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.
Engine Drag Control (EDC) (Only Certain Versions)
Engine Drag Control (EDC) is a function that is part of the DSTC/ESC 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.
For a further information about the function, see appropriate Design and Function information for the Brake control module (BCM).
