer based on the signals transmitted from various units.

Component Function Check

INFOID:0000000009945522

1.

CHECK OPERATION OF METER BUZZER

1.

Select “BUZZER” of “BCM” on CONSULT.

2.

Perform “LIGHT WARN ALM” of “Active Test”.

Does meter buzzer beep?

YES

>> INSPECTION END

NO

>> GO TO 2.

2.

CHECK COMBINATION METER INPUT SIGNAL

Select the “Data Monitor” for the “METER/M&A” and check the “BUZZER” monitor value.

Is the inspection result normal?

YES

>> Replace combination meter.

NO

>> Replace BCM. Refer to 

BCS-88, "Removal and Installation"

 (with Intelligent Key system) or 

BCS-

155, "Removal and Installation"

 (without Intelligent Key system).

Diagnosis Procedure
