Engine Drag Control (EDC) (Only Certain Versions)

Engine Drag Control (EDC) is a function that is part of the DSTC function. It is a stability function that prevents the wheels locking when engine braking. These situations can occur on slippery surfaces when the driver quickly releases the accelerator pedal or when down shifting. To prevent the wheels from locking, the Brake control module (BCM) requests an increase in wheel torque from the Engine control module (ECM). EDC can also prevent the wheels locking when braking with ABS on slippery surfaces.
