WIPER AND WASHER SYSTEM


  1. FUNCTION OF MAIN COMPONENTS


    1. The raindrop sensing function consists of the following parts:

      Component Function
      Windshield Wiper Switch Assembly Setting this switch to AUTO will cause the raindrop sensing function to operate and adjust its sensitivity.
      Rain Sensor Senses raindrops when the windshield wiper switch assembly is in AUTO, and sends signals to the windshield wiper relay assembly.
      Windshield Wiper Relay Assembly Receives operation signals from the rain sensor and inputs them into the front wiper motor and link assembly.
      Front Wiper Motor and Link Assembly Operates the wiper in accordance with the signals from the rain sensor, when the windshield wiper switch assembly is in AUTO.
      Combination Meter Assembly Receives signals from the speed sensor and sends the vehicle speed signal to the windshield wiper relay assembly.

  2. SYSTEM CONTROL


    1. Raindrop Sensing Function


      1. The raindrop sensing function controls the wiping timing in accordance with the amount of raindrops when the windshield wiper switch assembly is in AUTO position.

      2. This control is effected by the rain sensor based on the amount of raindrops and input signals from the windshield wiper relay assembly.

      3. An illuminance detection function is provided to automatically change the raindrop sensitivity according to day or night.

    2. Washer-linked Wiper Function


      1. When the windshield wiper switch assembly is in off or AUTO position and the washer switch is turned on for approximately 0.5 seconds or more, the wipers start on LO at the same time as the washer fluid is sprayed.
