I've had this problem many times. it appears to be fixed currently by the simple process of using compressed air to blow the dust out of the backs of the wheels. It can't be just a co-incidence...I hope!! At least it costs nothing to try it.

What condition are your brake pads and has anyone done what mumbo has done, has anyone cleaned anything (ie) the connections of the ABS sensors or around the hubs.
Worn brake pads can contribute to the 3 amigoes, as can dirt, dust, mud, squealing pads and so on.
Before you go spending hundreds of dollars, clean all these things first, then have the faults cleared, if they keep doing it, then look at the modulator or a replacing a wheel sensor.

Do a search on this forum for a post by Stevo, where he covers the shuttle valve and a bit more.
I had an issue - bought the shuttle valve kit from British 4wd ($120.00) changed over the switch - ???? old switch still okay......???
So I followed Stevo's to inspect the section where the shuttle valve plugs in, I didn't have the same issue, but the four terminals (two each side) we a little dirty. Cleaned them up, put it all together, got the fault cleared and they have not re-appeared (the three amigo's)
Plus I did the work with the modulator still in the vehicle, which meant I did not have to disconnect any brake likes or have the system bled afterwards.
We had a bit of a trip this w/end to mount terrible, up some mild rough stuff, tested out the hill decent, all working and still no light. So I am fairly convinced this was a fix.
All in all, I guess to remove the old shuttle valve switch and replace it took me less than an hour. Then the second time to remove the switch, remove the side plate and clean all the terminals, and put it together again took just over an hour.
Pads a near new LR - I have learnt enough over the years to know that whilst the Jury might be out on whether aftermarket pads to cause harmonic vibrations etc enough to set off the sensors, its just safer to pay a bit more and stick with originals.

It’s no wonder that it’s highly recommended to pressure bleed the system from the master

I have had an air pocket behind one of the actuators before, the pedal is nearly impossible to
push, but the brakes do work! The fix, well I removed it to have it rebuilt, and lo and behold, I
find out they don't touch that when rebuilding. So simply removing the unit and letting all the
air back in was enough to reset the actuator. Reinstalled and it was good to go.
I have put some miles (and some bumps and bounces) on it now, enough for the code to
come back if it was going to………………and no codes!

So what does this mean for ozscott and any others who suffer same problem (myself included) - remove the unit - let air in and away you go???
Had new abs sensor installed to LF 2 weeks ago - all fine for a week or 2. Braked heavily over a rut - on come 3 amigos. Go home in disgust. Next time back in car 3 amigos gone. 5 days later just driving - notice slight squeal in disc as driving - next thing without braking on come 3 amigos.... got to destination - turned off - next time car turned on 3 amigos gone. I presume that if this happens 3 times then next time 3 amigos then turning car on/off will not clear.???
I understand the early model D2's has a problem with the wheel sensors vibrating out of their housing. This causes an excess gap which triggers a fault. This was rectified with a new fitment method in later models. I think the later ones are a screw fit as opposed to a press fit.
Hi Ozscott,
I have a 2000 TD5 & had a few 3 Amigo issues even under warranty.
The first time the computer said it was front right sensor. LR replaced sensor twice, but lights on again two weeks later & second time one month . Finally traced to intermittent wiring harness. LR ran some external cabling to sensor socket.
Next well out of warranty, 3 Amigos again! Computer diagnosed ABS modulator- shuttle valve. LR wanted to charge me for new modulator ($3500) but i did some searching on LR forums & found out there was a cheap kit to fix modulator. Told LR about kit & they agreed to obtain & fit. Only $500 inc labour.
Touch wood, I have not had any ABS/traction problems since.
Cheers..B
Thanks all. I just spent 4 days traversing Fraser Island. They have not had rain for a long time and the tracks were very very soft and boggy - more people were getting stuck at Indian Head than made it through...of course the Disco in third low and my 265/70/16 at 20 pounds went straight past an 80 series that was bogged trying to get past a 100 series bogged....and I had to go into the softest part to do it. My mate with the same set up followed me not problems in the world....love it...(both manual V8's) on the way back waited in the thick stuff for the GU Patrol to be snatched out and idled through....traction control got a great workout and never missed a beat.
Cheers
PS. No error lights at all for some reason all trip
My 2002 TD5 has intermittent 3 amigos, they come on when driving along even without bumps or braking. The Nanocom shows an intermittent shuttle valve fault (up to 254 times), no sensor faults since I cleaned all the connectors. The lights clear after turning off the ignition, sometimes I will go a week or so without the lights, sometimes I see them a few times in a day but they always clear (at least for a short while) when the ignition is switched off and back on.
My vehicle had a shuttle valve kit fitted about a year ago (before I bought it). I haven't used hill descent or had TC come on recently. Might take it out to Yalwal soon for a workout and see if the three amigos go on holiday.
Regards
Hi Scott.
The beauty of a rover diff:cool::cool::cool::cool:
Those nissans and tojos have a substantialy bigger sized diff than yours that works just like an anchor in the sand.
Great to see the D2 excelled itself for you in the sand.
ENJOY
Andrew
