Steering wheel angle sensor module (SAS) is located inside, and is supplied with power by, the steering wheel module (SWM). Only the steering wheel angle sensor module (SAS) communicates on the controller area network (CAN).

The Steering wheel angle sensor module (SAS) contains 2 x processors that operate together. The processors receive information about steering wheel angle, steering direction and steering angle speed from the steering wheel angle sensor module (SAS) and compare the information with each other. The diagnostic trouble code (DTC) is stored if the steering wheel angle sensor module (SAS) registers that the information is incorrect in any way.

The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on and the steering wheel angle sensor is initiated. Initiation is carried out when the steering wheel is turned more than 4.5° in any direction.
