Circuit/System Description
WARNING: This page is about a different car, the 2010 GMC Canyon and 2010 Chevrolet Colorado. However, it is still accessible from the selected car via links, so may be relevant.
The electronic brake control module (EBCM) receives a digital and an analog steering wheel position signal from one sensor. The EBCM uses the steering wheel position sensor signals to perform Vehicle Stability Enhancement System (VSES). The digital data parameter will calibrate to 0° after each key cycle regardless of actual steering wheel position. The EBCM verifies the accuracy of the steering wheel position signal by correlating the digital and analog signals together.
