45601900 Removing and Installing Steering-Angle Sensor

WM 456019 Removing and installing steering-angle sensor

General information

The steering-angle sensor is integrated into the => see figure steering column switch.





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-.










Replacing the steering-angle sensor









1. In order to replace the steering-angle sensor, the contact unit for airbag -C- and the electronic unit -E- must be replaced => 945019 Removing and installing steering column switch (Removing and installing steering column switch includes disassembly and assembly).
2. Once installed, the steering-angle sensor must be calibrated for the PSM system using the Porsche System Tester => 456015 Initialising and calibrating steering-angle sensor.
