LIGHTING SYSTEM SYSTEM DESCRIPTION


  1. AUTOMATIC LIGHT CONTROL SYSTEM

    When the light control switch is in the AUTO position, the automatic light control system detects ambient light levels and controls the low beam headlights, parking lights, taillights and license plate lights.

  2. LIGHT AUTO TURN-OFF SYSTEM

    The light auto turn-off system is used to prevent the exterior lights from being accidentally left on (low beam headlights, high beam headlights, front fog lights, rear fog light, taillights, parking lights and license plate lights.

    The lights that will turn off will vary as shown in the table below, according to the position of the light control switch.

    Light control switch in AUTO position While the exterior lights are turned on, this control automatically turns them off when the ignition switch is turned from ON to off.
    Light control switch in tail or head position

    While the exterior lights are turned on, this control automatically turns off only the low beam headlights, high beam headlights and the front fog lights when the ignition switch is turned from ON to off.

    Tech Tips

    Taillights, parking lights, license plate lights and rear fog light remain on.

  3. DAYTIME RUNNING LIGHT SYSTEM

    The daytime running light system is designed to automatically illuminate the daytime running lights (high-intensity parking lights) during the daytime to make the vehicle more visible to other vehicles.


    • This system is controlled by the main body ECU (multiplex network body ECU).

    • There are 2 LED type parking light circuits in each headlight. One is for a conventional low-intensity parking light that illuminates with the taillights, and the other is for the high-intensity parking light that is used for the DRL system.

    • This system is enabled when the following conditions are met:


      • Ignition switch is ON.

      • Engine speed signal is input (engine running).

      • Light control switch is in the off or AUTO position (and the low beam headlights are not turned on via the automatic light control system).

      • Parking brake switch is off.

  4. LED HEADLIGHT SYSTEM


    1. General

      LED headlights are used to provide efficient, maintenance free lighting. Compared to halogen or HID headlights, even if an LED headlight is used for a long time, the reduction of brightness over its lifetime is less. In addition, there is no possibility of an LED having an open circuit because of vibration.

    2. Function of Main Components

      Light Control ECU

      • Turns on the LEDs immediately when the light control switch is turned to the head position.

      • Regulates the current flowing into the LEDs to a specified level to prevent the light from getting brighter and dimmer due to voltage variation.

      • Transmits fail signals to the headlight swivel ECU assembly when a malfunction occurs in the LED headlight system.
      Combination Meter Assembly Displays a warning message to inform the driver when the light control ECU detects a malfunction in this system.
      Headlight Swivel ECU Assembly

      • Receives fail signals from the light control ECU when a malfunction occurs in the LED headlight system, and transmits the signals to the combination meter assembly.

      • Stores Diagnostic Trouble Codes (DTCs) when the system malfunctions.

  5. FOLLOW ME HOME SYSTEM


    1. The follow me home system is designed to illuminate the low beam headlights for approximately 30 seconds after the vehicle is parked.


      1. This system is controlled by the main body ECU (multiplex network body ECU).

      2. This system is enabled when the following conditions are met:


        • The ignition switch is off.

        • The light control switch is in the off or AUTO position.

        • The light control switch is pulled to flash the headlights once.
