Hey it looks like I cut out all the down under cars except a few 2007 cars.
Sorry. I will try to edit them back in.
If any one want to add to it please do. I like the TIS Disc #
01-05 GMT800 ECM-TCM Comms is CAN (J1939), not GMLAN... 06-07 GMT800s are GMLAN. JustFYI (Otherwise I could make a 06 TCM work in my 04 easily). Dont see LB7's in there...
CalEditor, I appreciate you uploading these, but I fear these might be copyright documents, happy for you to put a link to an off site host.
I'll be pulling them down directly off our server in 24hrs.
Cheers,
Ross

LLY's are E60, no clue what LB7's are. I should be able tell you when I get an LB7 ECM though. Like I said, I'm 99% sure the E60 uses J1939 for ECM/TCM/GPCM/FICM comms; IIRC, connecting the A40 GMLAN pins to the CAN bus crashes the bus causing all kinds if problems (Codes, no-start, floods, plagues, death and destruction); I could probably try it this weekend and see what happens... I've never done it, but someone else that has been tinkering with the A40 did.
Edit: According to Mitchel Ondemand5, 2005 (and 2004LLY) Duramax uses a "SAE J1939 Serial Data Bus" (CAN) for the ECM, TCM, FICM and GPCM inter-module comms. Apparently, the Hybrid (If it exists) uses GMLAN for ESB/SGCM/EHPS/HCM/PCM comms.
