DTC SET CONDITIONS
Logic Flow Chart <Judgment Criterion A>
Logic Flow Chart <Judgment Criterion B>
Check Condition A
  • Power drive unit (VCU) 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 (VCU) 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.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,
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).
 
3.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.
