System Parameterization

Due to mechanical tolerances and adjustments in vehicle production and assembly the power operated liftgate needs calibration of the maximum movement range before proper operation can be ensured.

The liftgate's maximum movement range is represented by the number of Hall-pulses received by the ECU from the actuators' speed/position sensors during a liftgate movement from the fully closed position (closure unit in fully latched position) to the upper end position limited by mechanical constraints (e.g. upper bump stops, spindle length or similar).
