|
Lumbar support motor
| Receives a signal from the power seat switch assembly and adjusts the lumbar support adjuster.
|
Seat position sensor
| Is built into each power seat motor and sends position data to the position control ECU so that the ECU can detect the seat position at all times.
|
Front power seat switch
| Based on the switches operated, seat adjuster signals are input into the position control ECU and the seat is adjusted accordingly (for driver side).
Directly sends seat adjuster signals to each power seat motor (for passenger side).
|
Power seat switch assembly
| Directly sends seat adjuster signals to the lumbar support motor.
|
Seat memory switch
| When the SET switch and memory switch are pressed simultaneously, a signal is input to the main body ECU and the seat position is recorded.
Then, when the memory switch is pressed, a signal is input to the main body ECU and the seat position changes according to memory.
|
The front power seat functions which can be adjusted with power seat motors and/or memorized are shown in the chart below.
For the memory function, the memory switch operation signal is first sent from the main body ECU to the position control ECU via the CAN communication line. Then, either the seat position is recorded in memory or a previously recorded seat position is recalled.
