Code No. 15: Power Factor Correction (PFC) Circuit Temperature Abnormal

TROUBLE JUDGMENT

Check Conditions

When the charging cable is connected.
The on board charger control power supply voltage is more than 8 V.

or

While the electric motor switch is turned ON with the M.U.T.-III connected.
The on board charger control power supply voltage is more than 8 V.

Judgement Criterion

For more than 2 seconds, the power factor improvement circuit (PFC) temperature sensor is more than 115° C.

FAIL-SAFE AND BACKUP FUNCTION

The charge is stopped.

PROBABLE CAUSES

There is not enough coolant.
The water pump is failed.
The radiator fan is failed.
The temperature sensor installed in the on board charger is failed.

DIAGNOSIS PROCEDURE

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

Q. Is diagnosis code of EV-ECU system set?

	Check EV-ECU system (Refer to ).

	Go to Step 2 .

STEP 2. Check the coolant.

note

If the coolant largely decreases, check whether the coolant leakage exists or not. Repair it if necessary.

Check on coolant (Refer to GROUP 14 - On-vehicle Service - Coolant Check ).

Q. Is the check result normal?

	Go to Step 3 .

	Replace or supply the coolant.

STEP 3. M.U.T.-III actuator test

Refer to the Actruator Test Reference Table of the EV-ECU, .

Item 3: Water pump drive
Item 4: Radiator fan 1 drive
Item 5: Radiator fan 2 drive
Item 9: Water pump drive 2

Q. Is the check result normal?

	Go to Step 4 .

	Go to the check procedures for the diagnosis code for the actuator which has an abnormal drive (Refer to ).

STEP 4. M.U.T.-III diagnosis code

Q. Is the diagnosis code set?

	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 ).
