The ABS control module counts 29 pulses per wheel revolution. Depending on the size of tire and wheel (physical circumference), one kilometre will
correspond to a different number of pulses when the main instrument unit obtains a reading from the ABS. It is therefore possible to change the main
instrument unit's interpretation of the total number of pulses per kilometre so that it corresponds to the size of tire fitted on the car.
The tire size is programmed with Tech 2
