Hi All, first post with my 2011 3500 SRW
It has 68000KM on it and the Check Engine Light came on.

The next day while on the highway at about 125Km/h, the red "attention" light came on and lost power for a few seconds, then power came back after I slowed to about 100Km/h. This happened 3 more times in the same scenario. A day later the light went out and all was fine. Then today the Check engine light came back on

I scrolled the forum and figured out how to use the key to pull the codes.
Here is what I got, and what I tried to figure out via the web.

I took these codes when the truck was sitting for a few hours in the cold

P0562 - Low voltage
P061A - Low Barometric pressure
P2A01 - O2 sensor?
P0606 - ???

Looking for some knowledge/recommendations from the experienced!

Thank you!

 

How old are your batteries? Are the battery cables free of corrosion from the batteries and there is no rust or corrosion on any of the connection point?

The Ram electrical system is a CAN-Bus type of system were multiply electrical signals are sent over the wires for different components to function. So a very good charged battery is required to allow the system to function correctly. Have your batteries load tested and if one is sub-par than replace both. If the batteries are good than check the battery cables making sure they are clean with no breaks and or corrosion in them. Next check the alternator output and connections the last thing to check is the main wiring connection to the TIPM box in the engine bay.

Report back if this helps or not.

Thought it was spelled CAN-i-bus?? Hmmm.......
