Electronic Power Control Warning Lamp

The ECM monitors electronic power control (EPC) components when the ignition is switched on.

If a malfunction is recognized in the EPC system, the ECM switches on the EPC warning lamp in the instrument cluster, and an entry is stored in the DTC memory of the ECM.
