Mine have been clearing themselves. When I started up I had no codes.

With shuttle valve switch ground faults = the 3 Amigo’s will come & go with a key cycle.

Mine would not always clear with a key cycle. Occasionally they’d be there after a key cycle, sometimes for an entire day, but then they would disappear for days on end. This could point to wheel sensor wiring problems but I’ve gone well beyond the typical appearance in mileage this week and have not seen the amigos since the Option B procedure. I didn’t have any stored codes either and thanks to some sporty weather in the Phila area this week I had plenty of opportunities to ensure my ABS is functioning.

mln01, I went back and corrected my my post to clear up the reference to shuttle valves and clarify that it was only the switches I was dealing with. That said, as I understand it Option B is only about correcting the wiring to/from the switches and nothing to do with the actual valves.

Almost two weeks in and about 500 miles with no occurrence of the three amigos. One side effect I have noticed is that prior to doing Option B the ABS light was one of the last lights to extinguish when starting the truck, the SRS being the only one after that. I would always watch to see if TC and HDC joined it. After doing Option B the ABS light is one of the first lights to extinguish at startup. This could be helpful in determining if the problem is the shuttle valve switches or a wheel sensor.
