Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Electronic Power Control (EPC) Warning Lamp
EPC is an abbreviation that stands for the Electronic Power Control (E-gas).
The Engine Control Module (ECM) monitors all EPC components after the ignition is switched on.
If a malfunction is recognized in the EPC system during the operation of the engine, the Engine Control Module (ECM) switches on the Electronic Power Control (EPC) Warning Lamp which is located in the instrument cluster and an entry is stored in the DTC memory of the Engine Control Module (ECM).
