Code U1900

I have a 2006 6.0L F250. I was pulling a trailer today with a small excavator on it down the highway at 70 mph and the wrench light came on. I have had this happen one other time hauling a trailer. I lerft the truck on this time and ran the DTC and got the U1900. What does this mean? What can i do to fix it? The truck misses at times at WOT, but does it randomly. But even when that hapens, the light doesnt come on and it doesnt go into limp mode. If you shut the truck off and start it again, it'll be back to normal... If that helps any

Possible Causes
CAN circuit 1908 (WH) open, short to ground, or short to voltage.
CAN circuit 1909 (BK) open, short to ground, or short to voltage.
DLC C251
ABS module
ABS module C135
instrument cluster
instrument cluster C220b
PCM
PCM C175b or C1381b
trailer brake controller
trailer brake controller C2142b

Things to check first:
You could have a bad ground on your trailer.
Your cable on your trailer could be too short and causing it to pull out of the plug
You could have a short in the factory trailer harness wiring
The plug could be gunked up

Also, check for loose fuses:
#11, 10 amp: Speedo bounce, ABS light, Cruise control inop; Codes U1900, U2023, P0500-P0503
#12, 2 amp: Cruise control inop, TBC Fault displayed, chime; Code C2803

u1900 more thenk likly means what your reading codes with is not see what the real code is.
u1900 is a network falt.
you need a scan tool with the latist dtc files to read those codes that kick the wrench light. then its still iffy if you can.

cheezit -

Why couldn't bad trailer wiring (ground issue, etc) cause this code?? Or is it more likely to be a false code?

Sorry to undig a dead thread... since the beginning, I have gone through the top end with studs, and cleaned the turbo. The wrench light no longer comes on but on long hauls with a trailer, she sometimes likes to miss on the top end. Sometimes. Almost like it starves for fuel. Others, its perfectly fine. Fuel pressure is at 68 psi and stays there even at WOT and an sct tuner. Also have a AD2 and blue spring. Code is still there and my a/c no longer works... wonder if they are related in a way
