Since the mid-1990s, cars have featured widespread digital components that control sensors, combustion, and electrical interactions. These features allow for computer diagnostics to be performed with specialized tools using software that scans for problems and reveals any occurring malfunctions. Here is a brief guide to these high-tech tests.

What Kinds of Issues Can Computer Diagnostics Identify?

Computer components are present in nearly every major system inside your vehicle, including the engine and its surrounding parts. You can also find them in the transmission, brakes, exhaust system, fuel injector, ignition coils, and throttle. A diagnostic test can reveal the area affecting the performance of your car, helping you catch problems before they become a more serious matter. For instance, it will let you know if the brakes need replacement.

While this examination can prevent accidents and expensive repairs, it can't specify the exact issue. Once the software identifies the problem area, a technician will examine the vehicle. At that point, the professional will combine information from the computer testing and visual inspection to present you with the options available for necessary fixes.

How Often Should a Test Be Performed?

Most drivers wait to take their car in for testing until they notice a significant performance issue. They may even have the check engine light turned on for weeks before finally taking the car into an auto shop. 

Instead of waiting for problems to arise, take the vehicle to an auto shop as part of your preventative maintenance routine. Having it tested annually will address minor malfunctions before they become more serious in the future. The automobile will also need a checkup if you feel it vibrating, have difficulty steering, or hear odd noises, like knocking, squeaking, or grinding.
