Pedal Position Sensor Potentiometer Supply Channel 1 (Pot 2 MS43)
The next generation Siemens MS ECUs introduced many of the OBD2 features. This includes Catalytic Converter monitoring and Long / Short term Fueling and Ignition Adaptation. The MS41 was used on the M52 series of engines, MS42 on the M52TU series, and MS43 on the M43 4 Cylinders.
The OBD2 P codes fault protocol was not activated in European markets on this group, as currently it was not required by law.

CAN ERROR – Engine Intervention
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.
