      Driver Front Passenger
      Power Control The fore-and-aft slide, reclining, cushion slide, front vertical, rear vertical, lumbar support and leg support can be adjusted using the power seat switch. X X
      Memory Memory The memory function can memorize 3 different seat positions. X X
      Recall The recall function can recall 3 different memorized seat positions. X X
      Memory Call The memory call function, which utilizes the key IDs of the transmitter, is used to memorize and retrieve the optimal driving positions for a person possessing the key. X -
      Seat Slide Away The seat slide away function automatically slides the seat rearward, achieving an easier access to get off the vehicle. X -
      The seat slide away function automatically returns the seat to the original position before starting the vehicle. X -

      • X: Equipped

      • -: Not equipped

    2. The memory function works in combination with the following systems, ensuring usability and enabling easy entering or exiting of the vehicle.

      System Outline
      Outside Rear View Mirror System The outer mirror control ECU memorizes the outside rear view mirror positions and recalls them when all conditions are met.
      Steering Column System The multiplex tilt and telescopic ECU memorizes the steering column position and recalls it when all conditions are met.

  3. CONSTRUCTION


    1. Leg Support Adjustment


      1. A leg support adjustment function is provided in order to deal with a wide range of driver heights. The length of the cushion pad front edge can be adjusted.

      2. Adjustment is operated through a link and rod connected to the motor, which extends and contracts the cushion pad.

  4. OPERATION


    1. Seat Position Detection Method


      1. A pulse generation circuit in position control ECU converts the current pulsations that are generated by the rotation of the motor into pulse signals. These signals are then picked up in order to detect the seat position.

  5. DIAGNOSIS


    1. The position control ECU has a diagnosis function. It stores a record of any power seat control system failures in its memory in the form of Diagnostic Trouble Codes (DTCs).

    2. The position control ECU outputs malfunction data, 5-digit DTCs, to the intelligent tester.

    3. The 5-digit DTCs can be read after connecting the intelligent tester to the DLC3. For details, refer to the Repair Manual.
