What does the EDC fault light mean?

[DelXavier]

EDC fault light indicates that there is a problem with the vehicle's high-pressure electronic injection and electronic control system, which means there is an issue with the engine. It is necessary to go to a 4S shop and have professional maintenance personnel inspect and repair it. Car owners should not attempt to inspect it themselves to avoid causing damage to the engine. The EDC light being on means there is a fault in the engine, and specialized computer diagnostics are required for inspection and analysis. Be careful not to loosen any parts for inspection on your own. When the EDC fault light comes on, if the engine can start and operate normally, the problem is not serious. It may be due to damage to the engine's high-voltage circuit, fuel injector, or oxygen sensor, leading to increased fuel consumption. If the engine cannot start normally, it is necessary to go to a 4S shop to check whether there are faults in the high-voltage wires, spark plugs, etc.
