LIGHTING SYSTEM


  1. FUNCTION OF MAIN COMPONENTS

    Component Function
    Main Body ECU (Multiplex Network Body ECU) Receives various signals and illuminates the daytime running lights.
    Semiconductor PWR Integration ECU Supplies power to the daytime running lights.

    Headlight Dimmer Switch Assembly


    • Light Control Switch

    		 Outputs a light control switch position signal to the main body ECU (multiplex network body ECU).
    Instrument Panel Junction Block Assembly Receives the ignition signal and transmits it to the main body ECU (multiplex network body ECU).
    Parking Brake Switch Assembly Outputs a parking brake operation signal to the main body ECU (multiplex network body ECU).

  2. SYSTEM CONTROL


    1. Operating Condition


      1. The daytime running lights illuminate when the following conditions are met.
