1. GENERAL DESCRIPTION
When the power seat control switch is operated, a command signal is sent to the position control ECU and switch assembly (power seat control switch and ECU). The position control ECU and switch assembly (power seat control switch and ECU) then activates the appropriate seat motor as needed.
This memory system does not use a seat position sensor. The seat position is detected by counting pulses that are output when the motor turns. The position control ECU and switch assembly (power seat control switch and ECU) is designed so that a malfunction of the seat memory system will not interfere with seat control. The seat memory switch also sends signals to the position control ECU and switch assembly (power seat control switch and ECU) to memorize a given seat position. Two seat positions can be memorized. The seat memory switch is later used to send signals to the position control ECU and switch assembly (power seat control switch and ECU) to return the seat to either of the memorized positions.
2. FUNCTION OF MAIN COMPONENT (w/ MEMORY)
Components |
Function |
Seat slide motor | Slides the driver side seat back and forth based on signals from the position control ECU and switch assembly (power seat control switch and ECU). |
Seat reclining motor | Reclines the driver side seat back and forth based on signals from the position control ECU and switch assembly (power seat control switch and ECU). |
Seat front vertical motor | Moves the front part of the driver side seat cushion up and down based on signals from the position control ECU and switch assembly (power seat control switch and ECU). |
Seat lifter motor | Moves the driver side seat cushion up and down based on signals from the position control ECU and switch assembly (power seat control switch and ECU). This motor operates, and driver side seat rear vertical raises and lowers, and driver side seat rear vertical raises and lowers. |
Set switch Memory switch | When the set and memory switches are pressed simultaneously, SET, 1
or 2 switch signal is input to the
power window regulator switch assembly (power window master switch) and
sends the seat memory
switch signal via the multiplex communication system.
When only the memory switch is pressed, SET, 1 or 2 switch signal is input to power window regulator switch assembly (power window master switch) and driver side seat position changes according to memory. |
Lumbar support adjuster motor | Receives signal from lumber front power seat switch, motor operates, and lumber 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 and seat is adjusted accordingly |
Lumbar front power seat switch | Based on switches operated, seat is adjusted accordingly |
3. SYSTEM OPERATION
*: with Seat Position Memory System In the memory function, the memory switch operation signal is transferred from the outer mirror control ECU LH to the position control ECU and switch assembly (power seat control switch and ECU) via the multiplex communication line. Then, either the seat position is stored in memory or the previously stored seat position is recalled to set the appropriate seat position.
