After initiation, with the ignition key in position II and when the steering wheel is turned 4.5 degrees in any direction, the control module for the steering wheel angle sensor continuously transmits information about the steering wheel angle position to the brake control unit to calculate the driving style of the driver. The brake control module was called ABS-control module up to and including model year 2001.

Communication between the Steering wheel angle sensor control module and the brake control module occurs on the high speed side of the Controller area network (CAN). The control module for the steering wheel angle sensor is positioned on a bracket inside the central electronic module.

The control module for the steering wheel angle sensor is supplied with power from the overload relay.
