ThanX BriteWhiteRam I appreciate your posting of code translation.. It is a start ad can now consult GMC to see if it's major or minor. Like to know ahead of time before saying there's a code, check and let me know. They can say anything if you don't know the code before hand. ThanX again!

 

DTC P0677

 

Any idea what this code indicates? Thank you!

Also have seen codes P0202, P0203, P0205, and P0208... I know they have something to do with the cylinders.. but not sure what or what fix.

 

0687, I know its high ECU voltage? Any hints on where to start to figure out why its getting high voltage? The alternator is putting out right at 14.

I also checked the ECM relay and its fine

 

When the transmission downshifts from overdrive to 4th it sets a po700. It is when I'm
pulling my fifth wheel only. I have to pull over and turn the power off to get the tranny out
of limb mode. Any suggestions will be greatly appreciated.

 

I have a 2006 lbz with efi live, air dog, ats trans, with my efi live if I am on a low tune under 80 horse no problems, as soon as I go to smoke, econ, or power if I hammer on it it starts bogging down until I let off and idles like crap for a few seconds and throws the code ecm u1096. I can clear it and it stays away but if I hit it again it comes back. if I am on a lower tune and hit it it functions properly?

ive also gotten a p0202 injector circuit error and I think it was a po396 or something about generator failure
but 90 percent of the time when it bogs and trips a code it is the u1096

 

2011, Sierra HD 2500, New pipe from turbo back, def tank gone, EGR gone, Banks cold air intake w/ super scoop, A50 trans. TCM download. Presently using the heavy tow tune. After downloading EFILive I get a P1082 trouble code. I have a list of the codes, it appears there are no codes 1001 up to p1105. Thank You in advance
