POWER SEAT (w/ DRIVING POSITION MEMORY)
CURRENT IS ALWAYS APPLIED FROM THE DOME FUSE TO TERMINAL SYSB OF THE POWER SEAT ECU, FROM DOOR FUSE TO
TERMINAL +B OF THE POWER SEAT ECU AND FROM STOP FUSE TO TERMINAL 2 OF THE STOP LIGHT SW.
WHEN THE IGNITION SW IS TURNED ON, CURRENT FLOWS FROM ECU±IG FUSE TO TERMINAL IG OF THE POWER SEAT ECU AND
FROM THE GAUGE FUSE TO TERMINAL 9 OF A/T INDICATOR SW.
POWER SEAT OPERATION (FOR DRIVER'S SEAT)
CURRENT IS ALWAYS APPLIED TO TERMINAL SYSB AND TERMINAL +B OF POWER SEAT ECU SO THAT THE POWER SEAT ECU IS
ALWAYS READY TO OPERATE.
WHEN THE POWER SEAT CONTROL SW IS PUSHED TO THE ªFRONT SIDE POSITIONº SIDE, A SIGNAL IS INPUT INTO TERMINAL
SLDF OF POWER SEAT ECU, THE ECU OPERATES AND THE CURRENT TO TERMINAL +B OF POWER SEAT ECU FLOWS FROM
TERMINAL SLD+ OF POWER SEAT ECU " TERMINAL 2 OF POWER SEAT MOTOR (FOR DRIVER'S SEAT SLIDE CONTROL) " MOTOR
TERMINAL 1 "TERMINAL SLD± OF POWER SEAT ECU "TERMINAL GND "GROUND, ROTATING THE POWER SEAT MOTOR SO
THAT THE SEAT SLIDES FORWARD WHILE THE POWER SEAT CONTROL SW IS BEING PRESSED.
TO SIDE THE DRIVER'S SEAT TO THE REAR, PUSHING THE POWER CONTROL SW TO THE ªREAR SLIDE POSITIONº SIDE, INPUTS A
SIGNAL TO TERMINAL SLDR OF POWER SEAT ECU. THIS CAUSES THE CURRENT FLOWING FROM THE ECU TO THE MOTOR TO
FLOW FROM TERMINAL SLD± OF POWER SEAT ECU " TERMINAL 2 OF POWER SEAT MOTOR (FOR DRIVER'S SEAT SLIDE
CONTROL) "MOTOR " TERMINAL 1 "TERMINAL SLD+ OF POWER SEAT 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 POWER SEAT ECU " TERMINAL FRV+ " TERMINAL 2 OF POWER SEAT MOTOR "MOTOR "TERMINAL 1 "
TERMINAL FRV± OF ECU " TERMINAL GND " GROUND .
FRONT VERTICAL CONTROL 'DOWN' OPERATION
TERMINAL +B OF POWER SEAT ECU " TERMINAL FRV± " TERMINAL 1 OF POWER SEAT MOTOR "MOTOR " TERMINAL 2 "
TERMINAL FRV+ OF ECU " TERMINAL GND " GROUND .
REAR VERTICAL CONTROL 'UP' OPERATION
TERMINAL +B OF POWER SEAT ECU " TERMINAL RRV+ " TERMINAL 2 OF POWER SEAT MOTOR "MOTOR " TERMINAL 1 "
TERMINAL RRV± OF ECU " TERMINAL GND " GROUND .
REAR VERTICAL CONTROL 'DOWN' OPERATION
TERMINAL +B OF POWER SEAT ECU " TERMINAL RRV± " TERMINAL 1 OF POWER SEAT MOTOR " MOTOR " TERMINAL 2 "
TERMINAL RRV+ OF ECU " TERMINAL GND " GROUND .
LUMBAR SUPPORT CONTROL 'FRONT' OPERATION
TERMINAL 7 OF POWER SEAT CONTROL SW " TERMINAL 4 OF LUMBAR SUPPORT SW " TERMINAL 1 " TERMINAL 11 OF POWER
SEAT CONTROL SW " TERMINAL 1 OF POWER SEAT MOTOR " MOTOR " TERMINAL 2 " TERMINAL 10 OF POWER SEAT
CONTROL SW " TERMINAL 2 OF LUMBAR SUPPORT SW "TERMINAL 3 "TERMINAL 12 OF POWER SEAT CONTROL SW "
GROUND .
LUMBAR SUPPORT CONTROL 'REAR' OPERATION
TERMINAL 7 OF POWER SEAT CONTROL SW " TERMINAL 4 OF LUMBAR SUPPORT SW " TERMINAL 2 " TERMINAL 10 OF POWER
SEAT CONTROL SW " TERMINAL 2 OF POWER SEAT MOTOR " MOTOR " TERMINAL 1 " TERMINAL 11 OF POWER SEAT
CONTROL SW " TERMINAL 1 OF LUMBAR SUPPORT SW "TERMINAL 3 "TERMINAL 12 OF POWER SEAT CONTROL SW "
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 DRIVING POSITION MEMORY AND RETURN SWITCH.
POWER WALK±IN OPERATION (FOR PASSENGER'S SEAT)
WALK±IN OPERATION
WHEN THE WALK±IN PEDAL IS DEPRESSED OR THE RECLINING HANDLE IS LIFTED UP, THE SEAT BACK RECLINES FULLY
FORWARD AND RECLINING LIMIT SWITCH NO. 2 OPERATES, SO A SIGNAL IS INPUT TO TERMINAL RFSW OF THE POWER SEAT ECU
" TERMINAL SLD+ " TERMINAL 1 OF THE POWER SEAT MOTOR (FOR PASSENGER'S SEAT SLIDE CONTROL) " MOTOR "
TERMINAL 2 " TERMINAL SLD± OF THE ECU "TERMINAL GND " GROUND . THIS CAUSES THE SEAT TO SLIDE FORWARD 100 MM
IN THE WALK±IN MODE. HOWEVER, WHEN THE INITIAL SLIDE POSITION IS 100 MM OR LESS FROM THE MOST FORE POSITION, THE
SEAT CAN ONLY SLIDE FORWARD AS FAR AS THE MOST FORE POSITION.
