LIGHTING SYSTEM


  1. FUNCTION OF MAIN COMPONENTS

    Component Function
    Headlight Assembly LH Headlight ECU Sub-Assembly LH

    • Receives signals from each ECU and sensor and illuminates the daytime running light.

    • Outputs a daytime running light illuminate signal to the headlight ECU sub-assembly LH.
    Headlight Assembly RH Headlight ECU Sub-Assembly RH Receives signals from the headlight ECU sub-assembly LH and illuminates the daytime running light.
    Main Body ECU (Multiplex Network Body ECU) Receives various signals and illuminates the daytime running lights.
    ECM The ECM sends a vehicle information signal via the CAN communication.
    Parking Brake ECU Assembly Outputs a parking brake operation signal to the main body ECU (multiplex network body ECU).
    Automatic Light Control Sensor Detects the ambient light level and transmits a signal to the main bodyECU (multiplex network body ECU).
    Headlight Dimmer Switch Assembly Light Control Switch Outputs a light control switch position 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.


        • The engine switch is on (IG).

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

        • The headlight dimmer switch assembly is in the off* or AUTO position (and the taillights are not turned on via the automatic light control system).

        • The parking brake is off.


          • *: Models with light control switch (off position)
