2003 Sonoma ABS dreaded C0265 code

[ymurf]

My daughter just bought a 2003 sonoma 4x4 automatic 4 door from my uncle. The ABS light and brake light were on so before I bought it I took it to my friends cause he has a good code reader. The code came back C0265 which is the brake control sensor error which I hear is very common. My uncle said it use to come and go but has been lit for awhile now and my buddy couldnt clear it but my uncle gave her a good deal so we bought it. She picked it up today from him and holy cow the lights were not on.Well its starting to sleet and snow here in Missouri and awhile ago she was driving it and the back tired slipped a little when she pull out of a parking lot and all the sudden the dang abs and brake light came back on again.Was this just a coincidence or did that have something to do with the abs light coming on? What should I check to fix this?

I would suggest a full scan with an abs function scanner to look at the entire system, then decide what to do.
