6.7L Cummins Forum

Recently came across this site while researching a problem with my 2007 6.7l cummins.Have already learned more about my truck in 2 days, than the past year that I've owned it! Purchased the truck about a year ago,in the states, and brought it home to B.C. Canada.Truck has been great, but recently I've ran into some issues.... local dealership tells me that the VGT actuator needs to be replaced (works intermitant)- to the tune of $1500.00 cdn. OBD 2 reader is giving me a code # u0100 (lost comm. with ecm/pcm A.) Truck has 41000 miles on it, and the aftermarket warranty I purchased, (old republic) won't cover it.I use the truck to tow a 20ft alum. jet boat, and construction trailer - but it spends most of it's time shuttling me back and forth to work, about 30km each way.Don't claim to be any kind of a mechanic,would appreciate any kind of feedback.....Looking forward to learning more about my rig on your site, thanks

Once again a new member has made my day since it's you that I decided to start this site. I just got done looking at the service manual for our truck and code u0100 (lost comm. with ecm/pcm doesn't apply to the 6.7L.

Rather then use the OBD 2 reader try doing it this way on the truck: Just turn the key from off to on 3 times and leave it in the on position the third time. The odometer will display any and all codes and when it's displayed them all it will show ------- and then it will say done.

Welcome to the site and stick around. We have a lot of great members here and oh so much more to learn about when it comes to this new engine

Hey Guys, Off to a great start here.... I know what "off" and "on" is, but can't seem to recieve these codes.Called the local Dodge dealer, and the service dept. tells me it can't be done on my truck.(07' ram 4x4 2500 6.7l, Big Horn addition).Am I really this stupid, or am I missing something here?Thanks for your speedy replies, and warm welcome....

No you are not! mine did not show codes either with that method I had to use a code reader to retrive my codes. OH yes Welcome to the site!

Hmmmm.............well it works on my truck. Just went out and disconnected the oxygen sensor module and kept starting the truck until the Check engine light came on then shut the truck off and did the procedure (Really Fast) and took pictures of the results.
