No problem. Here’s the location of connector I200, and all of its contents on your particular truck. Hope this helps!
C2200-49 can most likely be due to a blown fuse, high resistance or open circuit in a battery feed or ground circuit to the ABS module, or a failed module itself. While module failures aren’t impossible, it’s more likely there is a circuit fault to it. Think back to the I200 in-line connector: the vacuum pressure sensor circuits run through there, as do the brake pedal travel sensor. These can skew the ABS module if anything is off and cause it to set codes, I’ve seen it before. Your power feeds to the abs module run right to the pdc, at fuses 06, and 26. Ignition run/start signal comes from fuse 76, and runs through an integral relay on the pcb of the PDC. G101 ground supplies the abs module and is located on the left front area of the engine bay, down low. Check and clean that too. If everything checks out, remove the pdc and inspect pins 1,26,and 32 of the C3 connector under the PDC, which is a long black rectangular 42 cavity connector. You might find some green corrosion at one of the pins, or even burnt/discolored material. As for the U code, that sets in the EPS module when there is any ABS dtc set as active. Let us know what you find! I’m determined to help you out on this one.
I ended up having to take it somewhere to confirm if the module was bad or not and they confirmed it. I tried my best with the info you gave me to see if there was some sort of short but I could find anything so figured it was best to take it to a pro to look at it.
