"EPC" is an abbreviation and stands for Electronic Power Control (E-gas).
Engine Control Module (ECM) checks all components that are important for function of the E-Gas system after ignition is switched on.
If malfunctions are recognized in the E-Gas system during operation of the engine, the ECM switches on the EPC warning lamp in instrument cluster. (These malfunctions are listed in the DTC table). An entry is made in DTC memory at the same time.
