DIAGNOSIS
Required Special Tools
  • MB991223: Wiring harness set
  • MB992006: Extra fine probe
STEP 1. Using scan tool (M.U.T.-IIISE), check on board charger/DC-DC converter data list.
  • Data List Reference Table (Refer to ).
    • Item No.38: PFC temperature
    • Item No.39: Inverter temperature 1
    • Item No.40: Inverter temperature 2
    • Item No.41: Inside temperature
Are the check result normal?
Go to Step 2.
Replace the on board charger/DC-DC converter (Refer to ).
 
STEP 2. Using scan tool (M.U.T.-IIISE), check whether the DTC is set again.
Is the DTC set?
