Just purchased this truck a month ago in Canada, now display came up with check engine light error code 1 with red triangle, can't get fault codes to come up. Brought it to road service and they could not pull up the codes, now truck will barely pull my load display reflects no manifold pressure egr valve. I have new fuel filters put on no difference... Just starting out on the road again and need to minimize expenses and avoid a searching expedition.... Thanks

Engine has most likely derated horse power 50% due to fault code,,some times you can disconnect the batteries for a minute and the ECM will reset,,try it might help you get it down the road a day to two

If you have red triangle light on it's really bad. Don't take to the road or consequences will be too expensive. Take to the good shop and get it fixed.

Thank you guys, upon more investigation, triangle is red with parking light on then turns yellow. I've got a guy looking at it now and it appears its the middle DPF sensor, not getting to right temperature. Will update if it turns out to be anything else. Thanks again!

Was this a fleet truck by chance? We have had several that had a PeopleNet, Qualcom, etc. that we could not hook the computer to. They unplug the data link behind the dash to hook the system up then the system plugs back into the diagnostic port. In many cases, when they took the system out, they forgot to plug the diagnostic port back in.
pearcetrucking Thanks this. -
I also just got a 2010 386 with Cummins. There is a lot of good free information on Rawze.com.
There is a lot you can do yourself to stop those alarms. Also look into getting INSITE. Grapeape's post is interesting too. -
