Quick question I get the 3 amigos a few times a week, not too often but still get them. Tonight I hooked up my diagnostic tool and was doing some adaptations and when i was running LIVE DATA tests and came to the shuttle valve it kept going OFF OPEN CIRCUIT OFF OPEN CIRCUIT over and over. Is this an indication that there I should pick up a new shuttle valve for the 80-100usd and just replace it?

Thanks

i would suggest looking up option b to fix the shuttle valve instead of buying one

 

Ditto.

A shuttle valve fault code can be caused by a failed shuttle valve, but it seems that more often it's caused by a solder joint or joints failing on a small circuit board buried inside the modulator. Option B bypasses the failed solder joint and restores full ABS, traction control and hill descent control function.

So yes, search for Option B. It takes maybe an hour (some of it tedious), a $4 part, a little solder and a soldering gun and some heat-shrink tubing. I did it years ago. See my signature below.

Odds are that if you buy a new shuttle valve and replace it you'll still have the Three Amigos.

Good luck, and let us know how it works out for you.

 

I was thinking for 90 bucks why not just replace it but if you think the theee amigos will still show up cause regardless of new or old the connection is just crap I'll go for the bypass.

Thanks for the suggestion guys

thanks

for me it was less about the money verses knowing that the part will fail again and i can make a stronger more reliable connection
