54Dd-CHARGING TIME IS LONGER THAN USUAL, OR CHARGING DOES NOT STOP.

Inspection Procedure 10: Charging Time is Longer than Usual, or Charging does not Stop.

COMMENTS ON TROUBLE SYMPTOM

The cause is assumed to be low or high temperature environment when charging, or use of an extension cable.

PROBABLE CAUSES

The excessive load to 12 volts power supply (Excessive power use due to electrical components)
Use of an extension cable.
The AC power supply (supply side) is failed.
The internal temperature of the on board charger/ DC-DC converter increases.

DIAGNOSIS

Required Special Tools

STEP 1. Check the 12 volts power supply.

Is the electrical component (12 volts power supply) used?

Turn OFF the electrical component (12 volts power supply).

Go to Step 2

STEP 2. Check the AC power supply.

Has the extension cable ever been used before?

Directly connect the charging cable with the AC power supply.

Go to Step 3

STEP 3. Using scan tool (M.U.T.-IIISE), check on board charger/DC-DC convertor data list item 37: Pilot signal (Duty ratio).

Set scan tool (M.U.T.-III) to the BMU data list for item 37 Pilot signal (Duty ratio) (Refer to )

OK: 8 - 97 % (Charging cable connected)

Is the check result normal?

Go to Step 4

Check the power supply system for home use.

STEP 4. Check the power supply voltage of the power supply system for home use.

Check whether the power supply voltage of the power system for home use is lower than the normal voltage.

OK: 90 - 254 volts

Is the check result normal?

Go to Step 5

Check the power supply system for home use.

STEP 5. Check the trouble symptom.

Is the check result normal?

Check the overheating [Refer to GROUP 54Da - Symptom Chart - EV system overheat (water cooling system)

Intermittent malfunction (temporary noise mixing of the ordinary charge cable or temporary stop of the household charging facility).
