ABS pump runs after engine is cut off. Battery runs down overnight. I was disconnecting the battery, but then just pulled the fuse.

ABS light comes on and stays on. When you turn off vehicle, there is something still running (ABS Pump); his has occurred three times on my same 2002 GMC Yukon XL (2wd). First time was at 88,500 miles (Dec-2007); 2nd time was 124,498 miles (Jun-2010); and now a third time 160,000 miles (Sep-2014). Something is not right for this to keep re-occurring.
