Code No. P1D19: PFC Circuit Output Voltage Abnormal (high voltage),
Code No. P1D20: PFC Circuit Output Voltage Abnormal (low voltage),
Code No. P1D21: PFC Circuit Output Voltage Abnormal (overvoltage)




TROUBLE JUDGEMENT


Check Condition
  • While the on board charger is allowed to be charged from the PHEV-ECU.
Judgement Criterion
    <Code No. P1D19>

    • The PFC output voltage is high.
    <Code No. P1D20>

    • The PFC output voltage is low.
    <Code No. P1D21>

    • The overvoltage of the PFC internal voltage is detected.

FAIL-SAFE AND BACKUP FUNCTION



  • The charge is stopped.

PROBABLE CAUSE



  • The on board charger/DC-DC converter is failed.

DIAGNOSIS PROCEDURE


STEP 1. M.U.T.-III diagnosis code


Q. Is the diagnosis code stored?

Replace the on board charger/DC-DC converter.
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
