Diagnostic Fee
For some reason "diagnostic fee" has become a buzz word/phrase, making people cringe or cry. We get it! We definetly live in a word of hidden fees and upcharges all around us. However, a diagnostic fee is not in the same family as those "other" fees we see out there. In fact, the most important dollars you give to a shop should be for diagnostic because if that is done correctly then it can save the customer money, time and frustration. But, done wrong and cuss words prevail.
In order to properly diagnose a vehicle's issues it requires experience, specialized tools and expensive information, not to mention all the training and study the technician has payed for and gone through. It can require time to research and understand ever changing systems on cars. With that in mind, in a typical shop the diagnosing of vehicles is placed on the shoulders of the most seasoned and knowledgeable technician. In fact in many shops there is a technician that is dedicated to just diagnosing.
So why has the diagnostic fee become so dreaded? One idea is that part stores like Oriellys and Autozone and Advanced claim they can diagnose your car for free just by plugging in their scanner. If this was Mythbusters that ideology would be "Busted". The code that has triggered the light to come on is vague at best and only indicates a system or sensor that "could" be causing the issue. Example: A 2010 Dodge 2500 comes into the shop with the check-engine light on for a fault with the CKP ( crankshaft position sensor). The customer has taken it to the above named part stores and thus has replaced the CKP, CMP, connectors and some cables because the part stores "diagnosed" it for free. A trained, experienced technician then spends the appropriate time and attention to properly diagnose the issue. He finds that the alternator is bad, sending AC current back through the electrical system causing the computer to think there is an issue with the CKP. The shop replaces the alternator and verifies the issue is resolved.
It would be really convenient to just simply plug in a tool and the diagnostics is all taken care of by a computer. However, with all the modules, sensors, wires and systems on cars today proper diagnosing is even more complex then before.
