Vehicle diagnostics is the process of identifying and resolving problems with a vehicle's engine, transmission, and other systems. It can be done manually or with the help of a diagnostic tool. Manual diagnostics involves checking the vehicle's fluids, belts, hoses, and other components for signs of wear or damage. It also includes checking the vehicle's error codes, which can provide clues about the source of a problem.

Diagnostic tools can be used to read the vehicle's computer and retrieve information about its performance. This information can be used to identify problems that might not be apparent during a manual inspection.

Vehicle diagnostics is an important part of preventive maintenance. By identifying and resolving problems early, you can help to prevent costly repairs down the road.

If you are experiencing any problems with your vehicle, it is important to have it diagnosed by a qualified technician. Early diagnosis and repair can save you time, money, and hassle.
