GM TECH2 scan tool and OBD2TOOL seller
Well the cheap scan tool evidently will not reset the TCCM on my 08 LMM, it looks like it should but when the reset button is pressed nothing happens, I have tried enough TCCM modules that I am confident it is not a bad TCCM and the vehicle was working fine before I pulled the TCCM to use as a...- Mogman

LMM stand alone loss of power no codes
I have been eliminating the codes as advised, the last ones before today was the alt L lead, the AC codes and the fuel level codes. I ended up abandoning my weekly trip to the beach this morning as the DuraVee kept going into limp mode and giving me a P2463 Diesel particulate soot accumulation... -
LMM Allison 1000 shift options stand alone.
Really is not enough room for the BCM, the dash area on the HMMWV is very small- Mogman

LMM Allison 1000 shift options stand alone.
I think there is significant differences, for example on the LBZ the TCM tells the TCCM it is in neutral with a single wire signal, on the LMM it is conveyed via data on the high speed LAN. (this I learned from a small company making a complete stand alone TCCM setup) I am thankful the...- Mogman

LMM Allison 1000 shift options stand alone.
I looked at the connector views on both the BCM and the TCM but could not find anything that looked like tap up or down, the cruse control and the tow/haul swich are on the BCM in the LMM.- Mogman

LMM Allison 1000 shift options stand alone.
No I do not have a tap shifter, When the LMM came out they moved allot of what other modules were doing to the BCM for some reason, I think that the shift control switches were connected to the BCM, of course I hope I am wrong.- Mogman

LMM Allison 1000 shift options stand alone.
On my LMM stand alone install I have 4 "drive" shift positions marked OD, D,2,1 if there is a 5th position I cannot shift to it. I am using the transmission shift detents for reference. The OD and D position act the same, good all the way to 6th gear, the 2 and 1 position only give me 1st gear...- Mogman

LMM stand alone loss of power no codes
Interesting! From what I could glean from the bulletins the issue may be the incorrect calibration of the MAF like I am hitting her too hard when cold. I have still not found out what the original intake ID is where the MAF is mounted, I guess it would be easy enough to pull the intake from my... -
LMM stand alone loss of power no codes
Had a real nice run to the beach this morning, turned over 1150 miles on the conversion, no limp!! the 4WD worked flawlessly, with almost 800lb more weight on the front axles it really bogs down in the soft stuff in 2WD, and really performs well in 4WD, I did get a MIL just after hitting the... -
LMM stand alone loss of power no codes
Yep,turned it off and did a tune flash and both codes went away and the MIL light is off! two trips must be why it did not appear right away. THANKS to all for the help!! I will give it a good test Saturday when I run down the FWD section of South Padre Island, probably not too far, as it is 60... -
LMM stand alone loss of power no codes
I went on a 50 mile jog this afternoon, and it ran well and I had made those changes and now I am only pulling U0106 and P0381 codes. I do have U0106 set to "not reported no MIL" so it must be the wait to start lamp failure causing the MIL. -
LMM stand alone loss of power no codes
I am a little mystified as why the ECM is not complaining about the loss of comms to the BCM, brake controller etc. -
LMM stand alone loss of power no codes
Also I am now getting a U0106 so I assume I can kill that TDC for the glow plug controller also? ALSO the MAF tube came with 76MM and 89MM calibration inserts, what would the correct ID be for the LMM? AND is it OK to edit the turbo position tables to get the decent idle back? dang thing... -
LMM stand alone loss of power no codes
So for example if I set C1909 for 8000 RPM and 1913 to 200 it will never do the tests yes? -
LMM stand alone loss of power no codes
I have not made any adjustments yet, I will set those codes and look at the tables For example what should I do with C1901 since there is no EGT sensor? All zeros? Thanks!!! -
LMM stand alone loss of power no codes
NO LIMP!! I took it for a drive AS IS and she seemed to run perfectly, I was surprised with the 4.92 gear ratio and 37" tires the error at 60MPH is only 3MPH over the 3.73 and stock 1 ton tires, it actually shifts a little better. -
LMM stand alone loss of power no codes
Thanks, I will try to make those changes -
LMM stand alone loss of power no codes
Thanks, I wonder if the same procedure works with the frequency type of MAF, seems it would. I don't think I am going to re-scale yet as the truck ran fine for 700 miles so I would not think that would be my issue at this point and do not want to add any more flies to the ointment.
