Hoping someone might have some more info on this code. Plugged the laptop in the other day to see if the p1000 was gone yet so I can go get my emissions testing done and it came up with a U1900 code twice. I know that it is a CAN communication Bus Fault - Receive error. It is listed twice, one seems to reference $769 and the other $768. I beleive these are referencing different modules but not sure which ones. Did some searching and this seems to be more popular with the 6.0 power strokes. I would appreciate any input any one has. Not throwing a CEL and the only other code was the p1000 ( I recently switched tunes)
