How to reset the EPC warning light by yourself?
1 Answers
The methods to reset the EPC warning light by yourself are: 1. Troubleshoot the intake system, use qualified fuel, and clean the throttle body; 2. Remove carbon deposits from related parts; 3. Rewrite EPC-related data; 4. There may be other faults causing the issue, so it's best to check the fault codes for accurate diagnosis. The EPC light indicates a fault in the engine management system or electronic control, often accompanied by unstable idling or engine cold start shaking. It could also be due to a dirty throttle or malfunctioning brake lights. After turning the ignition key, the vehicle performs a self-check, and the EPC light will illuminate for a few seconds before turning off. If it remains on after starting the vehicle, it indicates a mechanical or electronic system fault.
