What Is the Purpose of Diagnostics Testing?

Diagnostics or diagnostics testing is a fancy term used by auto repair professionals. It is essentially a check-up for your car. These testing procedures can uncover problems with your car before they become costly repairs or leave you broken down on the side of the road. 

What Is Diagnostics Testing & What Gets Tested?

To understand what diagnostics are, you should understand the evolution of the modern car. Most vehicles nowadays are simply computers on wheels. They have various built-in processors, microchips, and sensors to monitor all your vehicle’s processes, even when the engine is off. They all have specialized software, which requires the usage of diagnostic tools and equipment to decode. As a result, the scan tools can detect problems from all areas of the car, including the engine, transmission, emissions system, brakes, and more! 


It is important to note: When a technician reads the code displayed on scan tools, it only points the tech in the direction of the problem. It requires a professional mechanic with the right skills and expertise to look at the problem more in-depth. 

What Are the Advantages of Diagnostic Testing?

Before diagnostic testing became a major service offered at auto repair shops, identifying car problems took longer (and as a result, cost more). Now, the process is much quicker for technicians all around. Plus, diagnostic testing gives professionals a clearer understanding of the true conditions of the problem. We can uncover problems way sooner before you can experience a breakdown.


Diagnostic testing is a useful tool and practice whenever you have dashboard warning lights, want to buy a pre-owned car, or are generally curious about how your car is doing. There are many reasons why someone would want diagnostic testing done.
