(special equipment, model 220 only)

The adjustment motors for the left rear seat adjustment motor group (M18/1)/right (M18/2) have one Hall sensor each for position measurement.

Position measurement

The signals from these Hall sensors are read in by the left front seat adjustment control module with memory (N32/1)/right front seat adjustment control module with memory (N32/2) and rear seats control module (N25/6, model 220 only), checked for plausibility and counted in the internal position counter. The received Hall pulses are evaluated as positive or negative according to the actuation voltage of the motor. A faultless position measurement is only possible in the normalized condition. It is a prerequisite for the ergonomics default setting function.
