What are the effects when the EDC warning light comes on in a diesel vehicle?

When the EDC warning light comes on in a diesel vehicle, it indicates a fault in the engine's electronic control system. Here are the specific details: 1. Concept explanation: The appearance of EDC (Electric-Diesel-Control) on the car dashboard refers to electronic control of diesel injection, which typically indicates an engine fault. If the vehicle can still start, there may not be a major issue. 2. Troubleshooting: The illuminated engine warning light does not cause significant harm to the engine but may lead to increased fuel consumption. The problem is usually related to the engine's high-voltage circuit, fuel injector components, or oxygen sensor circuit. First, check if the high-voltage wires or spark plugs have been affected by water from washing or rain, or if they have become loose. The EDC letters indicate an engine circuit fault, which is often caused by starter maintenance issues.
I remember when the EDC warning light came on in my diesel car, the vehicle immediately lost power, accelerating very slowly and struggling even on inclines. Fuel consumption skyrocketed, dropping from my usual 500 km per tank to less than 400 km before running empty. The mechanic explained that the light indicates an issue with the electronic control system, possibly due to clogged fuel injectors or faulty sensors. Continuing to drive would pollute the environment with excessive emissions and accelerate engine wear. Repairs can be costly—I once spent thousands replacing fuel injectors. There are safety concerns too; stalling on the highway could be dangerous. It's advised to pull over immediately for inspection rather than risking further damage by pushing on.
