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
| Component | Function | |
|---|---|---|
| Position control ECU and switch assembly (driver seat) | Based on the switch operation, seat adjuster signals are input to the position control ECU and switch assembly (driver seat) to adjust the seat accordingly. | |
| Front seat adjuster assembly (driver seat) | Slide motor | Receives a signal from the position control ECU and switch assembly (driver seat), and slides the seat forward and rearward. |
| Front vertical motor | Receives a signal from the position control ECU and switch assembly (driver seat), and raises and lowers the front of the seat cushion. | |
| Lifter motor | Receives a signal from the position control ECU and switch assembly (driver seat), and raises and lowers the seat cushion. | |
| Position sensor | Built into the slide motor and lifter motor and sends position data to the position control ECU and switch assembly (driver seat) so that it can detect the position at all times. | |
| Front seatback frame sub-assembly (driver seat) | Reclining motor | Receives a signal from the position control ECU and switch assembly (driver seat), and tilts the seatback forward and rearward. |
| Inner limit switch assembly (Front seatback edge protector) | Detects the condition of the reclining remote control lever sub-assembly and sends a signal to the position control ECU and switch assembly (driver seat). | |
| Outer limit switch assembly (Front seatback edge protector) | Detects the condition of the front seatback frame sub-assembly and sends a signal to the position control ECU and switch assembly (driver seat). | |
| Lumbar support adjuster assembly (driver seat) | Receives a signal from the front lumbar power seat switch and operates the built-in motor to adjust the lumbar support. | |
| Seat memory switch (driver door)* | 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 outer mirror control ECU assembly (driver door) sends the signals so that the seat position can be stored. Then, when a seat memory switch (driver door) is pressed, a signal is sent to the outer mirror control ECU assembly (driver door) and the seat position changes according to memory. |
|
| Front lumbar power seat switch | Operates the motor built into the lumbar support adjuster assembly (driver seat) according to switch operation. | |

| Position control ECU and switch assembly (front passenger seat) | Based on the switch operation, seat adjuster signals are input to the position control ECU and switch assembly (front passenger seat) to adjust the seat accordingly. | |
| Front seat adjuster assembly (front passenger seat) | Slide motor | Receives a signal from the position control ECU and switch assembly (front passenger seat), and slides the seat forward and rearward. |
| Front vertical motor | Receives a signal from the position control ECU and switch assembly (front passenger seat), and raises and lowers the front of the seat cushion. | |
| Lifter motor | Receives a signal from the position control ECU and switch assembly (front passenger seat), and raises and lowers the seat cushion. | |
| Position sensor | Built into the slide motor and lifter motor and sends position data to the position control ECU and switch assembly (front passenger seat) so that it can detect the position at all times. | |
| Front seatback frame sub-assembly (front passenger seat) | Reclining motor | Receives a signal from the position control ECU and switch assembly (front passenger seat), and tilts the seatback forward and rearward. |
| Inner limit switch assembly (Front seatback edge protector (front passenger seat)) | Detects the condition of the reclining remote control lever sub-assembly and sends a signal to the position control ECU and switch assembly (front passenger seat). | |
| Outer limit switch assembly (Front seatback edge protector (front passenger seat)) | Detects the condition of the front seatback frame sub-assembly and sends a signal to the position control ECU and switch assembly (front passenger seat). | |
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 | - |
The seat memory switch (driver door) sends memory switch information to the outer mirror control ECU assembly (driver door). 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 and switch assembly (driver seat) via CAN. As a result, the seat position is memorized.*
