Grading braking enabling automatically after wheel bearing replacement

[tko500]

Hey all... 2014 2500HD in question here.  Noticed over the weekend the front wheel bearings had excessive play and replaced both with GM bearings purchased from the local dealer.  These bearings are complete with ABS sensors.  

 

After replacing the wheel bearings I am driving down the road and the grade braking kicks in at speed on level ground at 45 - 50 mph.  My first impression was something questionable about the wheel bearings, but after speaking to 2 local dealers they both say there is no correlation between the wheel bearings and grade braking activating in this manner.  Curious to hear if anyone has any thoughts or similar experiences.  Also open to hear what to look for in hopes of getting this resolved without going to the dealer.

 

Thanks in advance.

Any OBD2 codes? Did you try disconnecting the negative battery cable for 30 minutes?
