Here is the bulletin I was after as I copied below. Now since you have replaced the effected hub already with the condition still present, Or I assume the condition is still active? It takes a special scanner to erase ABS codes. If the condition is still current I want you to purchase a connector pigtail for that hub which is the drivers front, and replace that connector with the wire kit available through Acdelco.
That should fix your problem>

This bulletin is being revised to change part number information and update the model years. Please discard Corporate Bulletin Number 03-05-25-004 (Section OS - Brakes).
Some customers may comment that the ABS and/or traction control system lamp is illuminated. Also, the AWD disabled message may be displayed. Upon investigation, the technician may find several DTCs set.
When normal diagnosis leads to the wheel speed sensor as the suspect component, replace the front wheel bearing and hub assembly, P/N 89047684. Refer to the Wheel Bearing/Hub Replacement procedure in the Front Suspension sub-section of the Service Manual. This new part has 6 mm (0.236 in) added to the harness to prevent any stress to the wiring.
Parts are currently available from GMSPO.
