Logic Flow Chart <Judgment Criterion A>
Logic Flow Chart <Judgment Criterion B>
Check Condition A
  • Power drive unit (FEMCU) power supply voltage is 8.0 volts or more.
  • IGBT status: ON
Judgment Criterion A
  • The number of times that the IGBT driver power current high malfunction switch is ON* is three times or more.
Check Condition B
  • Power drive unit (FEMCU) power supply voltage is 8.0 volts or more.
  • IGBT status: OFF
Judgment CriterionB
  • The IGBT driver power current high malfunction switch is ON* for 0.4 seconds or more.
note* :
When the current between the emitter and the collector will be more than 800A of IGBT, FEMCU current-high switch turns on.
When the current between the emitter and the collector will be more than 420A of IGBT, GCU current-high switch turns on.
When the current between the emitter and the collector will be more than 640A of IGBT, VCU current-high switch turns on.

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 front motor 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 front motor cable (three phase line) with the specified torque (Refer to POWER DRIVE UNIT REMOVAL AND INSTALLATION). Then,
 
3.Visually check the front motor 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 front motor cable (three phase line).
Is the check result normal?
Replace the front motor (Refer to MOTOR (ELECTRIC MOTOR UNIT) 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 front motor
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 front motor (Refer to CHECK ON INSULATION RESISTANCE).
Is the check result normal?
Replace the front motor (Refer to MOTOR (ELECTRIC MOTOR UNIT) 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 front motor (Refer to MOTOR (ELECTRIC MOTOR UNIT) REMOVAL AND INSTALLATION). Then,
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).
 
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.
(2) Check the DTC.
Is the DTC set?
Retry the troubleshooting.
The procedure is complete.
