      Replacement of the headlight light control ECU sub-assembly LH Vehicle information registration for the headlight light control ECU sub-assembly LH
      Initialization of the headlight light control ECU sub-assembly LH

    • A new headlight light control ECU sub-assembly LH cannot operate until the vehicle information is registered.

    • After replacing the headlight light control ECU sub-assembly LH, it is necessary to register the vehicle information and then perform initialization.

    • Even if the headlight light control ECU sub-assembly RH is replaced with a new one, vehicle information registration and initialization are not necessary.

    • Vehicle information registration must be performed with the main body ECU (multiplex network body ECU) and ECM connected via CAN communication.
