id0903z7014600

Note

• If there is any vehicle malfunction complaint lodged by a customer, perform FOREWORD [REAR VEHICLE MONITORING SYSTEM] malfunction diagnosis according to the troubleshooting procedure.

Description

• Rear vehicle monitoring warning alarm does not sound even though rear vehicle monitoring system recognizes a vehicle in detection area on side in which turn signal is operated or one entering blind-spot area from rear, and RVM warning indicator light is flashing.

Possible malfunction

Note

• The detection performance of the rear vehicle monitoring control module has limitations and the Rear vehicle monitoring system may not operate normally. For the detection performance limitations, refer to the [REAR VEHICLE MONITORING CONTROL MODULE] in the technical guide.

• Instrument cluster receives incorrect beeper sound request signal

― Instrument cluster malfunction

― Rear vehicle monitoring control module (LH) malfunction

Diagnostic Procedure

Step

Inspection

Action

1

INSPECT ALARM

•  Implement the instrument cluster simulation ALARM using the M-MDS, and activate the warning alarm.
(See ACTIVE COMMAND MODES INSPECTION [INSTRUMENT CLUSTER].)

•  Is the warning alarm activated?

Yes

Go to the next step.

No

Replace the instrument cluster.

(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

2

DETERMINE IF MALFUNCTION CAUSE IS BUZZER SOUND RELATED CIRCUIT

•  Implement the rear vehicle monitoring system active command modes Buzzer item using the M-MDS.
(See ACTIVE COMMAND MODES INSPECTION [REAR VEHICLE MONITORING SYSTEM].)

•  Does the buzzer sound?

Yes

Go to the next step.

No

Replace the rear vehicle monitoring control module (LH).

(See REAR VEHICLE MONITORING CONTROL MODULE REMOVAL/INSTALLATION.)

3

VERIFY RVM WARNING INDICATOR LIGHT ILLUMINATION CONDITION

•  Verify the illumination of the RVM warning indicator lights when the illumination conditions (vehicle speed of 30 km/h {19 mph} or more, turn signals off, and vehicle detected in blind-spot area or entering blind-spot area from rear) are satisfied.

•  Is the RVM warning indicator lights illumination normal?

Yes

Replace the rear vehicle monitoring control module (LH).

(See REAR VEHICLE MONITORING CONTROL MODULE REMOVAL/INSTALLATION.)

No

Go the symptom troubleshooting procedure, "RVM warning indicator light does not illuminates while under the illumination conditions".

(See RVM WARNING INDICATOR LIGHT DOES NOT ILLUMINATE UNDER ILLUMINATION CONDITIONS [REAR VEHICLE MONITORING SYSTEM].)
