DTC SET CONDITIONS
Logic Flow Chart <DTC P0E03, P0E02, P0E0B, P0E0A>
Check Conditions
  • Power drive unit (GCU) power supply voltage is 8 volts to 16 volts.
Judgment Criterion <DTC P0E03, P0E0B>
  • Change of the power drive unit (GCU) current sensor voltage is more than 4.7 volts (770 amperes) for 0.3 second.
Judgment Criterion <DTC P0E02, P0E0A>
  • Change of the power drive unit (GCU) voltage is less than 0.3 volt (-770 amperes) for 0.3 second.
Logic Flow Chart <DTC P0E01, P0E09>
Check Conditions <DTC P0E01, P0E09>
  • Power drive unit (GCU) power supply voltage is 8 volts to 16 volts.
  • The IGBT status of power drive unit (GCU) is off (Shutdown) or off to on.
Judgment Criterion <DTC P0E01, P0E09>
  • When the IGBT status of the power drive unit (GCU) is off (Shutdown), when a state where the power drive unit (GCU) current sensor voltage is at least 2.611 volts (39 amperes) and not more than 2.389 volts (-39 amperes) continues for 0.4 seconds.
  • When the IGBT status of the power drive unit (GCU) changes from off to on, when the power drive unit (GCU) current sensor voltage is at least 2.611 volts (39 amperes) and not more than 2.389 volts (-39 amperes).
 
 
OBD-II DRIVE CYCLE PATTERN
  • Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 1 .
 
 
PROBABLE CAUSES
Malfunction of the power drive unit [generator control unit (GCU)]
 
 
 
DIAGNOSIS
STEP 1. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 1 .
(2) Check the DTC.
Is the DTC set?
Replace the power drive unit (Refer to ). Then go to Step 2.
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points, - How to Cope with Intermittent Malfunctions ).
 
STEP 2. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 1 .
(2) Check the DTC.
Is the DTC set?
Retry the troubleshooting.
The inspection is complete.
