Power Seat (Rear Passenger's Seat)

SYSTEM OUTLINE

1. MANUAL OPERATION
If the rear seat control SW is operated, the signal is sent to the rear seat ECU by the multiplex communication. As a result of that, the rear seat ECU controls the motor to operate and the rear seat slides or the headrest moves up or down, or back and forth so that the passenger adjust the position of the rear seat of headrest at will.

2. REAR SEAT RETURNING OPERATION
If the any of the rear doors is opened, the rear seat position is returned automatically to the original position before the sliding controlled by the rear seat ECU.

3. MEMORY AND REGENERATION OPERATION
The rear seat ECU detects the positions of the rear seat and the headrest by each position sensor. And by operating the rear seat memory SW, the positions of the power seat and the headrest can be memorized and regenerated.

4. DOOR OPEN INTERLOCK RETURN OPERATION
Using the multiplex communication, the rear seat ECU detects the rear door opening under the following conditions:
- During rear doors are closed with the ignition SW being ON
- Not during the manual operation and the buckle SW interlock operation
- Not during the rear seat returning operation and when the door open interlock return operation is not canceled.
- When the brake pedal is depressed while the vehicle speed becomes 5 km/h or less
- When the shift position is P

As a result of that, the rear seat ECU controls the motor to operate to move the rear seat position backward. However, the operation will stop under the following conditions:
- When the ignition SW is turned to OFF
- When the manual operation is performed
- When the rear seat returning operation is performed
- After about 30 seconds from the operation stops
- When the motor lock is detected
- When SET or C SW is turned to ON
- When the buckle SW interlock operations is performed
Moreover, operating the C SW while the ignition SW is ON can set the door open interlock operation in active or not.

However, it can not be set under the following conditions:
- During the manual operation
- During the memory regeneration operation
- During the door open interlock return operation
- During the rear seat returning operation
- During the buckle SW interlock operation
