INFOID:0000000005518141
System Description

DESCRIPTION
• The rear seat back power return system is the system that enables the return operation of the left and right
rear seatbacks independently by pressing and holding the power return switch on the instrument panel or in
the luggage room.
• As for the safety mechanism, the reverse operation is performed if the power return switch is released during
the return operation. The anti-pitch function is installed so that the automatic reverse operation is performed
if the pinching of foreign materials between the left and right rear seatbacks is detected.
OPERATION DESCRIPTION
The rear seatback power return system consists of the sector gear that transmits the movement information of
rear seatback power return control unit, power return switch, power return motor, motor sensor, primary posi-
tion limit switch, return complete limit switch and power return motor.
Return Operation Starting Condition
The rear seat back return operation starts when all of the following conditions are satisfied.
• Vehicle speed 2 km/h (1 MPH) or less
• Return complete limit switch: ON
• The battery voltage is normal
• In the condition that the rear seatback is raised (return completion position), the sector gear is in the initial
position and the primary position limit switch and return complete limit switch are OFF.
• When manually operating the rear seatback to the fold-down position, the return complete limit switch turns
ON, and the rear seatback power return control unit judges that the rear seatback is tilted (return non-com-
pletion position).
