The illumination of the power system warning light is naturally caused by issues within the power system, such as faults in individual battery cells within the battery pack, motor controller malfunctions, or motor failures. To further pinpoint the fault, it is necessary to use a diagnostic tool specifically designed for the electric vehicle model in question. By identifying the module reporting the fault and reading the data stream, the root cause can be determined and addressed. Solution: When the EDC warning light comes on, it is advised that vehicle owners refrain from attempting to dismantle or inspect components on their own. Unprofessional handling can easily lead to high-pressure fuel line leaks, resulting in more severe subsequent issues. Therefore, it is recommended that owners seek immediate assistance from a professional auto repair shop when such problems arise, allowing experts to conduct a thorough inspection and analysis using specialized diagnostic equipment. EDC Warning Light: The EDC warning light stands for Electric-Diesel-Control, which refers to electronic control of diesel injection. Once this light illuminates, it is advisable for the vehicle owner to promptly drive the vehicle to the nearest auto repair shop for a comprehensive inspection and repair.
