DSC 8 General Information
E60 DSC 8 General InformationCalibrating the steering-angle sensor
Calibration must be performed after the following operations:
- Replacement of steering column switch cluster (SZL)
- Programming of steering column switch cluster (SZL)
- Replacement of steering gear with cumulative steering-angle sensor (on vehicles with Active Front Steering)
- Work on the front-axle or steering
- Adjusting work on the steering geometry
During calibration, the steering-wheel position set is stored in the steering-angle sensor as the straight- ahead position. For this reason, the steering wheel must be precisely in the straight-ahead position when the front wheels are calibrated. Calibration must be performed with the BMW diagnosis system.
Note: Note different vehicle identification numbers
It is not possible to calibrate the steering-angle sensor if the vehicle identification number stored in the steering column switch cluster differs from that stored in the instrument cluster.
Important! When replacing the DSC control unit
When replacing the DSC control unit, the Repair Instructions must be observed (special tools needed).
Vehicles with Active Front Steering have a different DSC control unit than vehicles without
Active Front Steering
Note: Steering angle on vehicles with Active Front Steering
On vehicles with Active Front Steering, DSC regulation requires the cumulative steering angle (= steering angle at steering wheel plus steering angle at Active Front Steering variable-ratio steering gear).
The signal from the cumulative steering-angle sensor (on the steering gear) is output as a message directly in the chassis CAN. This ensures that DSC remains functional even if the Active Front Steering should fail.
E60 - DSC 8, Encodinglprogramming Encoding the steering-angle sensor
Important! The steering-angle sensor must not be encoded!
Encoding is not necessary, as on the E65. The steering-angle sensor is a component of the steering column switch cluster that is unambiguously assigned to the vehicle model.
Automatic Encoding Of The DSC Control Unit
After replacing the DSC control unit, the DSC control unit is automatically encoded. If the vehicle identification number differs, the DSC control unit will obtain the necessary data (vehicle identification) from the vehicle order. The vehicle order is stored in the instrument cluster.
