My abs is kicking in between 10-20kph (6-12mph). Not all the time it seems fairly random. The light comes on along with the parking brake light. Has anyone heard of this?
2010 f150 supercab 5.4
Any helps apreciated thanks

 

I haven't had this problem but the only thing that comes to mind is a bad ABS sensor. I guess it could also be a short somewhere in the ABS system

 

have the ABS code read.. there are sensors on each front hub and a rear speed sensor which sounds like your problem.. speed related.. to be sure.. have the code checked.
