KEY WARNING CHIME (WITHOUT INTELLIGENT KEY) : System Description

INFOID:0000000005256304

With the key inserted into the key switch, and the ignition switch in the OFF or ACC position, when driver's

door is opened, the warning chime will sound.

• BCM detects key inserted into the ignition switch, and sends key warning signal to combination meter with

CAN communication line. 

• When combination meter receives key warning signal, it sounds warning chime.

KEY WARNING CHIME (WITHOUT INTELLIGENT KEY) : System Description

INFOID:0000000005256305

COMBINATION METER

• The buzzer for warning chime system is installed in the combination meter.

• The buzzer sounds when the combination meter receives a buzzer output signal from each unit.

BCM

BCM receives signals from various units and transmits a buzzer output signal to the combination meter with

CAN communication line if it judges that the warning buzzer should be activated.

Unit

Description

Combination meter

Receives key warning signal from BCM via CAN communication line and sounds the buzzer.

BCM

Judges the key warning condition from the door switch signal received from the front door switch 
LH, and the key switch signal received from the key switch. It then transmits a buzzer output signal 
to the combination meter via CAN communication line if necessary.

Front door switch LH

Transmits door switch signal to BCM.

Key switch

Transmits key switch signal to BCM.

DIAGNOSIS SYSTEM (METER)

Diagnosis Description

INFOID:0000000005511852

SELF-DIAGNOSIS MODE

The following items can be checked during Combination Meter Self-Diagnosis Mode.

• Gauge sweep and present gauge values.

• Illuminates all odometer/trip meters and A/T indicator segments.

• Illuminates all micro controlled lamps/LEDs regardless of switch position.

• Displays estimated present battery voltage.

• Displays seat belt buckle switch LH status.

OPERATION PROCEDURE

NOTE:

• Once entered, combination meter self-diagnosis mode will function with the ignition switch in ON or START.

Combination meter self-diagnosis mode will exit upon turning the ignition switch to OFF or ACC. 

• If the diagnosis function is activated with trip A displayed, the mileage on trip A is reset to 0000.0. (Trip B

operates the same way.)

To initiate combination meter self-diagnosis mode, refer to the following procedure.

1. Turn the ignition switch ON, while pressing the odometer/trip meter switch for 5 - 8 seconds. When the

diagnosis function is activated, the odometer/trip meter will display tESt.

NOTE:

Check combination meter power supply and ground circuit when self-diagnosis mode of combination meter

does not start. Refer to 

MWI-29, "COMBINATION METER : Diagnosis Procedure"

. Replace combination

meter if normal. Refer to 

MWI-96, "Removal and Installation"

.

1.

CHECK FUSES

Check for blown combination meter fuses.

Is the inspection result normal?

YES

>> GO TO 2

NO

>> If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse.

2.

POWER SUPPLY CIRCUIT CHECK

1. Disconnect combination meter connector M24.

2. Check voltage between combination meter harness connector

M24 terminals 3, 16 and ground.

Is the inspection result normal?

YES

>> GO TO 3

NO

>> Check harness for open between combination meter and fuse.

3.

GROUND CIRCUIT CHECK

1. Turn ignition switch OFF.

2. Check continuity between combination meter harness connector

M24 terminals 13, 23 and ground.

Is the inspection result normal?

YES

>> Inspection End.

NO

>> Check ground harness.
