No.8 REAR VEHICLE MONITORING WARNING CHIME DOES NOT SOUND WHILE RVM WARNING INDICATOR LIGHT IS FLASHING [REAR VEHICLE MONITORING SYSTEM]

8	Rear vehicle monitoring warning chime does not sound while RVM warning indicator light is flashing
DESCRIPTION	• Rear vehicle monitoring warning chime 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 CAUSES	• Instrument cluster receives incorrect beeper sound request signal ― Instrument cluster malfunction ― Communication error between rear vehicle monitoring control module (RH) and instrument cluster ― Rear vehicle monitoring control module (RH) malfunction ― Communication error between rear vehicle monitoring control modules (RH and LH) (Detected results are not transmitted from LH to RH side)

Rear vehicle monitoring warning chime does not sound while RVM warning indicator light is flashing

DESCRIPTION

• Rear vehicle monitoring warning chime 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 CAUSES

• Instrument cluster receives incorrect beeper sound request signal

― Instrument cluster malfunction

― Communication error between rear vehicle monitoring control module (RH) and instrument cluster

― Rear vehicle monitoring control module (RH) malfunction

― Communication error between rear vehicle monitoring control modules (RH and LH) (Detected results are not transmitted from LH to RH side)

Step	Inspection	Action
1	VERIFY DTCs • Retrieve DTCs from the rear vehicle monitoring system and instrument cluster using the M-MDS. (See DTC INSPECTION [REAR VEHICLE MONITORING SYSTEM].) (See DTC INSPECTION [INSTRUMENT CLUSTER].) • Are any DTCs displayed?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [REAR VEHICLE MONITORING SYSTEM].) (See DTC TABLE [INSTRUMENT CLUSTER].)
No	Go to the next step.
2	• Sound all the warning alarms in the instrument cluster using the simulation function ALARM in the M-MDS instrument cluster. • Does the rear vehicle monitoring warning chime sound?	Yes	Go to the next step.
No	Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
3	DETERMINE IF MALFUNCTION CAUSE IS BUZZER SOUND RELATED CIRCUIT • Turn the rear vehicle monitoring system PID BUZZER (rear vehicle monitoring warning chime) on and off using the M-MDS simulation function. • Does the chime sound?	Yes	Go to the next step.
No	Replace the rear vehicle monitoring control module (RH). (See REAR VEHICLE MONITORING CONTROL MODULE REMOVAL/INSTALLATION.)
4	VERIFY RVM WARNING INDICATOR LIGHT ILLUMINATION CONDITION • Verify the illumination of the RVM warning indicator lights when the illumination conditions (vehicle speed above 60 km/h {37 mph}, 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 (RH). (See REAR VEHICLE MONITORING CONTROL MODULE REMOVAL/INSTALLATION.)
No	Go to the symptom troubleshooting procedure,“No.5 RVM warning indicator light does not illuminate while under illumination conditions”. (See No.5 RVM WARNING INDICATOR LIGHT DOES NOT ILLUMINATE UNDER ILLUMINATION CONDITIONS [REAR VEHICLE MONITORING SYSTEM].)

Step

Inspection

Action

VERIFY DTCs

• Retrieve DTCs from the rear vehicle monitoring system and instrument cluster using the M-MDS.

(See DTC INSPECTION [REAR VEHICLE MONITORING SYSTEM].)

(See DTC INSPECTION [INSTRUMENT CLUSTER].)

• Are any DTCs displayed?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [REAR VEHICLE MONITORING SYSTEM].)

(See DTC TABLE [INSTRUMENT CLUSTER].)

Go to the next step.

• Sound all the warning alarms in the instrument cluster using the simulation function ALARM in the M-MDS instrument cluster.

• Does the rear vehicle monitoring warning chime sound?

Yes

Go to the next step.

Replace the instrument cluster.

(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

DETERMINE IF MALFUNCTION CAUSE IS BUZZER SOUND RELATED CIRCUIT

• Turn the rear vehicle monitoring system PID BUZZER (rear vehicle monitoring warning chime) on and off using the M-MDS simulation function.

• Does the chime sound?

Yes

Go to the next step.

Replace the rear vehicle monitoring control module (RH).

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

VERIFY RVM WARNING INDICATOR LIGHT ILLUMINATION CONDITION

• Verify the illumination of the RVM warning indicator lights when the illumination conditions (vehicle speed above 60 km/h {37 mph}, 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 (RH).

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

Go to the symptom troubleshooting procedure,“No.5 RVM warning indicator light does not illuminate while under illumination conditions”.

(See No.5 RVM WARNING INDICATOR LIGHT DOES NOT ILLUMINATE UNDER ILLUMINATION CONDITIONS [REAR VEHICLE MONITORING SYSTEM].)
