Function
If the motor moves against the mechanical end stop, motor
lock-up is recognized by the position measurement feature.
The driver-side ESA control module (N32/1) or passenger-side ESA control module (N32/2) stores the position measurement counter position. The next time the seat is moved in the direction of
this end stop, the motor is slowed down just before reaching
the stored position. This prevents the seat from hitting hard against the end stop.
-----------------------------------------------------------------------------------------
The stored position is erased when
the adjustment mechanism in question has been actuated 250 times or
the control module was disconnected from the power supply or
the remaining travel between the stored positions for an adjustment direction is less than 90 % of the total possible adjustment travel in that direction.
