On an inspection we look at many components, over 50 points. We note what we see as needing attention or it looks fine and rate it from Green, Yellow and Red. We also look at fluid conditions and spark plugs and filters, when appropriate. An inspection allows us to note the condition of your vehicle and see what may need an in depth diagnosis and what components are operating correctly and have much more life.
On the other side, a diagnosis entails just one component or issue. We focus on that issue, following the testing process needed to identify the problem and then suggest proper repair to fix the problem. Diagnosing is a process that takes a great amount of skill and experience. We do use scanners to identify trouble codes in a vehicle. Those codes give us a starting place or what system may be having issues. We start doing our test from there. It is kind of like trying to find a certain house in a city using just the zip code. The zip code narrows the search down. Then knowledge and experience are used to figure out where that house is. It is not as easy as plugging a scanner and having it tell us what the problem is. To add to the difficulty in diagnosing many of the issues we deal with on a daily basis include electrical problems. Today’s vehicles have over a mile of wiring in them, with much of that wiring hidden in dashes, doors, carpets and body panels. A car today has over 200 computers in it controlling all the different systems in a vehicle. Our technicians are highly trained, using expensive equipment to find the problems, before we can begin the process of repairing them.
