A diagnostic test is used to detect issues within the engine, exhaust or transmission as well as other major components. Performance issues can also be detected such as the throttle, injectors and ignition coils. The diagnostic equipment will tell the technician which component is not performing as should, the technician will then work to figure out the potential cause of this issue.
A diagnostic test can help to detect problems before it causes any serious damage or causes a breakdown. The cars computer will also store information about the history of the vehicle to help technicians carry out the best repairs for the vehicle.
