2018 Ram 2500 6.4L Hemi No Power

[Coach BDawg]

Okay. The other day I was driving down the road and my break light came on. (I thought this was weird) I reached down to pull my break release just in case I hit it. A little further down the road my windshield wipers started running and by time I got home I had lost all gages and also got a no fuel pressure notice. Turned into driveway and the gages were jumping and the area that gives the notifications was flashing dim. turned off the truck and tried to restart. Nothing! When I would open the door the gages would bounce and the light on the dash would flash dim. Key no longer activates the locks.
Had my mechanic come by to see if we could get a code. Nothing because the ignition switch has to be on. We decided it must be the TIPM so i ordered one. Came in today so we installed it and nothing even after following the instructions on a hard reset.
Has anyone had this issue or something remotely the same? We are at a loss!

How old is the battery?

 

[Burla]

sounds like it could be win as well..

Dodge Ram WIN module cheap fix (won’t start)

Instead of replacing WIN module just bypass the start function of it by using a push button switch wired into the start relay

What happens if you boost it,but as Burla says,good chance it could be the Win module

 

[Coach BDawg]

Nothing. It's like the computer isn't communicating with anything.

 

[Coach BDawg]

I am doing another Hard reset on it over night to see if that helps. Thats what the manufacturer said to do.

 

[Coach BDawg]

Problem is we can't get any codes to figure out what direction to go. Truck only has 120K and really disappointed with this truck. been one issue after the other.

Start checking connectors. I would start with the big BCM connector above and to the left of where your left foot rests while driving.

I've accidental un-latched that connector before and had symptoms just like you are describing.

While you are under there, look for any aftermarket stuff previous owners may have installed. Alarm systems, remote starts, etc. Those can be problematic, especially if the install required cut or splice wires.

 

[Burla]

When the win modules fails = no codes, the truck "thinks" you turned it off. Look up YouTube's on how to clean them.

 

[Burla]

When those contacts get corrected from use all you need to do is sand them. Like a carbonized film gets on them and you need to get them back to copper.

If your dodge win module isn’t working (vehicle doesn’t start) chances are the contacts are making good connectivity. Remove it from the vehicle and take it ...

If you buy a new win you will need a flash and program fobs. If you have a little skill try and clean them.

Turned out to be the transfer case control module.
