CAN ERROR – Engine speed (RPM)

Fault Code Table : ABS 1

The first BMW ABS system, This was a 3 channel system, controlling braking to the front wheels,and a single line for both rear wheels. The wheel speed info could be passed via data lines to traction control systems, which could determine if the vehicle speed signal given from the rear driven axle did not match with the front wheel speed signals and request torque reduction intervention from the ASC (Anti Skid Control) throttle body.

Motor Temperature over CAN bus

Fault Code Table : ABS 2

The updated version of BMW’s ABS system, this was more advanced. Improvements include a 4 channel system for independent rear wheel braking, which allowed a more active ASC system. With individual braking, not only could a torque reduction be requested via the ASC secondary throttle body, but independent wheel braking could be used to control individual wheel slip as part of a stability program.
