    What to do with extra High Speed GmLAN lines

    Sorry for the late reply had some trouble with my account signing out. No, we have a budget tool don't even remember the brand, it's worked every time before, but When plugged into obdii, it just reads error1 which means it can't communicate with the modules. Dunno if that also means modules...

    What to do with extra High Speed GmLAN lines

    Ok, so I have some good News and some weird news... Good news is she cranks, and runs, but only when the relay is fired manually, Its in the picture attached. So a few issues have arisen and I cannot figure out what is going on. I drew out how I rewired the circuits. The only wire powered...

    Getting 12v at duramax fuse block, but 3v on Avalanche body.

    Turns out my body ground was gone, dunno how or why, but it was missing. Everything works now except for when put to crank it just clicks the relay. I'm running an LMM ECM, and it doesn't have an enable wire like the LBZ does. I relocated all the correct pins, so that it is wired for the lmm...

    Getting 12v at duramax fuse block, but 3v on Avalanche body.

    Well, title says it all pretty much. I'm still trying to figure out my 2012 Avalanche/duramax swap. Finally got everything sorted out wired up, and even put power to it. This was last Friday, and it was great, lights on the dash came on, all the interior lights, and everything seemed to be...

    What to do with extra High Speed GmLAN lines

    Yeah, with the new diagrams and your advice things are finally falling in place. Should have it turning over and this week. I was actually talking to my boss about that one. He mentioned that now that we've done it once if we ever did it again it would be simpler, but I said to him just go...

    What to do with extra High Speed GmLAN lines

    Okay, so I bought two other licenses on Mitchel diy and the good news is yes you're right, there is no j1939 running in the LBZ, but no, it does not have a wake-up voltage. The LMM harness however does. This doesn't post too much of an issue, except there's wake up voltage going to the lmm TCM...

    What to do with extra High Speed GmLAN lines

    Okay, I'll look into that. The wiring diagrams I have must be from an lly or something. I have found that previously on Mitchel diy. Maybe that's why it's confusing. I did a keyword search for "wake" but nothing came up. The dmax wires might be labeled as something else, so I'll look again...

    What to do with extra High Speed GmLAN lines

    Yeah me again, with electrical. Again :| So I'm almost done my LBZ to 2012 Avalanche transplant, but I've run into yet another problem. so the J1939 lines for LBZ are all self contained in the engine harness and only go between the ECM TCM and GCM. @kidturbo gave me some insight on how to use...

    Gauge DIC from 2012 Dmax with 08 ECM compatibility?

    Ok, thanks man. I'll just roll with it for now see what happens. The truck is getting an auxiliary gauge cluster on the driver pillar with boost and all that stuff I might just run an analog oil pressure or something and call it a day if it comes to it.

    Gauge DIC from 2012 Dmax with 08 ECM compatibility?

    Hey Guys, to preface I'm swapping an avalanche body-on-frame not transplanting. so far everything has lined up, and I was able to sort out my engine CANBUS problems with great help from @kidturbo, and @duratothemax. I have an 06 LBZ running on an LMM computer using GMLAN to communicate with a...

    Avalanche body on Duramax frame wiring

    ok, I actually thought he was referring to a literal sensor bank somewhere on the engine lol, my bad. I should have read it twice would have probably figured it out, thanks.

    Avalanche body on Duramax frame wiring

    Thanks for the info! That's much simpler than I thought. I'll look into the ECM, and I'll figure something out. Hey, dumb question, I know what you mean by MAF and MAP, but I don't know exactly what you mean by sensor bar 😬. Nothing consistent shows up on google when I search for it.

    Avalanche body on Duramax frame wiring

    Will I need the LMM TCM as well? Or is it just plug and play between the LMM ECM and the LBZ TCM?

    Avalanche body on Duramax frame wiring

    Hey Guys! A lot of posts here have been great help to me, but I need more tailored information from the seasoned and learned members of this forum. I am putting a 2012 Avalanche on a 2006 Duramax rolling chassis, but I'm unsure about the compatibility of the body modules to the Duramax ECM. I...
