DESCRIPTION	Temperature temporarily increases depending on various external and environmental factors (Rear vehicle monitoring control module (LH)/(RH))
DETECTION CONDITION	• Temperature around rear vehicle monitoring control module is 85 °C {185 °F} or more.
POSSIBLE CAUSE	• Temperature temporarily increases depending on various external and environmental factors (Rear vehicle monitoring control module (LH)/(RH)) • Rear vehicle monitoring control module (LH) malfunction • Rear vehicle monitoring control module (RH) malfunction

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	VERIFY REAR VEHICLE MONITORING CONTROL MODULE INTERNAL TEMPERATURE • Access the following PIDs using the M-MDS to verify the rear vehicle monitoring control module internal temperature: (See PID/DATA MONITOR INSPECTION [REAR VEHICLE MONITORING SYSTEM].) ― INTNL_TMP_L ― INTNL_TMP_R • Is the PID value 85 °C {185 °F} or more? (See PID/DATA MONITOR TABLE [REAR VEHICLE MONITORING SYSTEM].)	Yes	Replace the malfunctioning rear vehicle monitoring control module (LH)/(RH), then go to the next step. (See REAR VEHICLE MONITORING CONTROL MODULE REMOVAL/INSTALLATION.)
1		No	Go to the next step.
2	PERFORM DTC INSPECTION AND VERIFY THAT MALFUNCTIONING PART IS REAR VEHICLE MONITORING CONTROL MODULE (LH) • Clear the DTC from rear vehicle monitoring control module using the M-MDS. (See CLEARING DTC [REAR VEHICLE MONITORING SYSTEM].) • Perform the rear vehicle monitoring control module DTC inspection using the M-MDS. (See DTC INSPECTION [REAR VEHICLE MONITORING SYSTEM].) • Is the same DTC present?	Yes	Replace the rear vehicle monitoring control module (LH), then go to the next step. (See REAR VEHICLE MONITORING CONTROL MODULE REMOVAL/INSTALLATION.)
2		No	Go to Step 4.
3	VERIFY TROUBLESHOOTING COMPLETED • Clear the DTC from rear vehicle monitoring control module using the M-MDS. (See CLEARING DTC [REAR VEHICLE MONITORING SYSTEM].) • Perform the rear vehicle monitoring control module DTC inspection using the M-MDS. (See DTC INSPECTION [REAR VEHICLE MONITORING SYSTEM].) • Is the same DTC present?	Yes	Replace the rear vehicle monitoring control module (RH), then go to the next step. (See REAR VEHICLE MONITORING CONTROL MODULE REMOVAL/INSTALLATION.)
3		No	Go to the next step.
4	VERIFY THAT NO OTHER DTCs ARE PRESENT • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [REAR VEHICLE MONITORING SYSTEM].)
4		No	DTC troubleshooting completed.
