What is car diagnostic?

Auto Tech Tools
Car diagnostic tools are devices or software programs that are used to identify and troubleshoot problems with a car's engine, transmission, and other systems. These tools are often used by mechanics and other automotive professionals to diagnose problems with a vehicle, but they can also be used by individuals to diagnose problems with their own cars.
There are many different types of car diagnostic tools available, and the specific tool used will depend on the make and model of the car being tested as well as the type of problem being diagnosed. Some common types of car diagnostic tools include:
OBD (On-Board Diagnostics) scanners: These are handheld devices that can be plugged into a car's OBD port to access the car's diagnostic system. OBD scanners can display error codes, monitor system performance, and perform tests to help identify problems with a car's engine, transmission, and other systems.
PC-based diagnostic tools: These are software programs that are installed on a computer and used to diagnose problems with a car's engine, transmission, and other systems.
Specialized diagnostic tools: Some car diagnostic tools are designed to diagnose specific types of problems, such as electrical issues or problems with a car's transmission.
Car diagnostic tools often include repair or troubleshooting guides to help users fix identified problems. They may also include diagnostic routines and other features to help users diagnose and fix problems with their cars.
