How to Resolve EDC Malfunction?

[Justin]

EDC warning light illumination indicates a fault in the engine electronic control system. If the vehicle fails to start, it is recommended to have it inspected at a 4S shop. The EDC acronym refers to an engine circuit malfunction. This is typically caused by starter motor repairs, as the starter incorporates a loopback system. Many technicians replace it with older starter switches lacking this system, triggering a computer-detected fault (though operational performance remains unaffected). Reference materials: 1. Antifreeze Usage Tips: Antifreeze should ideally be used year-round. Beyond freeze protection and cooling, it also provides cleaning, rust removal, and anti-corrosion benefits, reducing radiator corrosion and protecting the engine. Always select the correct antifreeze color and avoid mixing different types. 2. Brake Fluid Knowledge: Brake system performance is closely tied to brake fluid condition. When inspecting/replacing brake pads or discs, always check whether brake fluid requires replenishment or replacement.
