Need someone with in depth ABS knowledge

[Joelvv]

Working on a 2000 CCLB K3500. Has a 310 module like the rest of them, and I keep getting C0265, which is common on the 325 module from what I understand. Isolation and dump valves all work, and the motor runs when tested with a Solus Pro. If it's all working, why am I getting this code?

I’m not sure which brake control module was used on the 98 (other than it being a Kelsey Hayes), but here is the diagnostic for that code for that year. Maybe it will help.
