When the EDC warning light comes on, it essentially does not cause severe damage to the engine, but the most noticeable symptom is a significant increase in the vehicle's fuel consumption. At this point, it is recommended that owners refrain from arbitrarily disassembling components for inspection, as unprofessional operations may lead to high-pressure fuel pipe ejection, resulting in serious subsequent issues. Below are the common causes of EDC faults: 2. It is generally caused by starter motor repairs. Since the starter motor has a loop system, most repair technicians replace it with an older starter switch that lacks this loop system. Consequently, the computer detects a fault, though it does not affect usability. 3. Other causes include severe throttle carbon buildup, excessively high engine temperature, vehicle intake system malfunctions, and ECU faults.
