1.M.U.T.-IIISE other DTC check
Check whether the DTC, which has the higher priority than this DTC, is set. (Refer to DTC Inspection Priority Chart).
Is the DTC set?
Troubleshoot the set DTC (Refer to DIAGNOSTIC TROUBLE CODE CHART). Then,
 
2.M.U.T.-IIISE other system DTC
Check whether the PHEV-ECU sets the DTC related to the radiator fan.
Is the DTC set?
Troubleshoot the set DTC (Refer to PHEV-ECU – DIAGNOSTIC TROUBLE CODE CHART DIAGNOSTIC TROUBLE CODE CHART). Then,
 
3.Check of the generator resolver circuit
Check the generator resolver circuit (Refer to RESOLVER CIRCUIT INSPECTION).
Is the check result normal?
Repair or replace the faulty part. Then,
 
4.Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle OBD-II DRIVE CYCLE.
(2) Check the DTC.
Is the DTC set?
Replace the power drive unit (Refer to POWER DRIVE UNIT REMOVAL AND INSTALLATIONPOWER DRIVE UNIT REMOVAL AND INSTALLATION). Then, go to .
The trouble can be an intermittent malfunction (Refer to General Information - How to Use Troubleshooting/Inspection Service Points, How to Cope with Intermittent Malfunctions HOW TO COPE WITH INTERMITTENT MALFUNCTIONS).
 
5.Test the OBD-II drive cycle.
