Function 

There is one Hall sensor per adjusting motor for measuring the seat position at the left (M27) or right (M28) front seat adjustment motor groups with memory.

The Hall sensor signals are read in by the driver-side front seat adjustment control unit with memory (N32/1), a plausibility check is performed, and the signals are counted in the location counter in order to measure the location. The received Hall pulses are either evaluated as positive or negative, depending on the actuation voltage of the motor.
