What does it mean when brake light and battery light came on? The 'E' brake (parking brake) light comes on when the fluid is low in the master cylinder or there is a pressure difference in the brake system. Have the alternator checked and see if the battery cables are tight. The battery light indicates a battery charging problem. What does EPC battery mean? Electronic Power Control EPC just means "Electronic Power Control," could be like....anything. Step one is replace the battery, since it's bad anyway. Have AutoZone read the code when you pick the battery up and make sure...
