What is Car Diagnostic Scanning?
Car diagnostic scanning is a process of connecting your vehicle to specialized diagnostic equipment that communicates with the car’s onboard computer system. This system stores fault codes whenever it detects abnormal behavior in engine, transmission, brakes, or other components.
These codes help technicians:
- Identify hidden issues
- Understand system failures
- Monitor vehicle performance
- Prevent major breakdowns
Diagnostic scanning is the first step toward accurate repair and long-term vehicle reliability.
