Electronic Power Control (EPC) Warning Lamp -K132- In Instrument Cluster
"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 Engine Control Module (ECM) switches on the Electronic Power Control (EPC) Warning Lamp - K132-. An entry is made in DTC memory of ECM at the same time.
