BMW Fault Code - 5D90

Fault Code Table : ABS 3

The ABS 3 system added yet more features to the previous systems, such as individual wheel speed comparison over long terms. Gathering the wheel rotation data, and comparing it is accurate enough to identify differences in tyre tread wear, but its main use was as part of a tyre pressure monitoring system. Decreases in the rolling circumference of the tyre from tyre deflation could be monitored as a passive system to identify low pressure in Run Flat Tyres which would often be hard to notice otherwise.
