Seats: Description and Operation

Current is always applied from ECU-B fuse to TERMINAL SYSB of the seat position control ECU, from POWER fuse to TERMINAL +B of the seat position control ECU, and from STOP fuse to TERMINAL 2 of the stop light SW.
With the ignition SW turned ON, current flows from ECU-IG fuse to TERMINAL IG of the seat position control ECU and from the GAUGE fuse to TERMINAL 2 of the P position SW.

POWER SEAT OPERATION (DRIVER'S SEAT)
Current is always applied to TERMINAL SYSB and TERMINAL +B of the seat position control ECU so that seat position control ECU is always ready to operate.
When the power seat control SW is pushed to the "FRONT SLIDEPosition" side, a signal is input into TERMINAL SLDF of the seat position control ECU, the ECU operates and the current to TERMINAL +B of the seat position control ECU flows from TERMINAL SLD+ of the seat position control ECU to TERMINAL 1 of the power seat motor (Driver's seat slide control) to TERMINAL 2 to TERMINAL SLD- of the seat position control ECU to TERMINAL GND to GROUND, rotating the power seat motor so that the seat slides forward while the power seat control SW is being pressed.
To slide the driver's seat to the rear, pushing the power seat control SW to the "REAR SIDE Position" side, inputs a signal to TERMINAL SLDR of the seat position control ECU. This causes the current flowing from the ECU to the motor to flow from TERMINAL SLD- of the seat position control ECU to TERMINAL 2 of the power seat motor (Driver's seat slide control) to TERMINAL 1 to TERMINAL SLD+ of the seat position control ECU, flowing the reverse to front slide operation and causing the motor to rotate in reverse, so that the driver's seat moves to the rear.

The movement to other positions occurs similarly, so only the flow of current to each motor is shown:

FRONT VERTICAL CONTROL UP OPERATION
TERMINAL +B of the seat position control ECU to TERMINAL FRV+ to TERMINAL 1 of the power seat motor (Driver's seat front vertical control) to TERMINAL 2 to TERMINAL FRV- of the ECU to TERMINAL GND to GROUND.

FRONT VERTICAL CONTROL DOWN OPERATION
TERMINAL +B of the seat position control ECU to TERMINAL FRV- to TERMINAL 2 of the power seat motor (Driver's seat front vertical control) to TERMINAL 1 to TERMINAL FRV+ of the ECU to TERMINAL GND to GROUND.

REAR VERTICAL CONTROL UP OPERATION
TERMINAL +B of the seat position control ECU to TERMINAL RRV+ to TERMINAL 1 of the power seat motor (Driver's seat rear vertical control) to TERMINAL 2 to TERMINAL RRV- of the ECU to TERMINAL GND to GROUND.

REAR VERTICAL CONTROL DOWN OPERATION
TERMINAL +B of the seat position control ECU to TERMINAL RRV- to TERMINAL 2 of the power seat motor (Driver's seat rear vertical control) to TERMINAL 1 to TERMINAL RRV+ of the ECU to TERMINAL GND to GROUND.

RECLINING CONTROL FRONT OPERATION
TERMINAL +B of the seat position control ECU to TERMINAL RCL+ to TERMINAL 2 of the power seat motor (Driver's seat reclining control) to TERMINAL 1 to TERMINAL RCL- of the ECU to TERMINAL GND to GROUND.

RECLINING CONTROL REAR OPERATION
TERMINAL +B of the seat position control ECU to TERMINAL RCL- to TERMINAL 1 of the power seat motor (Driver's seat reclining control) to TERMINAL 2 to TERMINAL RCL+ of the ECU to TERMINAL GND to GROUND.

The number of turns of each motor (Amount of movement of each part of the seat) is detected by the position sensors and input to the ECU, making it possible to perform memory and return functions for the seat position using the seat memory switch.
