Steering Angle Sensor: Service and Repair
Removing and installing steering angle sensorGeneral information
The steering angle sensor is integrated into the -steering column switch-.
The steering angle is recorded in the contact unit for airbags (spiral spring) -C-. The data determined is sent from the electronic unit -E- via the drive CAN bus to various systems (e.g., PSM, corner-sensitive headlight) for further processing. The steering column switch must be removed in order to replace the steering angle sensor.
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-.
^ It is only permissible to replace the steering angle sensor in combination of components, contact unit for airbag -C- (spiral spring) and electronic unit -E-.
