MEMORY SEAT CALIBRATION PROCEDURE

The memory seat module uses position sensor inputs to establish soft stop locations for the adjuster motors
several millimeters ahead of the physical limits of the adjuster assembly. After replacing a memory seat module
or adjuster components, it may be necessary to reset the adjuster motor soft stop locations. When the repair
procedure has been completed, operate the seat adjuster switch in every direction until the seat adjuster reaches
its mechanical hard stop by repeatedly pressing and releasing the switch as necessary.
