Electronic Power Control (EPC) Warning Lamp -K132- In Instrument Cluster

"EPC" is an abbreviation and stands for Electronic Power Control.

Engine Control Module (ECM) checks all components that are important for function of the EPC system after ignition is switched on.

If malfunctions are recognized in the EPC 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.
