id0903z7994700

Description

Possible Causes

―  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)

Diagnostic Procedure

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	•  Implement the instrument cluster simulation ALARM using the M-MDS, and activate the warning alarm. •  Is the warning alarm activated?	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].)
