Assignment of wheels
NOTE:
A drive lasting for as long as 8 minutes may be required to allow the DSC to define the wheel assignments. The process for identifying the wheel assignments can be accelerated by driving on a stretch of road featuring a high number of curves.
During the wheel assignment identification process the wheel electronics are in the "learning" mode. Wheel rotation generates centrifugal force. The acceleration sensor starts to recognize this centrifugal force at a vehicle speed of approximately 30 km/h (18 mph). The acceleration sensor relies on the earth's gravitational force to identify the wheel electronics' vertical position (12 o'clock).
This position (12 o'clock) is needed for the "learning" mode.
In the "learning" mode the DSC identifies the positions of the four individual wheels with assistance from the wheel sensors.
