Any ABS trouble codes setting and is a scan tool available to monitor wheel speed sensors to see if the right rear wheel may be dropping out at slower speeds causing the lockup? Is there a leak in the right rear from brake fluid like a wheel cylinder?

Are you able to monitor the wheel speeds on a scan tool and see if the rear wheel "drops off" say under 10 mph or so? This is what usually happens when the ABS is setting and the wheel locks up because the ABS is confused and not too sure if it should let it rotate or lock it up.
