What does epc mean in Jianghuai Kang Ling?

Electronic throttle failure. The EPC light will be on all the time to remind the owner that something is out of order and must be repaired, but in fact the car is all right and no problems are found. This may be because the quality of domestic oil products is difficult to meet the stricter exhaust emission standards in Europe, and the computer keeps calling the police for this. You can clean the throttle and make a match.
