THIRD ROW POWER FOLDING SEATSystem Description
The third row power folding seat system is capable of allowing a user to fold up or down either the left or right third row seat using a set of front or rear mounted switches.
THIRD ROW POWER FOLDING SEAT CONTROL UNIT
The third row power folding seat control unit is located in the control unit/cross beam assembly underneath the LH third row seat. It receives signals from the third row power folding seat switches, TCM and the Hall effect switches mounted in the LH and RH seat motors. The control unit has self-diagnosis capability through chime codes and may be accessed by turning the ignition switch ON and OFF three times. The control unit drives the LH and RH seat motors to fold them up and down.
THIRD ROW POWER FOLDING SEAT SWITCH
The third row power folding seat switches are located in pairs on the luggage side finisher RH. A switch must be held in order for the seat to move.
THIRD ROW POWER FOLDING SEAT MOTORS
The third row power folding seat motors are located in the seat motor/hinge assembly. There are two motors, one for LH and one for RH seat folding operations. Power and ground are provided to the motors by the third row power folding seat control unit. The control unit reverses polarity to the motors to raise or lower the seat. The motors also contain Hall effect switches. These switches send signals back to the control unit which help it determine fully open and closed positions.
