ABS MODULATOR FIX (NO more SVS fault)
Have had them go on and off intermittently for last 2 months, and my reader always had shuttle valve code. So after reading thru the whole procedure, I spliced into the yellow/green wire and into the ground wire that plugs into the abs, below the bigger plug, I have some lockitt pos-taps that i had purchased previously, pricey but makes splicing a breeze. This was to get ready for the new wires. The three hex bolts were tight but manageable. This was the original shuttle valve, and showed no signs of brake fluid, but the insulation on the wires were brittle, so I carefully stripped and soldered the wires to run and shrink wrapped it all. It went back on easily and took no time to button up. Started up and no amigos. Hasta La Vista Amigos.

Hi
I have downloaded the 56 page pdf and studied it thoroughly. The thing is, all I get is the ABS light come on randomly, even when not touching the brakes, and it goes out if I restart the engine.
So does this merit the work in the pdf or is this merely a poor connection fooling the ECU to report a fault.
Thanks
Geoff

Do you have a code reader that reads the codes? If you can get it read and it says anything about shuttle valve, Do the option B mod, and forget about it. Mine would come on randomly and i could restart and it would be off. The mod does not take long and I have not had a light since the day i did it.
Yes it did report that... I was just being ultra optimistic that, because it reported so seldom and I didn't get the amigoes, it might have been something simpler.
Anyway, I will look into plan B next weekend.
Thanks

edit: most of the original info is gone, but a couple of guys put up some decent info.
figured it would be helpful to put the good stuff together and not have to look through the dead links. the below link will get you there and if anyone has any additional info, please share....,dusty

Well everyone, here is MY ABS Modulator fix write up.
Let me know what you all think....

Well it would be good to clean this thread up. 22 pages, and a lot of not.
I will add that to my to do list.
I maybe remembering a different thread entirely, but a couple of guys had saved this info and shared it. Thought they put it back on this thread, but they could have put it in another.

Well Option B worked for me. I have about 1000 miles on it with no Amigos after doing the mod and a proper bleed of the entire brake system. Bleeding the system good is very important. Don't just bleed the modulator, do all 4 calipers too.
I wouldn't use the "quad rings" provided in the Falconworks kit. They made the actual shuttle valves very sticky. I didn't have any leaks, so I just used the o rings.

Thanks Josh. As you suggested I will continue my questions here.
I don't have any testing tool at all. The 3 amigos was there for like 3 months, not an intermittent one. A friend of mine used his OBDII to test my truck and gave him something "Shuttle Valve Failure" blah blah. I tried the troubleshooting manual/pdf in your website and no luck. That's why I want to give a try to the bypass option B. I went thru all the steps, and the connection testing at Step 40 is also fine. But when I re-installed everything, turned the key, too bad the lights were still there.
The only difference between my work and yours is, I think, I ground the harness to the hole I indicated in the pic rather than the bolt holding the pipe like you. Is that possible it is the reason?

Nanocom codes I've found
Hello there.
Wonder if you can have a look and maybe could recognise below, please?
I have 3amigos visiting randomly, sometimes just abs+tc light.
When turning ignition key ACE light is illuminating. However if turn the key quick enough then no ACE on dash.
codes are:
(16,2) high speed crank (logged).
(22,1) road speed missing,(logged).
23-15 shuttle valve switch electrical fail - intermittent 123 times
fault 01-05 upper and lower accelerometer signal too different
Any advice where to start?
I've checked the wheel hubs and no play detected.
I'm going to do the B option modulator mod.
Should I replace the abs sensor wires and solder them?
Regards
