2006 Envoy SLT - C and U Code issues

2006 Envoy SLT with approx 178k.

When slowing to stop (gradual stops), I hear and feel the ABS system engaging. I read the codes and get the following:

C0245 (Wheel speed Sensor)
C0455 (Front Steering Position Sensor Circuit)
U1064 (Lost Communications w/ Body Control Module)
U1016 (Loss of Comm ECCM)
C1026 (Loss of Comm Auto Transfer Case Control)

I'd like to resolve the ABS engagement issue first off but I'm wondering if the other codes were caused by the ABS issue, or the other way around. Thanks in advance.

Fix the abs code first, bad sensor or poor connections.
