diagnostic machine on an engine

Here at South Mountain Collision & Auto Center in Middletown we often do diagnostics and sometimes the problem is obvious after hooking the car up to the computer and reading the codes.  However, sometimes it isn't obvious during a test drive or after hooking it up to all those computer programs!  You know there is a problem and a Check Engine Light is on with the fleet customer telling you the car has been having issues starting and the light has been going off and on depending on several factors.  No pattern, no simple answer but the problem becomes obvious when you start following the "threads of the issue" thanks to all that ASE Technician training.

Whether you drive a Ford, Chevy, or Ram diesel pickup, it’s especially important that you always seek high-quality repair and maintenance from qualified professionals. At South Mountain Collision & Auto Center in Middletown, MD, we specialize in diesel vehicles and the ins and outs of diesel servicing. There are plenty of shops out there that can replace a part or perform a job, but it’s important that the technicians doing the work know what they’re doing, why they’re doing it, and are doing it right.
