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.Check of the high-voltage terminal (three phase line) of power drive unit
danger
  • Carry out the check on the high-voltage circuit while reading carefully the precautions on handling a high-voltage vehicle.
  • Wear the specified protection equipment during the check.
Check whether the high-voltage terminal of the generator cable (three phase line) is connected to the power drive unit with the specified torque (Refer to POWER DRIVE UNIT REMOVAL AND INSTALLATION).
Is the check result normal?
Install the generator cable (three phase line) with the specified torque (Refer to POWER DRIVE UNIT REMOVAL AND INSTALLATION). Then,
 
3.Visually check the generator cable.
danger
  • Carry out the check on the high-voltage circuit while reading carefully the precautions on handling a high-voltage vehicle.
  • Wear the specified protection equipment during the check.
Visually check that there is no burnout, damage, foreign material on the generator cable (three phase line).
Is the check result normal?
Replace the generator (Refer to GENERATOR REMOVAL AND INSTALLATION). Then,
 
4.Check of the insulation resistance of the power drive unit
danger
  • Carry out the check on the high-voltage circuit while reading carefully the precautions on handling a high-voltage vehicle.
  • Wear the specified protection equipment during the check.
Check the insulation resistance of the power drive unit (Refer to CHECK ON INSULATION RESISTANCE).
Is the check result normal?
Replace the power drive unit (Refer to POWER DRIVE UNIT REMOVAL AND INSTALLATION). Then,
 
5.Check of the insulation resistance of the generator
danger
  • Carry out the check on the high-voltage circuit while reading carefully the precautions on handling a high-voltage vehicle.
  • Wear the specified protection equipment during the check.
Check the insulation resistance of the generator (Refer to CHECK ON INSULATION RESISTANCE).
Is the check result normal?
Replace the generator (Refer to GENERATOR REMOVAL AND INSTALLATION). Then,
 
6.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 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).
 
7.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 generator (Refer to GENERATOR REMOVAL AND INSTALLATION). Then,
The procedure is complete.
 
8.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.
