e35b lmm balance injector flow rate pids not working?

i bought a 2009 lmm a couple months ago and when i bought it i logged these pids to get an idea of the condition of injectors but i updated everything today and plan on working on a tune for the truck so i tried to log those pids again today and i get $11 error in 7.5 and 0101 i think in v8? all the other pids work. it also shows that all the system tests are not supported. I thought it was my obd connection so i tried to log them in my other lmm and same thing. any ideas?

Nevermind. Turned out to be a dirty connector somehow. All good and going now!

If you don't mind please tell us how you found the dirty connector and how you cleaned it and which connector. thanks
