FRONT POWER SEAT CONTROL SYSTEM DESCRIPTION
The driver seat is equipped with slide, reclining, lifter, front vertical, and lumbar support adjustment functions.
The front passenger seat is equipped with slide, reclining, lifter and front vertical functions.
The memory call function uses the key ID code of the key to memorize and recall the appropriate driving position for each individual who possesses a master key or sub key.
FUNCTION OF MAIN COMPONENT
*: for Standard Seat Type
| Component | Function | |
|---|---|---|
| Position control ECU assembly | Based on the switch operation, seat adjuster signals are input to the position control ECU assembly to adjust the seat accordingly. | |
| Front power seat switch | Operates the motor according to switch operation. | |
| Front seat adjuster assembly | Slide motor | Receives a signal from the position control ECU assembly, and slides the seat forward and rearward. |
| Power seat tilt motor assembly | Receives a signal from the position control ECU assembly, and raises and lowers the front of the seat cushion. | |
| Power seat lifter motor assembly | Receives a signal from the position control ECU assembly, and raises and lowers the seat cushion. | |
| Position sensor | Built into the slide motor, lifter motor and tilt motor and sends position data to the position control ECU assembly so that it can detect the position at all times. | |
| Front seatback frame sub-assembly | Reclining motor | Receives a signal from the position control ECU assembly, and tilts the seatback forward and rearward. |
| Position sensor | Built into the reclining motor and sends position data to the position control ECU assembly so that it can detect the position at all times. | |
| Front headrest adjuster assembly* | Headrest motor | Receives a signal from the position control ECU assembly, and slides the headrest up and down. |
| Position sensor | Built into the headrest motor and sends position data to the position control ECU assembly so that it can detect the position at all times. | |
| Front seatback edge protector (inner limit switch assembly) | Detects the condition of the reclining remote control lever sub-assembly and sends a signal to the position control ECU assembly . | |
| Front seatback edge protector (outer limit switch assembly) | Detects the condition of the front seatback frame sub-assembly and sends a signal to the position control ECU assembly . | |
| Lumbar support adjuster assembly | 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 front multiplex network door ECU 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 front multiplex network door ECU and the seat position changes according to memory. |

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 and Memory | Power |
| Headrest* | Power and Memory | Power |
*: for Standard Seat Type
The seat memory switch sends memory switch information to the front multiplex network door ECU (for Driver Seat). 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 assembly (for Driver Seat) via CAN. As a result, the seat position is memorized.
