Professional equipment is needed to read the stored trouble codes, which can save time in diagnosing the issue. Only after understanding the trouble codes and data streams can you analyze the components that may be faulty. 2. During the use of the car: Regular maintenance is essential. Check if the fuel filter is aging and replace it promptly if necessary. During maintenance, the car's power system should also be inspected to promptly identify any potential safety hazards.
