Well I hate people getting discouraged and getting rid of a classic car all due to little nuances like the 3 amigos. Plus it's because of the forum(s) that I have been able to make a little something on the weekends fixing rovers. It's just fair to give back.

That and I don't want to see this question asked ever again.. lol j/k...

I appreciate that!

People should have to spend a week on this forum prior to buying a DII.

UPDATED TO INCLUDE STRAIGHT WIRING OF THE SVS.... AND REMOVING THE MODULATOR SIDE OF THE PUMP ONLY...

Sorry its all on one page but I feel that anyone performing this job should read through all 50 steps first....

Hi Josh,

It is a really helpful instruction, and I used Option B to diagnose the 3 Amigos. However, SVS valves are working fine, the voltages were as you had shown in the instruction, the connector is good as well.

The connnection inside ABS module to outside connector is also good. I can't figure out why my 3 Amigos lights are ON. Any idea what would be other causes?

Do we need special Amigo Scanner to clear the code or ordinary OBDII scanner such as Innova or Actron would do the job? Thanks.

Thanks...

The resistance test in the write up is only to test the Shuttle Valve switches. It will not tell you why your amigos is on. My switches were good but i still had the amigos. You need to get the codes read before doing anything. I specifically addressed that in the write-up.

You can buy the ABS Amigo.... or go find a shop near you that has a capable scanner. In the states you are limited to the hawkeye scanner and the ABS amigo before you start buying REALLY expensive rover capable scanners.

Now that you verified that your SVS are good, you can ASSUME it is the electrical fault mentioned in the write-up if the amigos go away after you restart the engine.

GET THE CODES READ..get back to us with all the codes. Don't do anything else until then.

Josh,
Thanks for the write up! I did the "option B" fix on my '00 D2, and for the first time in years, my thee-amigos lights are off. Much better!

One thing to possibly add to your write up: After I got my modulator assembly all back together, I realized it would have been better to re-insert the cut-off SVS plug into the modulator body, just to keep a good watertight seal for the internal electronics.

Glad it worked out for you. Did you scan the codes and confirm that was the problem? You should add the following to your signature.

"Amigos Free since 12/2009"

RE: ABD Modulator FIX-3 Amigos Symptoms?

I also have the intermittent 3 Amigos on my 03 disco as well. Can everyone please confirm that when their 3 amigos are lit up on the dash board you have no ABS and TC? My truck has no ABS or TC when the lights are on. Had the family in the truck yesterday during a snow storm and almost crashed the truck when the amigos came on while going down an icy hill-Very scary with no ABS/TC.
Thanks, Chris

I want to be Amigo Free!

I only have two of the three amigos (TC & DH) lit with the ABS randomly showing up. I feel comfortable working on most D2 projects, and this one looks easy enough, but then again i've said that before and been very wrong.

Anyway I just wanted to see if there is anybody out there looking to make some extra cash for the project. I live around West Chester PA so shoot me a response back if you can do the work.

I have TC and DH all the time with their brother ABS chiming in about 10-15 minutes into the trip. Funny thing is I almost never had these lights before my motor was rebuilt, anyway I bought the abs amigo last week awaiting its arrival with anticipation so I can clear these codes and tell you guys which ones I've got, if it lines up then I'll perform fix B...

Got my ABS Amigo in the mail today - here are the codes...am I a candidate for the ABS modulator fix?
1.--Current Faults---->
Active Faults:
None
Logged Faults:
021:Engine PWM signal bad
114:Shuttle Valve Electric Failure
<-END Faults
------------------------------------------------------------

067:Rear Right sensor electric fail

<-END Faults


After clearing them out I started her up, within about 20 seconds the TC and HDC lights came back on, here are the codes.

Just did the fix using the hard wiring and it was pretty easy. The three hex screws are the only problem. Other than that it was easy. It takes about an hour as long as you pre-wire the connectors.

Not sure if this fix will fix your problem but I'm in Syracuse if you can't find anyone closer. Might even be able to do it in Binghamton.

Hi,

I already had my mechanic replace the shuttle valve, but that didn't work, so I just bought an ABS Amigo and got the following:
1.--Current Faults---->
Active Faults:
114:Shuttle Valve Electric Failure
Logged Faults:
114:Shuttle Valve Electric Failure
<-END Faults

Before I attempt it, my mechanically inept-self, just wanted to verify that Option B should take care of this? Also, before even doing that should I try the troubleshooting in the Technical Bulletins on the ABS Amigo site?

Thanks!

Steven

This looks like a very well thought out and performed fix that I should be able to do. I've had the 3 amigos for a few months so today I'm gonna try to get rid of the lil SOBs. I really appreciate the step by step instructions with detailed pics. Now I've got to check on why my blinkers aren't working for similar instructions and I'm off to try this out. I'll check back in and let everyone know how it go.
