The steering angle is recorded in the contact unit for airbags (spiral spring) -C-  . The sensed data is sent from the electronic unit -E-  via the drive CAN bus to various systems (e.g., PSM, corner-sensitive headlight) for further processing. Replacement of the steering-angle sensor requires the steering column switch to be removed.

If faults have been diagnosed on the steering-angle sensor, the steering column switch must be disassembled into the components -A, B, C, D, E-  .

The steering-angle sensor can only be replaced together with the contact unit for airbag -C-  (spiral spring) and the electronic unit -E-  .
