Hi, I recently started working on my wife's 1993 B2200 and reconnected the speed sensor for the RABS (it never was reconnected when the axle was swapped). Now the Anti-Lock is activating every time I bring the truck to a complete stop - sometimes, the piston stays activated even after the truck is stationary and the brakes are applied.

That's not the way the RABS is supposed to function is it? Would you imagine the control unit is faulty now?
