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, clearance lights, taillights and license plate lights.

  2. LIGHT AUTO TURN-OFF SYSTEM (for LHD)

    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 lights, taillights, clearance 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.

    Switch Condition Outline
    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

    The taillights, clearance lights, license plate lights and rear fog lights will remain on.

  3. LIGHT AUTO TURN-OFF SYSTEM (except LHD)


    1. 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, taillights, clearance lights and license plate lights).

    2. When all of the following conditions are met, the low beam headlights, high beam headlights, front fog lights, taillights, clearance lights and license plate lights turn off:


      • The ignition switch is turned from ON to off.

      • The low beam headlights, high beam headlights, front fog lights, taillights, clearance lights and license plate lights are on.

      • The driver door is opened.

  4. DAYTIME RUNNING LIGHT SYSTEM

    The daytime running light system is designed to automatically illuminate the daytime running 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) and semiconductor pwr integration ECU. The main body ECU (multiplex network body ECU) transmits a turn on signal to the semiconductor pwr integration ECU, which illuminates the daytime running lights.

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


      • The ignition switch is ON.

      • The engine speed signal is input (engine running).

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

      • The parking brake switch is off.

  5. FOLLOW ME HOME SYSTEM (for LHD)


    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.

  6. DOOR MIRROR FOOT LIGHT SYSTEM (w/ Door Mirror Foot Light)


    1. General


      • The door mirror foot light system consists primarily of the fade-in/fade-out function and timer illumination function.

      • This system is controlled by the outer mirror control ECU assembly for each mirror and main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) sends door mirror foot light on/off demand signals to the outer mirror control ECU assembly. According to various information, the outer mirror control ECU assembly performs fade-in/fade-out control of the door mirror foot lights.

    2. The door mirror foot light system has the following control functions:

      Function Outline

      Door Lock-linked

      When either of the following conditions is met, the lights that operate turn off:


      • All doors are locked when all doors are closed and any door is unlocked.

      • All doors are locked again when all doors are closed and locked.
      Engine Switch-linked*

      When the following condition is met, the lights that operate turn off:


      • The engine switch is on (IG).
      Delay

      When approximately 15 seconds elapse after any of the following conditions are met, the lights that operate turn off:


      • An actuation area-linked function is used.

      • The door unlock-linked function is active.

      • Any door is opened and then closed.
