No.2 RVM INDICATOR LIGHT (GREEN) DOES NOT TURN OFF WHEN REAR VEHICLE MONITORING SYSTEM IS OFF [REAR VEHICLE MONITORING SYSTEM]

id0903z7994100

Description

Possible Causes

―  RVM switch malfunction (stuck switch, internal malfunction)

―  Open circuit in wiring harness between RVM switch terminal I and rear vehicle monitoring control module (RH) terminal D (L.H.D.)

―  Open circuit in wiring harness between RVM switch terminal C and rear vehicle monitoring control module (RH) terminal D (R.H.D.)

―  Open circuit in wiring harness between RVM switch terminal K and ground

―  RVM switch ground point looseness/disengagement

―  Rear vehicle monitoring control module (RH) malfunction

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

―  Rear vehicle monitoring control module (RH) internal malfunction (off-request signal is not output)

―  Instrument cluster internal malfunction (off-request signal is not received)

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

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*	DETERMINE IF MALFUNCTION CAUSE IS RVM SWITCH OR RVM INDICATOR LIGHT (GREEN) RELATED •  Monitor the rear vehicle monitoring system PID 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 6.
		No	Go to the next step.
3	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.)
4*	VERIFY IF MALFUNCTION CAUSE IS OPEN CIRCUIT IN RVM SWITCH SIGNAL-RELATED WIRING HARNESS •  Switch the ignition to off (LOCK). •  Disconnect the rear vehicle monitoring control module (RH) and RVM switch connectors. •  Verify the continuity between the rear vehicle monitoring control module (RH) terminal D and RVM switch terminal I by checking the continuity at the vehicle wiring harness-side connector. (L.H.D.) •  Verify the continuity between the rear vehicle monitoring control module (RH) terminal D and RVM switch terminal C by checking the continuity at the vehicle wiring harness-side connector. (R.H.D.) •  Is there continuity?	Yes	Go to the next step.
		No	Repair or replace the wiring harness for an open circuit.
5*	DETERMINE IF MALFUNCTION CAUSE IS OPEN CIRCUIT IN RVM SWITCH GROUND SYSTEM WIRING HARNESS OR REAR VEHICLE MONITORING CONTROL MODULE (RH) •  Leave the RVM switch connector disconnected. •  Verify the continuity between RVM switch terminal K and ground. •  Is there continuity?	Yes	Replace the rear vehicle monitoring control module (RH). (See REAR VEHICLE MONITORING CONTROL MODULE REMOVAL/INSTALLATION.)
		No	Inspect and repair the ground point for looseness, disengagement, or lifting. Inspect and repair the wiring harness for an open circuit.
6	DETERMINE IF MALFUNCTION CAUSE IS INSTRUMENT CLUSTER OR REAR VEHICLE MONITORING CONTROL MODULE (RH) •  Turn off all the indicator lights and warning lights in the instrument cluster using the simulation function WL+IL of the M-MDS instrument cluster. •  Does the RVM indicator light (green) turn off?	Yes	Replace the rear vehicle monitoring control module (RH). (See REAR VEHICLE MONITORING CONTROL MODULE REMOVAL/INSTALLATION.)
		No	Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
