The Role of Diagnostic Testing in Chevy Maintenance

Diagnostic testing is when a technician uses software to diagnose problems with your Chevy. This tool will save you time and money when visiting the professionals at your local Chevy dealer. Learn how we use this program to help you get back on the road as soon as possible.

Your Chevy Dealer: How Does Diagnostic Testing Help with Maintenance? 

Various sensors in the truck record the engine temperature, fuel and oil pressure, injection timing, and other important variables that can affect performance. All the data about your vehicle’s performance, including the condition of various parts and systems, is stored on the car’s internal computer. The testing unit collects the data to create a concise report of what issues need to be addressed.

Keep this information in mind when bringing your Chevy to our body shop:

How Does a Diagnostic Test Work?

One of our technicians will connect the testing tool to your car’s internal computer to quickly assess the problem. The testing device will produce an error code corresponding to a specific issue so the technician knows what needs to be fixed. The testing tool will also list any service notifications from the manufacturer.

The test analyzes all the car’s major components and systems, including the fuel injectors, oil pump, ignition coils, exhaust, coolant system, transmission, brakes, and turbocharger.

When to Get a Diagnostic Test

Bring your Chevy in for an inspection if you notice any of the following:

  • Strange sounds
  • Reduce power and acceleration
  • Dropping fuel efficiency
  • Check engine light comes on
  • Faster oil and coolant consumption
  • Wet spots under your vehicle
  • Excess smoke from the exhaust or hood
  • Strong odors

You should also bring your Chevy in for a routine inspection every 12 months, even if nothing is wrong with the car. The diagnostic tool will point out potential problems before extensive repairs are needed.

How Long Does It Take to Run a Diagnostic Test?

Running the test only takes a few minutes. One of our technicians will explain the problem, what needs to be fixed, and the estimated cost so you can make an informed decision.

Your Chevy needs regular maintenance to do its job. Having a trained technician perform a diagnostics test on your truck shows you how it’s performing under the hood so you can protect it from wear and tear.
