  2. FUNCTION OF MAIN COMPONENT 
    FOR DRIVER SEAT

    Component Function
    Position control ECU and switch assembly LH Based on the switch operation, seat adjuster signals are input to the position control ECU and switch assembly LH to adjust the seat accordingly.
    Front seat adjuster assembly LH Slide motor Receives a signal from the position control ECU and switch assembly LH, and slides the seat forward and rearward.
    Front vertical motor Receives a signal from the position control ECU and switch assembly LH, and raises and lowers the front of the seat cushion.
    Lifter motor Receives a signal from the position control ECU and switch assembly LH, and raises and lowers the seat cushion.
    Position sensor Built into the slide motor and lifter motor and sends position data to the position control ECU and switch assembly LH so that it can detect the position at all times.
    Separate type front seatback spring assembly (driver seat) Reclining motor Receives a signal from the position control ECU and switch assembly LH, and tilts the seatback forward and rearward.
    Inner limit switch assembly (Front seatback edge protector) Detects the condition of the reclining remote control lever sub-assembly and sends a signal to the position control ECU and switch assembly LH.
    Outer limit switch assembly (Front seatback edge protector) Detects the condition of the separate type front seatback spring assembly and sends a signal to the position control ECU and switch assembly LH.
    Lumbar support adjuster assembly LH Receives a signal from the front lumbar power seat switch and operates the built-in motor to adjust the lumbar support.
    Seat memory switch* If the seat memory SET switch is being pressed when one of the M1, M2 or M3 seat memory switches is pressed, or if one of the M1, M2 or M3 switches is pressed within 3 seconds of pressing the SET switch, the outer mirror control ECU assembly (driver door) sends the signals so that the seat position can be stored.
    Then, when a seat memory switch is pressed, a signal is sent to the outer mirror control ECU assembly (driver door) and the seat position changes according to memory.
    Front lumbar power seat switch Operates the motor built into the lumbar support adjuster assembly LH according to switch operation.

    FOR FRONT PASSENGER SEAT

    Component Function
    Position control ECU and switch assembly RH Based on the switch operation, seat adjuster signals are input to the position control ECU and switch assembly RH to adjust the seat accordingly.
    Front seat adjuster assembly RH Slide motor Receives a signal from the position control ECU and switch assembly RH, and slides the seat forward and rearward.
    Front vertical motor Receives a signal from the position control ECU and switch assembly RH, and raises and lowers the front of the seat cushion.
    Lifter motor Receives a signal from the position control ECU and switch assembly RH, and raises and lowers the seat cushion.
    Position sensor Built into the slide motor and lifter motor and sends position data to the position control ECU and switch assembly RH so that it can detect the position at all times.
    Separate type front seatback spring assembly (front passenger seat) Reclining motor Receives a signal from the position control ECU and switch assembly RH, and tilts the seatback forward and rearward.
    Inner limit switch assembly (Front seatback edge protector (front passenger seat)) Detects the condition of the reclining remote control lever sub-assembly and sends a signal to the position control ECU and switch assembly RH.
    Outer limit switch assembly (Front seatback edge protector (front passenger seat)) Detects the condition of the separate type front seatback spring assembly and sends a signal to the position control ECU and switch assembly RH.
  3. SYSTEM OPERATION 

    The front power seat functions which can be operated with the power seat motors and memorized are shown below.

    Seat Function Driver Seat Front Passenger Seat
    Slide Power and Memory Power
    Reclining Power and Memory Power
    Front Vertical Power and Memory Power
    Lifter Power and Memory Power
    Lumbar Support adjustment Power -

    The seat memory switch sends memory switch information to the outer mirror control ECU assembly (driver door). Then the information is sent to the main body ECU (multiplex network body ECU) via CAN and then an instruction to memorize the seat position is sent to the position control ECU and switch assembly LH via CAN. As a result, the seat position is memorized.*
