The steering wheel angle sensor (7/91) is integrated in the Steering wheel module (SWM) (3/254) and registers information about the steering wheel's angle and the number of steering wheel turns that have been made. The Steering wheel module (SWM) then transmits the information via the CAN network to the Brake control module (BCM) (4/16) (only vehicles with DSTC) and the Electrical power steering module (EPS) (4/99).
