Common Questions About Car Diagnostic Testing

What is car diagnostic testing? Since the computerization of auto components, software became the primary tool in auto shops in Chino, CA and across the nation, highlighting the importance of the car diagnostic test. Car diagnostic testing involves plugging a computer into your car’s central computer so that the software can find mechanical, electrical and other repair issues with your vehicle. It streamlines repair appointments and enhances accuracy. Here are some of the most common questions about this method.

What do you test?

Diagnostic testing checks the engine, transmission, exhaust system, brakes and other significant functions in your vehicle. It proves essential with performance issues involving fuel injectors, ignition coils, throttles and the airflow and coolant systems.

Mechanics frequently use the test when the check engine light illuminates. The computer reads codes created by your car’s internal computer, and those codes indicate which systems are out of their range. From there, your mechanic has a better understanding of where to look deeper to repair your car.

This process sounds like it will cost more! Are there any benefits?

Diagnostic testing actually reduces repair expenses. Before computerization, finding issues with cars was time-consuming. Car owners explained weird noises and handling problems, and mechanics tried to recreate the issue and detect it. This process often increased labor costs.

Also, cars often did not make it to the shop until a catastrophic breakdown or malfunction. By that time, labor and parts prices both increased. Now, with diagnostic testing, you learn if your transmission is acting up or if your exhaust system is close to failure. That allows you to address these issues before they blow up. Since many system failures take other components with them, you also reduce the risk of compromising your entire vehicle.

How frequently should I order car diagnostic testing?

Most shops perform the test at every maintenance and repair appointment. There is no set schedule or recommended frequency. Make use of this tool whenever your car gives you trouble.

I found a used car I like. Will diagnostic testing reveal hidden problems?

Yes! Consider taking all possible car purchases to your mechanic for diagnosis. If a seller does not agree to this step, assume there is something wrong, and walk away. But if you agree to this step before finalizing a sale, you can rest assured you will get a great deal rather than someone else’s problem!

Where can I schedule diagnostic testing?

Any mechanic’s shop with updated equipment offers the ability to perform this test. Call ahead and set up a maintenance, repair or inspection appointment. Depending on the shop, you may pay a diagnostic fee, but it will cost much less than unexpected repairs!
