Todays vehicles are very complex with computers and wiring involved to run those computers. It is getting harder by the day for a general repair facility to perform proper diagnostics of computer controlled systems.

We compare it to bringing your transmission problems to a transmission shop because that is all they do. Now they even call us because of the electronic complexity involved in todays transmissions.
