LIGHTING SYSTEM


  1. FUNCTION OF MAIN COMPONENTS

    Component Function
    Headlight ECU Sub-assembly RH Supplies power to the headlights and clearance lights.
    Headlight ECU Sub-assembly LH
    No. 3 Semiconductor Power Integration ECU Supplies power to the taillights and license plate lights.
    Turn Signal Switch Light Control Switch Sends the light control switch position signal to the steering sensor.
    Steering Sensor Sends the light control switch position signal to the main body ECU (multiplex network body ECU).
    Main Body ECU (Multiplex Network Body ECU) Receives various signals and illuminates the headlights, clearance lights, taillights and license plate lights.
    Automatic Light Control Sensor Detects the ambient light level and transmits a signal to the main body ECU (multiplex network body ECU).
    Front Door Courtesy Light Switch Assembly LH / RH Detects whether a door is open or closed and sends the signal to the main body ECU (multiplex network body ECU).
    Certification ECU (Smart Key ECU Assembly) Sends engine switch condition signals to the main body ECU (multiplex network body ECU).
    Radio Receiver Assembly Sends function customization information from the multi-display setting screen to the main body ECU (multiplex network body ECU).
    Multi-display Displays the settings screen.
    Central Gateway ECU (Network Gateway ECU) Relays the signal between the CAN communication lines.

  2. SYSTEM CONTROL


    1. Operating Condition


      1. The automatic light control system operates as follows:

        Function Outline
        Headlights and Taillights Turn On

        When all of the following conditions are met, the headlights, clearance lights, taillights and license plate lights automatically turn on:


        • The ambient light is dark or momentarily bright*.

        • The engine switch is on (IG).

        • The light control switch is in the AUTO position.
        Headlights and Taillights Turn Off When the ambient light is bright, the exterior lights automatically turn off.

        Tech Tips

        *: The sensitivity of the automatic light control sensor can be changed on the settings screen of the multi-display.
