Shade tree engineering will never go away.
The foundation of Shade tree engineering is troubleshooting. Computer based diagnostics can help finding the root cause but can also be mis-interpreted by even the best of computer dedicated techs. Without a common sense approach that has always been a critical part of shade tree engineering, it is not unusal that computer based diagnostics run up the cost by replacing parts that aren't bad. Troubleshooting is always a primary effort, to a fault, because most shade tree mechanics/engineers didn't have or don't want to spend the $$$ to keep throwing parts at the problem until one happens to hit the right spot. That is why they spent more time trying to be sure they have found the root cause.
That doesn't mean I don't see the benefits of diagnostic tools. It does mean, in almost all cases one can still git er' done without them. I can't remember the last time I replaced a perfectly good part unless it was preventative maintenance. A shade tree, common sense priority---pay a small price now to prevent a big price later because many can't afford to risk the big price and it does not pass the common sense test, not a strength of computer diagnostics.
