I'm out of ideas with this thing.....abs activates atslow stops...looking at wheel sensors with scanner I wouldn't suspect them but a visual on the tone rings is ugly

 

if it uses passive abs sensors....if the sensors get pushed back from the tone wheel...from rust....the signal will drop out at low speeds...signal drop out causes the abs module to think one wheel is locking up so it will activate the abs pump. No codes will usually set...check for them however and focus on that wheel if you have one. If no codes...remove each sensor, clean the mounting surface and reinstall. any that are stuck could be the offending sensor.
check for cracked tone rings if they are on the cv shaft

 

Only thing that's getting me is that if I watch sensor speed on scanner they never drop out and are always consistent speed with the other ones......another thing is theres a reference voltage on the same screen as the sensor speeds and it bounces from like 4.1 to 9.9 volts constantly....the front tone rings look horrible from rust but being that the sensors read like they should I didn't think they would be an issue

 

had a look at service info...your system uses active sensors so what I posted previously would not apply
