Diagnostic Procedure

Step	Inspection		Action
1	INSPECT RVM WARNING INDICATOR LIGHT (RH) CONNECTOR CONDITION • Switch the ignition off. • Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 1.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [MZR 1.6].) • Disconnect the RVM warning indicator light (RH) connector. • Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. • Is the connector normal?	Yes	Go to the next step.
1		No	Repair or replace the connector, then go to Step 6.
2	INSPECT REAR VEHICLE MONITORING CONTROL MODULE (RH) CONNECTOR CONDITION • Disconnect the rear vehicle monitoring control module (RH) connector. • Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. • Is the connector normal?	Yes	Go to the next step.
2		No	Repair or replace the connector, then go to Step 6.
3	INSPECT FOR SHORT TO POWER SUPPLY IN RVM WARNING INDICATOR LIGHT (RH) CIRCUIT • Verify that the rear vehicle monitoring control module (RH) and RVM warning indicator light (RH) connectors are disconnected. • Reconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 1.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [MZR 1.6].) • Switch the ignition ON (engine off or on). • Measure the voltage at the following terminals (wiring harness-side): ― RVM warning indicator light (RH) terminal G ― RVM warning indicator light (RH) terminal H • Is the voltage 0 V?	Yes	Go to the next step.
3		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: • Rear vehicle monitoring control module (RH) terminal I—RVM warning indicator light (RH) terminal G • Rear vehicle monitoring control module (RH) terminal H—RVM warning indicator light (RH) terminal H If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has a short to power supply. Go to Step 6.
4	INSPECT RVM WARNING INDICATOR LIGHT (RH) • Inspect the RVM warning indicator light (RH). (See OUTER MIRROR GLASS INSPECTION.) • Is the RVM warning indicator light (RH) normal?	Yes	Go to the next step.
4		No	Replace the RVM warning indicator light (RH), then go to Step 6. (See OUTER MIRROR GLASS REMOVAL.) (See OUTER MIRROR GLASS INSTALLATION.)
5	INSPECT FOR OPEN CIRCUIT IN RVM WARNING INDICATOR LIGHT (RH) CIRCUIT • Verify that the rear vehicle monitoring control module (RH) and RVM warning indicator light (RH) connectors are disconnected. • Switch the ignition off. • Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 1.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [MZR 1.6].) • Inspect for continuity between the following terminals (wiring harness-side): ― Rear vehicle monitoring control module (RH) terminal I—RVM warning indicator light (RH) terminal G ― Rear vehicle monitoring control module (RH) terminal H—RVM warning indicator light (RH) terminal H • Is there continuity?	Yes	Go to the next step.
5		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: • Rear vehicle monitoring control module (RH) terminal I—RVM warning indicator light (RH) terminal G • Rear vehicle monitoring control module (RH) terminal H—RVM warning indicator light (RH) terminal H If there is a common connector: • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit. • Repair or replace the malfunctioning part. If there is no common connector: • Repair or replace the wiring harness which has an open circuit. Go to the next step.
6	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Always reconnect all disconnected connectors. • Reconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 1.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [MZR 1.6].) • Clear the DTC for the rear vehicle monitoring control module using the M-MDS. (See CLEARING DTC [REAR VEHICLE MONITORING SYSTEM].) • Illuminate the RVM warning indicator light (RH) using the simulation item WRN_IND_R. (See ACTIVE COMMAND MODES INSPECTION [REAR VEHICLE MONITORING SYSTEM].) • Retrieve the rear vehicle monitoring control module DTCs using the M-MDS. (See DTC INSPECTION [REAR VEHICLE MONITORING SYSTEM].) • Is the same DTC displayed?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the rear vehicle monitoring control module (RH). (See REAR VEHICLE MONITORING CONTROL MODULE REMOVAL/INSTALLATION.) Go to the next step.
6		No	Go to the next step.
7	VERIFY IF OTHER DTCs DISPLAYED • Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [REAR VEHICLE MONITORING SYSTEM].)
7		No	DTC troubleshooting completed.
