position of seat for driver, and restores it with just one memory switch. Equipment for Power seat adjusting
beside Power seat ECU are input switch, four motors and sensors. According to input signal four motors adjusts
horizontal position, inclination of the back of a seat, height of seat and position of brake pedal. Sensors for each
motor detects position and delivers it to power seat ECU.
