How to troubleshoot epc fault lights by yourself?

1. Troubleshoot the air intake system, select qualified fuel and clean the throttle body.

2. Remove carbon deposits on related parts and clean them. Rewrite the relevant data of ECU (which cannot be eliminated after solving other faults), and do not rule out the possibility caused by other faults. The actual vehicle test results shall prevail, and then the maintenance shall be carried out.

3. When the vehicle starts self-inspection, the EPC light will light up for a few seconds and then go out. If something is wrong, this light will come on. When the battery is low, the EPC fault light will light up. Under normal circumstances, it is recommended to go to the 4S shop for inspection and maintenance.
