I thought the OBD programs were mandated by the Government. I do know that many manufacturers have proprietary software to enhance the 'normal' OBD diagnostics. I do have a fairly decent scanner and it does not have the memory to capture a significant time window BEFORE and AFTER a triggering event. Most scanners offer either a fault tree starting with a specific code, or they offer an off-line search with a fault-tree: neither of these would permit the detailed analysis described. At $100/hour with mechanics getting paid based on a flat-rate book, there is no incentive for the mechanics to troubleshoot. A good mechanic can beat the 'book' by 3 or 4 to 1, so like a lawyer, can actually bill a hundred hours in a 40 hour week - no time in that schedule for detailed troubleshooting. Intermittent problems are the bane of a mechanics life - often call-backs must be performed at no cost to the customer unless it can be shown to be the service writers misdiagnosis or something.
@William: Exactly, and that is when the problem occurs. You do need to get the information documented properly. If not the same kind of issues will rise and the next generation of the users will suffer.
@GTOlover: Yes indeed and the issue is when its being used to cater other industries as well. I think the best would be to have a customized model where you can drag and drop based on the requirement. Anyway still it will not suit the exact requirement but definitely will be much more user friendly.
The diagnostic component that enabled finding that problem was the service persons MOND, coupled with an excellent understanding of how the system functioned and how it was supposed to function. Without that understanding the best a service person can do is change parts based on the diagnostics in some service manual. Some manuals are very good, some are nearly worthless.
Actually, this is a fine example of following all 9 rules in my book Debugging. Mark (1) Understands the System (clearly!), (2) Makes it Fail (with test drives), (3) Quits Thinking and Looks (by recording a movie), (4) Divides and Conquers (by noting that the engine runs fine and thus "ruling out the obvious" engine component issues), (5) Changes One Thing at a Time (by test-driving the vehicle cold like it was during the reported failure), (6) Kept an Audit Trail (actually, the car did this with the freeze-frame at the times of the failures), (7) Checked the Plug (by making sure that both sensors saw the O2 spike, he proved that neither of the sensors was blinking out), (8) Got a Fresh View (by doing research and discovering the air injector), and (9) He Did Fix It, So It Was Fixed (sort of -- he had every reason to believe he found the cause, and the car, which consistently failed before, now consistently runs. This is one of those cases where putting the old part back in and seeing it fail would be overkill.)
It has been my experience that good debuggers/troubleshooters inherently follow *all* nine rules, consistently. And as described in the war stories in my book, ignoring even one rule often results in long, fruitless debugging efforts.
I'M JUST A CRAZY OLD COOT WHO WATCHES FOX NEWS ALL DAY AND BELIEVES EVERYTHING THE OIL COMPANIES TELL ME ABOUT CLIMATE CHANGE BEING A HOAX BECAUSE I CAN'T ADMIT THAT I'M WRONG AND I THINK OLD CARS THAT GO REALLY FAST AND DESTROY THE EARTH ARE GREAT BECAUSE HALF A CENTURY AGO THEY HELPED ME PICK UP CHICKS, OR AT LEAST THAT'S WHAT I TELL MYSELF BECAUSE MY EGO DEMANDS IT AND I CAN'T CHANGE MY OPINIONS BECAUSE THE GUMMN'T IS EVIL BECAUSE OBAMA!!!!!
Yup, you're a "toe tag" liberal, totally refuse to answer the issues as stated as if they were "beneath" you. You guys wouldn't have a chance if the mental level of the average voter nowadays weren't such that they think "The Daily Show" and "Coast to Coast AM" are NEWS PROGRAMS. And thinking that in order to get us over to this "shortstop" to socialized medicine (at these HIDEOUS price points for insurance policies!) you don't even need a website that works, you just need a few decent commercials and a good sales campaign?? Good luck with that ideological "echo chamber" after the electorate STOPS behaving like the cast of one of these popular zombie programs - like, say, this November...
What's wrong with regulations if they make the world a safer place? I remember as a child before the Clean Air Act that there were days that the smog in LA was so bad that you couldn't see 100 yards through the haze and breathing was painful and difficult. Since then, the air has become much cleaner and more breathable, but why burn fossil fuels at all when wind, solar and ocean wave/tidal generation could replace most of the electricity needed to power electric vehicles that are perfectly suitable for 95% of commuters (e.g the Nissan Leaf)? Of course, a lot of that electricity is currently generated by burning fossil fuels, so we need to build the infrastructure to generate and distribute more of our electricity and the increased demand that electric vehicles will create, but market forces are already bringing about some of the change, and moderate subsidies on the installation of solar/wind/ocean generation by the federal government could easily make (are already making) those technologies competitive.
Government policies are not making fossil fuels obsolete; they are already obsolete but because our infrastructure (and trillions of dollars of profit) are at stake, the fossil fuel industry is fighting tooth and nail to prevent the inevitable. But fossil fuels cause immense damage to our health, infrastructure and environment, so calling them "inexpensive" is not correct. Even if you were to power vehicles by burning fossil fuels, it is much more efficient to burn them in a large-scale commercial plant and distribute the energy as electricity to vehicles; the widely varying conditions under which vehicles operate makes clean, efficient combustion much more complicated that in a stationary generating plant.
Finally, I'm an engineer; I'm not driven by ideology but by evidence of what is the most efficient way of doing things, taking into account the totality of costs including externalities.
