What Happens During a Car Diagnostics Test?

August 25, 2022

A car diagnostics test is similar to a vehicle inspection. However, this type of diagnostic tool focuses on your car’s internal computer and is typically a quicker process than a full vehicle inspection. A car diagnostic test helps find issues with your vehicle that can be explored in more detail later if necessary. This test is clearly a valuable tool for finding potential problems, but what happens during these tests?

Diagnostic Test | TRC Automotive

A car diagnostics test uses software to examine parts of your car, including the engine. This is made possible due to sensors, microchips, and more that are present within your car. During the test, various parts of the car, including the engine, exhaust system, brakes, and more are examined, and the ignition coils, the throttle, and more are also looked at.


After a potential issue is located, your technician can look at problem areas more closely to see what specifically is causing issues with your vehicle. The car diagnostics test combined with your technician’s expertise can help you get right down to the issue, allowing you to know what next steps to take for the safety of your vehicle.
