Engine Drag Control (EDC) (Only Certain Versions)

Engine Drag Control (EDC) is a function that is part of the DSTC function. The function ensures that the vehicle speed is not greater than the speed of the driven wheels. i.e. if the vehicle loses traction on the surface. The Engine control module (ECM) can increase the wheel torque on request so that the vehicle regains traction.
