Car diagnostic tests examine a variety of aspects of your vehicle. They can scan your vehicle’s mechanisms and systems for problems with components such as the engine, transmission, oil tank, throttle, and many others. They specifically look for the following things:
Engine or individual component failures in your vehicle
Transmission and responsiveness issues with your vehicle
Brake responsiveness issues
Contamination or flaws in your vehicle’s exhaust system
Wear and tear or component failure with major components of your vehicle such as the fuel injector, ignition coils, and throttle
The results that a mechanic receives from a vehicle diagnostic test can narrow down the location of an issue or potential error so that they can identify and correct your vehicle’s problem quickly.
You should get a vehicle diagnostic test when you have a warning light lit on your vehicle’s dashboard.
