id0903z7014000

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

• The RVM indicator light (green) does not turn off even though the RVM switch turns off after the ignition is switched ON.

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.

• Rear vehicle monitoring control module (LH) does not recognize the RVM switch on/off status.

― RVM switch malfunction (stuck switch, internal malfunction)

― Rear vehicle monitoring control module (LH) malfunction

• Instrument cluster does not turn off RVM indicator light (green).

― Instrument cluster internal malfunction (RVM indicator light (green) illumination circuit disabled)

Diagnostic Procedure

Step

Inspection

Action

1^*

DETERMINE IF MALFUNCTION CAUSE IS RVM SWITCH OR RVM INDICATOR LIGHT (GREEN) RELATED

•  Monitor the rear vehicle monitoring system PIDs MAIN_SW using the M-MDS.
(See PID/DATA MONITOR INSPECTION [REAR VEHICLE MONITORING SYSTEM].)

•  Turn the RVM switch on and off.

•  Does the PID MAIN_SW monitoring value turn on and off according to the RVM switch operation?

Yes

Go to Step 3.

No

Go to the next step.

2

INSPECT RVM SWITCH

•  Inspect the RVM switch.
(See RVM SWITCH INSPECTION.)

•  Is the RVM switch normal?

Yes

Go to the next step.

No

Replace the RVM switch.

(See RVM SWITCH REMOVAL/INSTALLATION.)

3

DETERMINE IF MALFUNCTION CAUSE IS INSTRUMENT CLUSTER OR REAR VEHICLE MONITORING CONTROL MODULE (LH)

•  Turn off all the indicator lights and warning lights in the instrument cluster using the active command modes WL+IL of the M-MDS.
(See ACTIVE COMMAND MODES INSPECTION [INSTRUMENT CLUSTER].)

•  Does the RVM indicator light (green) turn off?

Yes

Replace the rear vehicle monitoring control module (LH).

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

No

Replace the instrument cluster.

(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
