I removed mine and installed a manual valve in its place for same reason. Mine was pulling 1 amp or 24 ah per day. 

Ive had same issues decrypting the scangage codes with no luck. Last time I called them they sent me to bigdieselcodes.com but that didn’t help either. 
 

on my coach i have 2 switches under /inside the dash  by steering column labled diag and idle, heres my notes on how to use them to display the codes by flashing the CEL light, these will be cummins codes easily found online. Hope this helps 
 

To check DTC: Diag sw show’s first code then idle up sw show next etc

Yes I replaced mine about a year ago, had the occasional dreaded dead pedal that kept getting worse. I have the airdog too so far so good. 

I had same issue with SG codes, nothing on google so  I called them they were not able to tell me what they were. They told me to look on truckfaults.com which didn’t help either. Ultimately i changed the injection pump by process of elimination and they went away. I don’t use it for codes anymore  hope you have better luck 

Its also possible something is blocking the flue tube internally.  Theres a heat disperser that drops into the flue tube from the top that can be removed allowing access to the inside. Would have to pull the fridge out to get to it.  And When i worked for an RV dealer anytime we pulled a fridge we always flip it side to side and let it gurgle, they work better after doing this too. 

Goecm.com has some 

What warning light comes on?  The turbo is driven from exhaust from engine loading and a lot of suspected turbo issues are really engine fueling issues. An intermittent crank position sensor or manifold absolute pressure sensor can cause your issues.  There would be a diagnostic code stored in the engine ECM as to which sensor. Or any issues in the fuel system could also be the culprit 
 

if the turbo spins up at all (makes good boost at times) which it sounds like it does, then it could also be either a sticking wastegate or if its a variable geometry turbo then the gate could be sticking.  Either of these causes bypass of exhaust around the turbo making it not spin up. 

Transmissioninstruments.com repairs them. 

The fuse for the TCM (transmission control module) is inside of the VIM module (vehicle interface module) on my allison md3060. Sounds like the fuse is blown or the tcm or shifter module is bad. 
 

my VIM is in the front drivers bay, its a square aluminum box with 8 small bolts holding the cover on about 6 or 8 “ square box

hope this helps

Hi Gerry I would like to take you up on your generous offer, ive been planning to order one for my Norcold for awhile, I would be glad to pay you more than just the the shipping, even $50 would be a great bargain for me. 

My MD3060 tranny temp doesn’t work on scangauge either, i think it requires manual setup on scangauge as an xgauge but I haven’t called them yet to verify, does anyone have one working? Thx Jon

Here's one Chinese Cummins Insite 6 with Inline 7.6  I  don't trust it virus wise and have it on a dedicated computer along with Silverleaf.  The computer will not be connected to the internet ever.  It is not a simple plug & play as you have to go through the setup steps.  I don't know what style diagnostic port you have so check to make sure that adapter is included.

Thank you!

As mentioned, there are many causes for the light and for it extinguishing.  Some codes will keep the light on if the problem is active more than a certain amount of time.  I carry a bootleg copy of Cummins Insite and it is always running when the engine is running.  I can immediately see any codes, run tests etc.  For the small investment you can see the problem, see the Cummins troubleshooting chart and even if you cannot repair it you can tell the mobile tech what's going on so he can bring the part along.  It recently saved my bacon when I lost two cylinders due to a fuel timing actuator.    I repaired it myself and was on the way in a few hours.  It saves all codes, shows if they are active, how many times it happened etc.

Code readers are not all equal.

Hey Hypoxia id like to get the insite like you have do you have any advice? Im having low power issues with my 98 ISB and also would like to create the iso file for backup. Thanks in advance Jon.
