ABS trouble

I've searched the forum and haven't found a conclusion, so here it goes.

​​​​​​Long story short I hit a dip in the road pretty hard today, and my ABS light has been on ever since. I have the codes:
C1266
C1230
U1900

To me, these codes would indicate a wiring issue. I checked everything I could and nothing seems out of place. The ABS Fuse in the passenger foot well seems fine, and the wheel speed sensor connectors all seem fine. I'm not sure how the plug on the abs sensor comes off, so I didn't want to mess with it before posting. Any help would be appreciated 😀

Did you check the tone rings?

It would help if you identified your truck.

Sorry, I thought my truck description was in my signature. 2005 f150 xlt 5.4 rwd. I don't think it would be a tone ring, because the light is on all the time, and only goes off when I shut off the truck.

You don't have a signature displayed (and no, I'm not a cell phone with a mobile app).


From the WSM:

C1230 Wheel Speed Sensor Rear Center Input Circuit Failure
C1266 ABS Valve Power Relay Circuit Failure
U1900 CAN Communication Bus Fault-Receive Error
