Steering Wheel Angle Sensor Module (SAS)
After initiation, with the ignition key in position II and when the steering wheel is turned 4.5 degrees in any direction, the steering wheel angle sensor module (SAS) continuously transmits information about the steering wheel angle position to the brake control module (BCM) to calculate the intended direction of travel. The steering wheel angle sensor module (SAS) also transmits information to the suspension module (SUM).
Communication between the steering wheel angle sensor module (SAS) and the brake control module (BCM) occurs on the high speed side of the controller area network (CAN). The steering wheel angle sensor module (SAS) is integrated in the steering wheel module (SWM).
The steering wheel angle sensor module (SAS) is powered via the steering wheel module (SWM).
