Long time watcher of the post, first time posting. I have an 06 Dakota SLT 3.7L v-6 42000 miles. Over the weekend my brake light, abs light and engine light all came on(actually they come on and off). At the same time my cruise control, speedometer and odometer do not work and it will not shift into 4WD(the 4WD light flashes but never engages). I have an appointment scheduled this weekend but I was wondering if anybody might have any clues to help me out? I was looking through some of the threads and it sounds like it might just be some sensors. Any help will be greatly appreciated!!!

 

this doesn't sound like a problem that you can fix at your house, that's for sure! I would say just wait till you take it to the shop.

 

I think I saw this somewhere before. I think it may have been a bad brain.

 

Sounds almost like what Shibby went through. His FCM (front control module) burnt out or something rather had similiar problems as you, take a look...

i had an issue with that when my tuner messed up. dodge had to wipe the pcm clean and reprogram it. your truck might very well need that. there are updates for our trucks.
