Steering Angle Sensor Module (SASM)
WARNING: This page is about a different car, the 2016 Ford Transit-350 HD, 2016 Ford Transit-350, 2016 Ford Transit-250, and 2016 Ford Transit-150. However, it is still accessible from the selected car via links, so may be relevant.
The SASM transmits steering wheel angle 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.
