Steering Angle Sensor Module (SASM)
WARNING: This page is about a different car, the 2015 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The SASM transmits steering wheel position, direction and speed of rotation information on the HS-CAN. The module is self monitoring and capable of setting Diagnostic Trouble Codes (DTCs). The SASM is also self calibrating and learns the straight-ahead position of the vehicle as it is driven. When a new SASM is installed, the vehicle configuration information is automatically transmitted from the BCM when the ignition is set to ON.
