Judgement Criterion
  • The overvoltage of the output current is detected.

FAIL-SAFE AND BACKUP FUNCTION



  • The charge is stopped.

PROBABLE CAUSES



  • Short circuit or harness damage in high voltage circuits between on board charger/DC-DC converter and drive battery, or loose connector contact.
  • The on board charger/DC-DC converter is failed

DIAGNOSIS PROCEDURE


danger When high voltage system components are served, be sure to pull service plugs to shut down high voltage (Refer to ).
danger When pulling service plugs, wear the specified protective equipment (Refer to ).

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


Q. Is the diagnosis code of PHEV-ECU system stored?

Check PHEV-ECU system (Refer to ).
Go to Step 2.

STEP 2. Check of short circuit and damage in P line and N line between on board charger/DC-DC converter connector and drive battery connector.


danger When high voltage system components are served, be sure to pull service plugs to shut down high voltage before serving (Refer to ).
danger When pulling service plugs, wear the specified protective equipment (Refer to ).

Q. Is the check result normal?
