Total Steering-Angle Sensor And Steering Angle Sensor

The total steering angle sensor captures the steering angle that the Active Front Steering produces at the steering box (total steering angle- angle at steering pinion). As far as its function is concerned, the total steering angle sensor corresponds to the steering angle sensor in a conventional steering system.

The steering angle sensor in the steering column switch cluster (SZL) captures the angle to which the driver turns the steering wheel. Both signals are needed by the AFS control module.

• The steering angle sensor is an optical sensor on the E90.

Both sensors are connected to the F-CAN in order to transmit data to the AFS and DSC modules.
