Circuit/System Description
WARNING: This page is about a different car, the 2007 Pontiac Solstice. However, it is still accessible from the selected car via links, so may be relevant.
When the electronic brake control module (EBCM) is replaced, software and calibrations are flash programmed into the EBCM. The EBCM receives the vehicle power-train options information from the power-train control module (PCM) in order for the EBCM to automatically calibrate to the vehicle.
