Caution / Notice / Hint

NOTE:
  • Before troubleshooting, make sure that the customize setting "DRL Function" is set to "ON".
  • If the headlight ECU sub-assembly LH has been replaced, it is necessary to synchronize the vehicle information and initialize the headlight ECU sub-assembly LH.

    Refer to REGISTRATION [10/2023 - ]

  • When replacing the headlight ECU sub-assembly LH, always replace it with a new one. If a headlight ECU sub-assembly LH which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
