Mode 6 Diagnostics

[BILLY QLINDO]

Thank you

Thank you again, you are right.... I have the same problem. I will be looking into the program you mention .







Q U OTE=Wheel;33491]If I understand his request correctly, what he wants most is the mode 6 data translated into the plainest possible English, a problem I identify with.
The best, handiest place for this to happen is right there on the scan tool the moment you acquire the data. Having to look it up all the time
makes it so unhandy and impractical to use that the time spent doing so could be far better and more efficiently spent ignoring mode 6 entirely and using other diagnostic input and methods instead. A shame.
While most scanner manufacturers are slowly realizing this problem and
offer some interpretation to some degree, the Automotive Test Solutions e scan probably does it best, and has other unique, very useful features to boot. This scanner is pc based, has a bluetooth option, and would work out nicely on a Verus or Verdict I would think, or on a good laptop.[/QUOTE]

So I did emission testing with obd II and they were making sure the MIL was comanded OFF and no more than 3 monitors not completed. If so it passed. If MIL was comanded on it failed. If more than 3 monitors not completed it was Aborted. If retesting a failed vehicle you can only have two monitors not completed. So I didn't need to understand mode 6 if I didnt want too. However I chose to understand some mode 6 to aid in diagnostics. ie Ford Misfires. Understanding monitors are either not run yet or have been run. And if they have been run they either pass and the MIL stays off with no DTC stored or it failed set a DTC and turned on the MIL. That was more helpful to me when we first went to OBD II emission testing.

Been doing alot of Mode $6 checking after I find codes, permanent or pending. Helps sell tune ups and cure ill-running cars. One thing I noticed on my Modis though was a F250 SD with a 5.4 had 1800 misfires on #7 in Mode 6, but no code, and yes, it showed failed on the monitor. Another thing I've recently noticed was when I will check random mode 6 data, it will show a very high number in the counter, and failed in the test, but still no codes. Was told at a class that if a monitor shows 80% or higher in the count rate, it should throw a code, but this has not been matching up with current experience. Any help guys? And are we as an industry putting too much or not enough emphasis on Mode $6?

I'm not sure if this would apply to Ford but I know on HD GM trucks for instance a lot of monitors are set to not report a code by illuminating the MIL. It probably has something to do with the different levels of allowable emissions and the GVW rating. I noticed this when I used EFI Live/Tune to download the programming from two different 98 HD 3/4 ton Vortec 350 trucks. With that software you can see what monitors are set to trip codes, run at all or are not reported. (you can also modify this if you want). Both trucks were equipped with rear O2's for cat monitoring but it was turned off in the programming.
