I shouldn't have used the word ABS, it could be the ABS DSC, DTC or whatever the marketing team calls the software in the car in this particular moment in time. Bottom line is that since you said the suspension assembly on that wheel was recently touched, chances are, it's either a mechanical issue with the brakes, which based on description doesn't sound like it (it's too "digital" in nature), or some electronic sensor in the area. The Pulse Generator is very likely. It might either be faulty or mis-mounted or badly plugged in.
"Once these lights are on i can drive and brake with no problem." - this statement is a DEAD giveaway that the problem is digital in nature. When the car detects an inconsistent reading from one of its sensors it disables all assist functions. So if the system detected a pulse from 3 wheels but no pulse from one of the wheels it knows something is wrong and it can no longer rely on those inputs to make decisions. The brakes grabbing is likely a DSC response and not ABS, but that's irrelevant.
