System Description
- FRONT POWER SEAT CONTROL SYSTEM DESCRIPTION
- The power seat is standard equipment for the front seats.
- A memory system is provided for the front seats as standard equipment.
- FUNCTION OF MAIN COMPONENT
The following functions are available.
COMPONENT FUNCTION TABLEComponents Function Power seat motor assy (slide motor) Receives signal from position control ECU, motor operates, and seat slides forward and rearward. Power seat motor assy (reclining motor) Receives signal from position control ECU, motor operates, and seat tilts and reclines. Power seat motor assy (slide motor) Receives signal from position control ECU, motor operates, and seat cushion slides. Power seat motor assy (front vertical motor) Receives signal from position control ECU, motor operates, and seat front vertical raises and lowers. Power seat motor assy (lifter motor) Receives signal from position control ECU, motor operates, and seat rear vertical raises and lowers. Lumbar support adjuster motor Receives signal from position control ECU, motor operates, and lumbar support can be adjusted. Position control sensor (reclining, lifter, slide, front vertical control) Is built in each front seat adjuster and sends seat position data to position control ECU so that it can detect seat positions at all times. Front power seat switch (reclining, lifter, slide, front vertical) Based on switches operated, seat adjuster signals are input into position control ECU and seat is adjusted accordingly. Lumbar front power seat switch Based on switches operated, seat adjuster signals are input into position control ECU and seat is adjusted accordingly. Seat memory switch (set switch, memory switch) When set switch and memory switch are pressed simultaneously, SET, 1 or 2 switch is input to multiplex network door ECU front and seat position is recorded. Then, when memory switch is pressed, SET, 1 or 2 switch is input to multiplex network door ECU front and seat position changes according to memory. - SYSTEM OPERATION
The front power seat's adjustment and position memory are shown in SYSTEM OPERATION TABLE .
