System Operation: EDC
EDC prevents wheel slip caused by any of the following:
- A sudden decrease in engine torque when the accelerator is suddenly released.
- The sudden engagement of the clutch after a downshift on manual transmission vehicles.
- A downshift using the CommandShift™ on automatic transmission vehicles.
When the anti-lock brake system (ABS) module detects the onset of wheel slip without the brakes being applied it signals the engine control module (ECM), on the high speed controller area network (CAN) bus, to request a momentary increase in engine torque.
