Electronic Engine Power Control (EPC), Significance

Electronic Power Control (EPC) Warning Lamp In Instrument Cluster


NOTE: The Electronic Power Control (EPC) warning lamp -k132- is also called the fault light for power accelerator activation.


"EPC" is an abbreviation and stands for Electronic Power Control (E-gas).

Installation location of EPC warning lamp







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

The Engine Control Module (ECM) switches on the EPC warning lamp after ignition is switched on. Shortly after engine is started, the EPC warning lamp will go out. This requires, first of all, that the Engine Control Module (ECM) does not detect a malfunction in the E-gas system and, secondly, that activation of the lamp by the Engine Control Module (ECM) is OK.

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.
