Logic Flow Chart
Check Condition <DTC No.P3016-16>
  • Power drive unit (FEMCU) power supply voltage is 8.0 volts or more.
Check Condition <DTC No.P30A1-16>
  • Power drive unit (GCU) power supply voltage is 8.0 volts or more.
Check Condition <DTC No.P3018-16>
  • Power drive unit (VCU) power supply voltage is 8.0 volts or more.
Judgment Criterion
  • Detected IGBT driver power supply voltage malfunction switch is ON (When the IGBT driver power supply voltage is less than 10 volts, the voltage malfuncition switch turns on) for 0.12 seconds.

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.
