Electronic Power Control (EPC) Warning Lamp Activation In Instrument Cluster







EPC warning lamp in instrument cluster

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

The 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 ECM does not detect a malfunction in the EPC system and, secondly, that activation of the lamp by the ECM is OK.

If malfunctions are recognized in the EPC system during operation of the engine, the ECM switches on the EPC warning lamp in the instrument cluster. (These malfunctions are listed in the DTC table). An entry is made in DTC memory at the same time.
