When I decided to add auto bed leveling, I updated to the latest stable Marlin (1.1.0-RC3 - 01 December 2015). One decision that I made (and the source of my problems), is to keep the Z home switch separate from the Z probe used for ABL.
You may not realize this... But the RCBugFix branch is always better than the RC branch... The RC branch is frozen and RCBugFix is the RC branch with bug fixes applied to it.
You would be much better off using RCBugFix !
