Hello, EPC stands for Electronic Power Control. This typically has to do with throttle input to the engine. A warning light indicates some kind of issue that will require diagnostic testing to figure out. It's not even about "checking wiring" - it's about utilizing a diagnostic tool to figure out what's going on - and then checking the related circuit. More than could possibly be described in a forum like this.
