  1. FUNCTION OF MAIN COMPONENTS

    Component Function
    Headlight ECU Sub-assembly RH Receives daytime running light control signals and illuminates the daytime running lights.
    Headlight ECU Sub-assembly LH
    Main Body ECU (Multiplex Network Body ECU) Receives various signals and transmits the daytime running light control signal.
    Steering Sensor Sends the light control switch position signal to the main body ECU (multiplex network body ECU).
    Turn Signal Switch Light Control Switch Sends the light control switch position signal to the steering sensor.
    Automatic Light Control Sensor Detects the ambient light level and transmits a signal to the main body ECU (multiplex network body ECU).
    Parking Brake ECU Assembly Sends the parking brake operation signal to the main body ECU (multiplex network body ECU).
    ECM Sends the engine speed signal to the main body ECU (multiplex network body ECU).
    Central Gateway ECU (Network Gateway ECU) Relays the signal between the CAN communication lines.

  2. SYSTEM CONTROL


    1. Operating Condition


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


        • The engine switch is on (IG).

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

        • The light control switch is in the, AUTO position (and the taillights are not turned on via the automatic light control system).

        • The parking brake is released

  3. FUNCTION


    1. The daytime running light system is designed to automatically illuminate the Light Emitting Diode (LED) lights during the daytime to keep the vehicle highly visible to other vehicles.

    2. The daytime running light system can be turned on and off using the customization function. For details, refer to the Repair Manual.
