Why do steering angle sensors require calibration?
For stability control and steering sensors to be accurate, most of them need to be calibrated on the vehicle, either with a scan tool, specific procedures or a short period of driving.
How do you initialize the steering angle sensor?
- Inspect the wheel alignment, inflation pressure, and the installation condition of the steering wheel.
- Connect the negative battery cable.
- Turn the ignition switch to the ON position.
- Confirm that the DSC indicator light illuminates and that the DSC OFF light flashes.

How do I know if my BMW steering is active?
Is Active Steering the same as power steering?
“Active Steering.” Unlike regular power steering, which has either a fixed or narrowly variable steering ratio, or full steer-by-wire, where the only connection between the steering wheel and the road wheels are electrical wires, Active Steering connects the steering wheel and road wheels through a planetary gearbox.
Where is the steering wheel sensor located?
Steering Angle Sensor. The steering angle sensor measures the steering wheel position angle and rate of turn. It is placed in the steering column of the vehicle. More than one angle sensor can be used to provide redundancy and data validation.
What is active steering on BMW?
The BMW active steering system utilizes a double planetary gear system located at the base of the steering column to facilitate driver independent steering of the front wheels. The system is intended to offer two principal benefits; a variable steering ratio and stability-enhancing corrective steering actions.
