2014 ram bcm

[Sgt Superbee]

Hello All,
This seems to be a common problem so I apologize if this was discussed, but I couldn’t find it anywhere. I have a 2014 Ram 5.7 Bighorn and every light on the dashboard is on the fuel gauge isn’t working and had some messages saying the turn signals were not working.
I took it a to a local garage and he believed the clock spring was bad as it was making noise that was changed. Got it back and there was no difference. I’m a Mopar guy several friends and I occurred that it was a body control module issue seeing all the problems these vehicles had I got a reman Body control module and everything is the same. Snap on code reader has no codes except high resistance in the fuel circuit.
Any suggestions would be appreciated. The local garages here are crap and the dealers are worse. Drawing a blank as to where to start again.

If your battery is more than a couple years old...maybe there.

Have your battery load tested , one on its way out can display the same symptoms you are now describing.

Sorry for the late response battery load test ok. Cannot communicate with the scan tool as well says low voltage on the Obd connection. Voltage on c+ to c- on the obd connection only .5. Book says at least 2.5
Battery voltage at the terminals is 12.9. Running 14.2

Pick yourself up one of these old school toaster style battery testors,and load test the battery yourself. 12.9 at the terminals measured with a mutlimeter doesn't tell you,if you have a bad cell in the battery.

I have a 2014 Laramie 4WD 5.7 and I had to jump it off because it hasn’t been driven much lately. When I did get it cranked the check engine light came on and hasn’t went off. I read the owner’s manual and if I understood it right (maybe I didn’t) it said to hook the negative cable up to “exposed metal” (I think that’s how they worded it) and when I turned my jump starter on it arced kinda bad so I turned it off immediately and hooked it up the way I normally would and it cranked. Any idea what I may have done?

Bump..
I am having same problem.. 2014 Ram laramie 4wd 5.7. I killed battery accidently, recharged battery and after recharge all types service lights randomly on. Truck runs normally but chimes all types of codes. Swapped out battery with new. No change. Brought to dealershop. no feedback from CAN, and wants to rip out aftermarket remote start to eliminate that as the cause. I dont believe its is related. So I asked if that isnt the prob then what would be next? He replied the BCM which is on indefinite back order and not available.

update- turned out to be caused by after market alarm poor ****** install job with bad splices and shorts hooked into obd port causing havoc.
After removal and clean up, all codes self cleared immediately.
