Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Steering Angle Sensor Module (SASM)
The SASM transmits steering wheel position, direction and speed of rotation information on the High Speed Controller Area Network (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. However, when a new SASM is installed, the module must be programmed with the correct vehicle information.
