ABS MODULATOR FIX (NO more SVS fault)

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?

Like i said in the write-up. You must KNOW what error codes you have before doing this repair. If that hole on the fender is not a good ground then of course you will have the lights. that is why i used the bolt.

Hi Josh,
I completed my repair, using your last method that only involves removing the switch. I did find it extremely hard to turn those 3 small Allen screws, they must be installed with Loctite!
I found I had to lift the ABS unit higher to get my old stubby fingers underneath so I wedged a piece of a 2 x 4 under it. I also found those screws so hard to turn with a short Allen wrench that I ended up making up a small Allen wrench socket by sawing off a bit of the wrench and sticking it into a 4mm socket (I used a bit of making tape to make it fit snugly). Before reassembling I took the 3 screws over to my bench top grinder which is also fitted with a fine wire brush and cleaned the threads of any Loctite residue which made screwing them in easier.
I also decided to reinsert the plastic connector plug that I had cut the wires from before replacing the switch assembly as I saw it had an o-ring. I figured it might be good to keep the inside of the ABS unit free from any moisture buildup.
No lights on yet so I will just have to drive it for a while and wait and see if this fixed it!

Im glad it worked out for you! That was a good idea re inserting the connector.

Reistance question
I am in the process of completing this mod to the ABS system to try to banish the amigos. I have completed all steps and am checking conitinuity per step 40. I am getting readings of 3.02, 2.02 and 1.02 KOhms. I assume this is within tolerance but just wanted to make sure I don't need to replace the switches. Thanks again for the great write up!

By the way, I did it 3 times. What have I done wrong? Also I have performed Josh's re-wiring a month ago. Is there anything I can check to make sure the rewiring was completed correctly? I shouldn't get "Shuttle Valve Electric Failure" if it is successful, correct?
Thanks in advance.

Three Amigos Gone!
I took the gamble on option C that Josh posted and the amigos are gone. Indie shop wanted $900 for the fix. Parts and tools cost me $80. So if I split the difference with you Josh then I owe you about $400 bucks.
Like other posts, I also found the hex screws very difficult to remove and suggest to anyone else that tries this to invest the extra $5 bucks in the correct size socket set connection for the 3 hex screws underneath.
Someone really needs to make this the first option that comes up under searching for "Three Amigos". Thanks so much!

Very impressive Josh! Your step by step explanation as well as your excellent photo images are first class. I think I will be attempting this repair in the near future.
Do I need any special tool to reset the system to clear the history of any faults or does it just reset itself?

Chris...I'm in Houston. Can you shoot me an email w/ contact info: lp@wecravesushi.com
I think I have the 3 amigos...
