Steering Wheel Angle Sensor
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2013 Volvo C70, 2012 Volvo C70, 2011 Volvo C70, 2010 Volvo C70, and 2009 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.
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).
