What are car diagnostics?

To diagnose is to find the source of a problem. In cars, it often refers to using code readers to determine why the Check Engine Light is on. The vehicle’s control units store diagnostic trouble codes (DTCs) that can help a technician locate the concern and determine how best to repair it. 

But there’s more to it than just using a diagnostic tool to read codes in OBD systems. Diagnosis can be inspecting the source of a rattling or whining noise, determining why your transmission isn’t shifting properly, figuring out why your brakes are grinding, finding the root cause of almost any issue. 

For some systems like airbags, emissions, or ABS, computerized on board diagnostics can be used along with physically tracing wire and testing parts. For others like engine, drivetrain, and brakes, it often requires an in-depth inspection to determine where the fault originates. 

Diagnostics are important in keeping your car operating efficiently, powerfully, and most importantly, safely. It’s always best to have a new concern diagnosed and repaired as soon as possible to avoid additional damage or problems driving.
