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 ABS module detects the onset of wheel slip without the brakes being applied it signals the ECM, on the high speed CAN bus, to request a momentary increase in engine torque.
