Yet another 3 amigos question
I recently got a Hawkeye diagnostic tool, which I'm hoping will be helpful with ABS-related stuff and brake bleeding, among other things. I hooked it up and read ABS codes, and it turned up "fault 4114 historical shuttle valve switch failure."
From what I can tell this is likely the classic 3 amigos issue. Do others concur? It seems I have a couple options: do an electrical hack or buy a new shuttle valve assembly for around $80 and hope it's not some other issue with the brake/wheel speed sensors. A couple questions for those in the know:
1) Are there additional steps I should take to isolate this as a shuttle valve issue, or does this fault code itself confirm that the fix is to replace/hack the valve?
2) Taking cost out of the equation for the moment, how would you compare option B here (ABS Mod - LAND ROVER CLUB V.I.) with replacing the shuttle assembly? Is replacing the assembly a less-permanent fix than option B?
Thanks, and sorry to dredge up something that's been covered so heavily already.

The Option B bypass and shuttle valve replacement address two different problems, either of which will trigger the code you report.
In my case I inspected and tested the switches per the Option B procedure. There was no brake fluid evident on them and electrical resistance passed the tests.
Some recommend going ahead and replacing the switches regardless but I'm something of a tightwad so I took the risk that the switches would fail later and I would have to spend and hour and a hundred bucks later to replace them. So far so good - five and a half years later.

Ah, ok, I think I get it. So if I go through the testing procedures on the Option B website and the shuttle valve doesn't pass, then I definitely need a new shuttle valve. If it does pass, then I know it's not the shuttle valve and Option B will solve it. I could optionally replace the shuttle valve while I'm there AND do Option B, but that costs more money.
That about right?
