Seats: Description and Operation
1. MANUAL SLIDE OPERATIONWhen the slide SW of the power seat control SW is pressed to FRONT position, the signal is input to TERMINAL B 15 of the power seat ECU. This activates the power seat ECU to flow the current into TERMINAL A 3 of the power seat ECU to TERMINAL 2 of the power seat motor (Slide control) to TERMINAL 1 to TERMINAL A 4 of the ECU to GROUND, to move the seat forward while the power seat control SW is kept pressed.
When the slide SW of the power seat control SW is pressed to the REAR position, the signal is input to TERMINAL B 16 of the power seat ECU. This activates the ECU to flow the current into TERMINAL A 4 of the power seat ECU, TERMINAL 1 of the power seat motor (Slide control) to TERMINAL 2 to TERMINAL A 3 of the ECU to GROUND to move the seat back backward.
At this time, the power seat position sensor (Slide control) detects the seat position and always inputs it to TERMINAL B 14 of the power seat ECU.
2. MANUAL RECLINING CONTROL
When the reclining SW of the power seat control SW is pressed forward, the signal is input to TERMINAL B 21 of the power seat ECU. This activates the power seat ECU to flow the current into TERMINAL A 1 of the power seat ECU to TERMINAL 1 of the power seat motor (Reclining control) to TERMINAL 2 to TERMINAL A 2 of the ECU to GROUND, to tilt the seat back forward while the power seat control SW is kept pressed.
When the reclining SW of the power seat control SW is pressed backward, the signal is input to TERMINAL B 22 of the power seat ECU. This activates the ECU to flow the current into TERMINAL A 2 of the power seat ECU, TERMINAL 2 of the power seat motor (Reclining control) to TERMINAL 1 to TERMINAL A 1 of the ECU to GROUND, to tilt the seat backward.
At this time, the power seat position sensor (Reclining control) detects the seat back position and always inputs it to TERMINAL B 5 of the power seat ECU.
3. MANUAL FRONT VERTICAL CONTROL
When the front part of the slide SW of the power seat control SW is pushed up, the signal is input to TERMINAL B 19 of the power seat ECU. This activates the power seat ECU to flow the current into TERMINAL A 10 of the power seat ECU to TERMINAL 1 of the power seat motor (Front vertical control) to TERMINAL 2 to TERMINAL A 9 of the ECU to GROUND, to raise the front part of the seat cushion while the power seat control SW is kept pressed.
When the front part of the slide SW of the power seat control SW is pushed down, the signal is input to TERMINAL B 7 of the power seat ECU. This activates the power seat ECU to flow the current into TERMINAL A 9 of the power seat ECU TERMINAL 2 of the power seat motor (Front vertical control) to TERMINAL 1 to TERMINAL A 10 of the ECU to GROUND, to lower the front part of the seat cushion while the power seat control SW is kept pressed.
At this time, the power seat position sensor (Front vertical control) detects the seat cushion position (Front) and always inputs the signal to TERMINAL B 3 of the power seat ECU.
4. MANUAL REAR VERTICAL OPERATION
When the rear part of the slide SW of the power seat control SW is pushed up, the signal is input to TERMINAL B 17 of the power seat ECU. This activates the power seat ECU to flow the current into TERMINAL A 6 of the power seat ECU to TERMINAL 2 of the power seat motor (Rear vertical control) to TERMINAL 1 to TERMINAL A 5 of the ECU to GROUND, to raise the seat while the power seat control SW is kept pressed.
When the rear part of the slide SW of the power seat control SW is pushed down, the signal is input to TERMINAL B 18 of the power seat ECU. This activates the ECU to flow the current into TERMINAL A 5 of the power seat ECU to TERMINAL 1 of the power seat motor (Rear vertical control) to TERMINAL 2 to TERMINAL A 6 of the ECU to GROUND, to lower the seat while the power seat control SW is kept pressed.
At this time, the power seat position sensor (Rear vertical control) detects the seat cushion position (Rear) and always inputs the signal to TERMINAL B 4 of the power seat ECU.
5. MANUAL LUMBAR SUPPORT OPERATION
When the lumbar support control SW is pressed forward, the current flows from the D P/SEAT fuse into TERMINAL 4 to TERMINAL 1 of the lumbar support control SW to TERMINAL 2 of the power seat motor (Lumbar support control) to TERMINAL 1 to TERMINAL 2 of the SW to TERMINAL 3 to GROUND, to move the lumbar support forward.
When the SW is pressed backward, the current from the D P/SEAT fuse flows into TERMINAL 4 to TERMINAL 2 of the lumbar support control SW to TERMINAL 1 of the power seat motor (Lumbar support control) to TERMINAL 2 to TERMINAL 1 of the SW to TERMINAL 3 to GROUND, to move the lumbar support backward
6. DRIVING POSITION MEMORY FUNCTION
Each position sensor in the seat detects the number of rotations of the relevant motor (Seat movement amount) and inputs it to the ECU. This makes it possible to store and recall the seat position by operating the position memory SW. The driving seat position is stored and recalled through communication control of the body ECU and door ECU etc.
