Your doesn't take a rocket scientist to use intelligent diagnostics but just maybe there are some technicians that need some extra help. You obviously are way over qualified to use the resources that snap on put in there tool. The point of this post was to show the less advanced techs that this tool can help them and point them in the right direction.

To everybody who responded to this post I thank you for your responses. This post is an example of why there are a lot less posts on a variety of subjects in these forums. Posts are put up to help people not ridicule them or the sponsor. I can take criticism like the rest of them but this post really didn't generate a need for debate. If you would like to debate with me then lets do it in a pm. Would love to hear your theories on this and how you would have approached this topic using intelligent diagnostics....after all..thats what this is about correct?
As Joe pointed out, if the example you used showed something out of whack where there was not these two pids, then perhaps the "intelligent diagnostics" can, and possibly does help.
In the example you used, it's a NO BRAINER.
Actual pid value does not match desired pid value.
It's the expression "intelligent diagnostics" that is bothersome.
I tried very hard NOT to point a finger at YOU, but to continue to defend "intelligent diagnostics" in this case where there are two very understandable pids already available that very clearly show there is a problem, well, I just can't see it being anything superlative.
If you had used another example such as a MAF value at a particular RPM, where there was NOT a corresponding "desired" pid, then you can defend "intelligent diagnostics".
The example you used just isn't.

I agree that snap on should probably start doing this diagnostic walk though. but if one uses some of the oem sw, example, BMW ISTA.. there is absolutely no comparison with the walk though ( test plan ). snap on is on the right idea. but they are about 15 years behind..

Except for the vehicle manufacturer, which is why the control modules perform continuous testing for all critical inputs, each with their own specific testing criteria, and illuminate an (usually) amber colored warning lamp in the instrument panel when they fail, which is supplemented with a diagnostic fault code that can be used (by a competent tech) to determine the correct course of action for further testing.

How many techs do we have here that remember working on and diagnosing cars that didn't have scan tool data?

Remember break-out-boxes, DMM's and oscilliscopes?

That was intelligent diagnostics!

LOL, I remember. I still think in this day and age of ever shrinking tiny gauge ECU pins and wiring , BOBs are making more sense to me than ever before if you wish to save time and don't want to untape and remove connector hoods and risk causing more wiring issues backprobing T pins or piercing wires when you have to test these circuits back to the ECUs. Gone are the days of the old un-shrounded 60 pin ECU where you could back probe a T pin into the connectors with a T pin and not expect to damage anything
" With Intelligent Diagnostics" just sounds better from a Marketing Point of view than "With Active Technician Assist System"
Sort of Like ADAS, that creates lazy , complacent car drivers on Auto Pilot, this is a sort of like ATAS for the same type of techs .
