Not sure what this refers to? Where do you find this application, and in what system?

The EPC light indicates that there is an issue with the Electronic Power Control (EPC) System. The issue is often related to your throttle control system, but it may also be a problem related to your traction or cruise control system.
The Electronic Power Control system is controlled by the engine control unit, brake control unit, transmission control unit and the steering control unit.

The EPC light is often showing up with other warning lights and because it's integrated with a lot of different systems, it's hard to just guess where the problem is located.

The EPC Light does also often cause your car to go into "Limp mode". Limp mode will restrict the functions in your engine control unit, such as limited RPM, low power, etc.
