  1. FRONT POWER SEAT CONTROL SYSTEM DESCRIPTION


    • The driver seat is equipped with slide, reclining, lifter, front vertical and lumbar support adjustment functions.

    • The passenger seat is equipped with slide, reclining, lifter and front vertical adjustment functions.

    • The memory system for the driver seat is provided as standard equipment.

  2. FUNCTION OF MAIN COMPONENT

    The following functions are available.

    Components Function
    Seat slide motor Receives a signal from the front power seat switch and slides seat forward and rearward.
    Seat reclining motor Receive a signal from the front power seat switch and tilts and reclines the seat.
    Seat front vertical motor Receive a signal from the front power seat switch and raises and lowers the front of the seat cushion vertically.
    Seat lifter motor Receive a signal from the front power seat switch and raises and lowers the seat cushion vertically.
    Seat position sensor Is built into each power seat motor and sends position data to the position control ECU so that the ECU can detect the seat position at all times.
    Seat control switch

    Based on the switches operated, seat adjuster signals are input into the position control ECU and the seat is adjusted accordingly (for Driver Side).

    Directly sends seat adjuster signals to each power seat motor (for Passenger Side).
    Seat memory switch

    When the SET switch and memory switch are pressed simultaneously, a signal is input to the main body ECU and the seat position is recorded.

    Then, when the memory switch is pressed, a signal is input to the main body ECU and the seat position changes according to memory.

  3. SYSTEM OPERATION

    The front power seat functions which can be adjusted with power seat motors and/or memorized are shown in the chart below.
