System Description
- FRONT POWER SEAT CONTROL SYSTEM DESCRIPTION
- The driver seat and front passenger seat are equipped with slide, reclining, lifter, front vertical and lumbar support adjustment functions.
- The memory system for the front seats is optional. With the memory function, the position control ECU & switch performs the following: 1) controls the slide, reclining, lifter and front vertical motors; 2) memorizes the seat position; and 3) operates the seat restoring operation.
- The memory call function uses the key ID code of the key to memorize and reproduce the appropriate driving position for each individual who possesses a master key or sub key.
- FUNCTION OF MAIN COMPONENT
The following functions are available.
Components Function Power seat motor assembly (slide motor) Receives signal from position control ECU and motor operates to slide seat forward and rearward Power seat motor assembly (reclining motor) Receives signal from position control ECU and motor operates to tilt and recline seat Power seat motor assembly (front vertical motor) Receives signal from position control ECU and motor operates to raise and lower seat cushion front vertically Power seat motor assembly (lifter motor) Receives signal from position control ECU and motor operates to raise and lower seat cushion vertically Lumbar support adjuster motor Receives signal from lumbar front power seat switch and motor operates so that lumbar support can be adjusted Front power seat switch (reclining, lifter, slide, front vertical) Based on switches operated, seat adjuster signals are input into position control ECU to adjust seat accordingly Lumbar front power seat switch Based on switches operated, seat adjusts accordingly Seat memory switch LH (driver side) (SET switch, memory switch) When the M1, M2 or M3 switch is pressed while the SET switch being pressed, or M1, M2 or M3 switch is pressed within 3 seconds after the SET switch is pressed, a signal is input to multiplex network master switch and sent to position control ECU, which records seat position
When M1, M2 or M3 switch is pressed, signal is input to multiplex network master switch and sent to position control ECU, which changes seat position to recorded positionSeat memory switch RH (passenger side) (SET switch, memory switch) When the M1, M2 or M3 switch is pressed while the SET switch being pressed, or M1, M2 or M3 switch is pressed within 3 seconds after the SET switch is pressed, a signal is input to front multiplex network door ECU RH and sent to position control ECU, which records seat position
When M1, M2 or M3 switch is pressed, signal is input to multiplex network master switch and sent to position control ECU, which changes seat position to recorded position - SYSTEM OPERATION
The front power seat adjustment and position memory are shown in the chart below.

For the passenger side memory function, memory switch operation is first transferred from the front multiplex network door ECU RH to the position control ECU via the multiplex communication line. Then, either the seat position is recorded in memory or a previously recorded seat position is recalled.
