How are Car Diagnostics Read?
Professional mechanics will measure the diagnostics of your car using a OBD-II code reader. This will tell them critical data about your car and repairs it may need. When something’s wrong with the car, the computer sends fault codes to its sensors. There are more than 3,000 generic and model-specific fault codes used, and each has a different meaning and function. You can look up each code online to find out more information. Some people purchase their own code readers to find out information on their own. You can also use apps that connect to your smartphone, though you may need to purchase additional equipment. Some automotive parts stores will test your car for free.
