Thread: 3 Amigos - Symptoms and Remedy

Someone we all know well will point you to "The Good Oil" very soon, but until Pedro does, this is what I have plagiarised from the internet and AULRO.

oops, file is too big. dont waste your time opening it.

Best thing is to have a read here http://www.robisonservice.com/articles/RonR_aug2006.asp

And if all else fails, option B.

Yes, option B fixes one of the (major) issues up - but how do you know to do an option B, or some other part of the system is causing the fault?

That's what I'd like to compile. The article indicated indicates that a lot of the time it's a wheel sensor, sometimes it's a connector, or an earthing problem or or or...

Any takers to add to / correct the list below or is this too hard to do, given the variety of issues? ? If there is a lot of replies, I'll put the results into a table to assist in readability. The list would only be a guide to what solutions are available to get people started in the right direction.

For example ( I don't know if some of these are valid items that aulro people have seen) just examples that I have read about (or I envisaged)

Sensor issues
Indicator/s - Lots of brake dust on the rims and most probably on the sensors.
Fault isolation
Try using a high water pressure clean between disc and disc cover to remove dust on ABS stator and wheel sensor. If this fails, then wheel and disc off?
Possible solution/s
Different brake pads

Sensor issues
Indicator/s - 3 amigos after mud run

Fault isolation
Try using a high water pressure clean between disc and disc cover to remove mud on ABS stator and wheel sensor. If this fails, then wheel and disc off to get to mud build up?

Possible solution/s
None - mud is a part of owning a 4WD.

Indicator/s Obvious grease build up on ? (don't know if there are any indicators?) -
Fault isolation
wheel and disc off and clean grease around sensor and interruptor.
Possible solution/s
Fix grease leak

Indicator/s
Brake fluid under ABS? - switch failure?

Fault isolation
Inspect and replace shuttle seals (and shuttle valve switch if readings aren't within range)

Possible solution/s
Replace modulator switch
Replace modulator

Indicator/s
Brake squeal, immediately followed by 3 amigos

Fault isolation
Check discs for wear and glaze
Replace brake pad/s and discs?

Possible Solutions
Replace brake pad/s and discs?

There are also the indicators, fault isolation in LTB00060.

The sensors are inside the hubs and are sealed so pressure wash won't make any difference other than remove brake dust from the calipers.

Your best bet is to remove the modulator as I am about to do and at least check it you need to do option B.
Falconworks in the US do a modulator kit AND upgraded seal kit for US$130.00.

Might even sus out the rocker grease too.

For the tutorial, this is the most popular if not the best stage by stage one I have come across although I have a repair for the board problem that is similar to option C but maintains the plug.

hi all , since i upgraded the suspension i have not had a visit from our three fiends maybe it was the ABS extensions that fixed it i dont know but they've been gone a while now.tony

There are a few suggestions out there that are simply false which have resulted in a resolution for the owner by default (dumb luck) rather than correct diagnosis.

But as already mentioned "The Good Oil" has everything to diagnose and fix the Amigoes.
The info you seek to compile is commendable but exists already.
I think Pedro has already got most of it organised quite comprehensively.
However if you think you can compile a more user friendly flow chart you will likely make Pedro very happy.

I have had several run ins - the nanocom indicates a switch problem, but it comes and goes and doesn't get any worse. I've driven thousands without having any problems, then they visit for a month!!

Here is a classic example.
No offence meant to anyone.....Its easier to clear the fault than it is to diagnose it. I know for fact this could be sorted within 2 hours and the fault rectified.

I have personally posted the checks and solution options to this exact fault at least twice along with dozens of members.
Posted also is that diagnostic tools do not assure the user of directly finding the faulty component and sometimes point to the component associated with the fault, requiring some knowledge and understanding beyond a push of a button.

Many forum members have also posted similar to this.
.........if you dont have a workshop manual or dont/cant understand the system and/or info in the "Good Oil", or you dont have the confidence or tools..... you really shouldnt be messing with it by yourself.

The ongoing 3 amigoes posts are becoming tiresome and prove that people are too lazy to search, or as per paragraph above. Either way....tiresome

cheers

Hi all,
Have been reading forum on ABS issues. My problem is different in that the descent control lt. does not come on but the handbrake lt. does. [along with TC & ABS].Any help is welcome.
Thanks
