The Diagnostic Myth:
Many customers feel that diagnostics have been overrated by the repair industry as a way to make more money. They may ask, “Why do you have to charge me for diagnostics? The check engine light is on, so there is a fault code to tell you what to fix.” The truth is, diagnostics is often the most expensive part of what we do at Liberty, but it always saves money in the long run. The check engine light or logged fault code will tell you what system to start diagnosing but it does not tell you what parts failed or, more importantly, why they failed. The word “diagnostic” stems from a Greek word which properly translates to “the art of distinguishing.” It truly is an art to take in all of the information about a vehicle and determine the correct repair path. At Liberty, our technicians use fault code troubleshooting information, electrical diagrams, and the knowledge of multiple vehicle systems to locate all of the failed parts on a vehicle the first time.
