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

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.

―  Open circuit in wiring harness between IG1 relay and rear vehicle monitoring control module (RH) terminal G

―  C/U IG1 15 A fuse damage, burnt out

―  Poor ground (looseness, disengagement)

―  Rear vehicle monitoring control module malfunction (internal malfunction)

―  Open circuit in wiring harness between IG1 relay and rear vehicle monitoring control module (LH) terminal G

―  C/U IG1 15 A fuse damage, burnt out

―  Open circuit in wiring harness between rear vehicle monitoring control module (LH) terminal E and ground

―  Poor ground (looseness, disengagement)

―  Rear vehicle monitoring control module malfunction (internal malfunction)

―  RVM warning indicator light malfunction

―  Open or short circuit in wiring harness between rear vehicle monitoring control module (RH) and RVM warning indicator light

―  Rear vehicle monitoring control module (RH) internal malfunction (RVM warning indicator light illumination circuit disabled)

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

Diagnostic Procedure

Step	Inspection		Action
1	DETERMINE IF MALFUNCTION CAUSE IS RVM INDICATOR LIGHT (GREEN) OR RVM WARNING INDICATOR LIGHT ILLUMINATION CIRCUIT •  Switch the ignition ON (engine off or on). •  Verify RVM indicator light (green) condition. •  Does the RVM indicator light (green) illuminate?	Yes	Go to Step 3.
		No	Go to the next step.
2	DETERMINE IF MALFUNCTION CAUSE IS REAR VEHICLE MONITORING CONTROL MODULE OR INSTRUMENT CLUSTER RELATED •  Illuminate all the indicator lights and warning lights in the instrument cluster using the active command modes WL+IL in the M-MDS. (See ACTIVE COMMAND MODES INSPECTION [INSTRUMENT CLUSTER].) •  Does the RVM indicator light (green) illuminate?	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.)
3*	DETERMINE IF MALFUNCTION CAUSE IS REAR VEHICLE MONITORING CONTROL MODULES OR RVM WARNING INDICATOR LIGHTS •  Inspect the following: RVM warning indicator light (RH) related: ―  RVM warning indicator light (RH) ―  Wiring harness between RVM warning indicator light (RH) terminal G and rear vehicle monitoring control module (RH) terminal I ―  Wiring harness between RVM warning indicator light (RH) terminal H and rear vehicle monitoring control module (RH) terminal H RVM warning indicator light (LH) related: ―  RVM warning indicator light (LH) ―  Wiring harness between RVM warning indicator light (LH) terminal G and rear vehicle monitoring control module (RH) terminal B ―  Wiring harness between RVM warning indicator light (LH) terminal H and rear vehicle monitoring control module (RH) terminal F •  Is any malfunction verified?	Yes	•  Refer to the wiring diagram and verify whether or not there is a mid-connector between the RVM warning indicator light and rear vehicle monitoring control module. If there is a mid-connector ―  Determine the malfunctioning part by inspecting the mid-connector and the terminal for corrosion, damage, or pin disconnection, and the mid-wiring harness for a a open circuit or short to ground. ―  Repair or replace the wiring harness which has a malfunction. If there is no mid-connector ―  Repair or replace the wiring harness which has a malfunction.
		No	Go to the next step.
4*	INSPECT REAR VEHICLE MONITORING CONTROL MODULE (LH) POWER SUPPLY SYSTEM •  Switch the ignition ON (engine off or on). •  Measure the voltage at rear vehicle monitoring control module (LH) terminal G. •  Is the voltage B+?	Yes	Go to the next step.
		No	•  Inspect the C/U IG1 15 A fuse. If the fuse is burned out: •  Inspect and repair the wiring harness between the C/U IG1 15 A fuse and rear vehicle monitoring control modules (RH/LH) terminal G for a short circuit to the ground system. If the fuse is not damaged or burned out: •  Refer to the wiring diagram and verify whether or not there is a mid-connector between IG relay terminal 1B and rear vehicle monitoring control modules (RH/LH) terminal G. If there is a mid-connector •  Determine the malfunctioning part by inspecting the mid-connector and the terminal for corrosion, damage, or pin disconnection, and the mid-wiring harness for a open circuit. •  Repair or replace the wiring harness which has a malfunction. If there is no mid-connector •  Repair or replace the wiring harness which has a malfunction.
5*	INSPECT REAR VEHICLE MONITORING CONTROL MODULE (LH) GROUND SYSTEM •  Switch the ignition off (LOCK). •  Disconnect the rear vehicle monitoring control module (LH) connector. •  Verify continuity between rear vehicle monitoring control module (LH) vehicle wiring harness-side connector terminal E and ground. •  Is there continuity?	Yes	Replace the rear vehicle monitoring control module (LH). (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.
