[QUOTE="Mtmccue12, post: 1447955, member: 27913"] I bought the truck new and at about 2,000 miles, i **cough cough** changed some items i deemed to be harmful to MY truck. I use a Sct x4 tuner from truckwurx.com. I now have almost 9,000 miles on the truck and it's run flawless until recently when I got a U0074 code. Which is "Control Module Communication Bus B Off" After my research, ive concluded that it's most likely moisture that's gotten in to the open electrical connectors....such as the Nox control module. Since then I've: Cleaned and greased all electrical connectors Removed nox control module Checked the fuses I keep clearing the code only for it to come back the next startup I've also noticed that the glow plug light on the dash doesn't light up now Does anybody have a solution or experienced the same problem? Any help will be greatly appreciated [/QUOTE]
