ABS Modulator and Front Driver side ABS sensor

What do you mean your pads were causing the 2 amigos to light up? I just had my brakes done recently by a very reputeable LR mechanic that has been working on LR's for many years. We ended up doing a modulator rebuild with sensors etc. awhile ago. I had the brakes done a few weeks ago and when I SLOWLY drove over a speed bump the day after, the lights came on again!! I've considered getting rid of my DII because I'm tired of all the ABS problems and cost associated with it regardless of how much I love LR.:banghead:
I had some similar symptoms. At times when I would hit a bump the lights would come on. Then one day they stayed on. I had a tech read the SLABS error codes and it showed a bad left front sensor and shuttle valve problem. (ABS and Traction control stopped working.) So I bought these to replace them.
I put it off because I needed to get my brakes done so I thought I would do it all at once. I did some research on here and I read that many people had problems with using pads other than OEM pads so I thought I'll go back and put on OEM pads. (I had EBC Green pads on there) I put on new rotors (EBC) and pads (OEM). My mechanic reset my ABS lights and my ABS and Traction Control started working and not more lights and no more errors. It has been working for about a month and a half now and no more 3 amigos. Do you have new pads and are your rotors fairly new?

ladies, threads like this make me wonder why you own a disco? if you have ABS problems on your d2, you are either
1-using the wrong parts/experimenting with parts combos(my Ebc pads were way too dusty for a truck this heavy and faded on me)
2-needing to change parts like modulators etc
3-needing to change wiring overlays/sensors
4-needing to get diagnosis from someone who knows what they are doing with a d2, not just any 2 bit brake shop offering the $99 special, or get an abs amigo for the shade tree guys..
do some searches on brake pads for a d2 on this forum, its been said a thousand times, and the 'how to' has been posted as many, its pretty easy to do yourself.
If you cant do brakes, and cant or dont or wont learn how to, discovery ownership could be painful, expensive or both, go buy a jeep and it will cost less to have someone work on it etc
the d2's abs senors register both faults and noise, excessive noise can lead to a fault, using anything but LR Genuine and or Akebono pads for me is a no-no, similarly, I urge you to use only a LR genuine or a DBA rotor,
also, before I retained my rear springs and replaced the stock hardware with grade 8 bolts that were longer and went all the way thru, I didnt have the coils 'seated' fimly and the 'twang' from flex would set of my amigos
again, 'pop' noise induced faults are common to me, mine self reset when its those, nothing to worry about there
thats my 2 cents, I know there are other items folks use with success too,
there are others who live with their three amigos, but really, ya dont have to, its a system that likely worked for a long while before it failed, and if restored correctly can work again
its just not cheap to fix, or easy if youre gonna do it without reading every single post on Dweb that has the words d2 and brake or discovery+brake
I've got 70k + miles of some pretty fun wheeling in some pretty tuff terrain amigo free for the most part once I nailed down my issues. I confess to having had to take it to the dealer for diagnosis too, on occasion, but most fixes are either 'cheap' or can be done at home short of needing a new nod unit. Flush regulalry and use teh right fluids.
YMMV good luck ladies

What year DII? My recurring amigos were corrected with a new SLABS computer (2000 DII). As Gem said someone that really knows these trucks is who you want trouble shooting as with mine the T-4 was saying another sensor. Cory aka OFFROVER checked the serial number on my SLABS and said we needed to change it and that would take care of the problem. It did without changing the harness that the T-4 was saying was wrong. Experience and knowledge goes a long way.

the abs amigo will not tell you if the slabs is bad. no faults and 3 amigos probably means the slabs is bad.. and, I had to replace my slabs, even though it was the upgraded version. I did the 03-04 and it is tons better than the 99-02 as far as abs intrusiveness and traction control quickness.
I think it is funny how gmookher replies to a thread like this in order to inflate hir EGO.
Having owned 3 Discovery's, 1 DI (97) and 2 DII (01 & 03) All my trucks get wheeled. including my MKIII. I have also done brake work on all of them myself. I don't do it now just because I would rather spend time with my Wife and Son then spend the time working on the truck. My wife always helped me work on the Disco's as well.
My play truck (97') has 4:10, ARB front and rear. Great Basin Axles, Warn winch and over 180k miles on it. When my son is old enough to help we will be out there wrenching together but for now I would rather spend a free hour or two with my son vs. a hour or two working on the Disco's. The cost for the labor to be done on the brakes is nothing compared to quality time with my son.
Jeep? Are you kidding me? My father in law has more problems with his jeeps then I ever have had with my Land Rovers and he has had 5 of them.
(I also use a highly recommended independent LR shop that is referenced on this forum)
I was just posting a rely to the question that was asked.
It is a sissy reply like gmookher that really show how ignorant and idiotic people can be.
Yes I could have just posted "do a search". But I thought I would be kind enough to answer the question asked with my experience.

it is actually good info. comparing your built D1 to a D2 is kinda pointless. the only thing that is in common is the rear tail door skin.... (and a few other little things here and there, but it is a totally different truck)

I agree with most of what you've written, but I feel that I need to chime in regarding the need to use OEM brake pads and rotors. In my opinion, this is far from true. I've had 3 different D2s (1999, 2002, and 2004) and I have never had an issue with 3 amigos. I haven't had them on my dashboard for a single day in well over 150k miles of driving. I have had them make a guest appearance while driving off-road because of noise, as you describe, but a simple restart clears them. This has happened fewer times than I can count on one hand in the last 10 years. I realize that this may be a rare occurrence, but I don't think it's a huge coincidence.
Any time I buy a used vehicle, I replace the brake pads and rotors immediately. In my opinion, it's just a safety precaution and a good investment. Who knows what sort of cheap junk the last 'mechanic' used? I always use aftermarket slotted rotors (from various sources) and aftermarket pads from a reputable manufacturer. (NOT EBC crap) I typically use Mintex or Ferodo, sometimes even Raybestos. I change my oil every 3k miles. Every time I change the oil, I rotate the tires. Every time I rotate the the tires I inspect the brakes. If the brake pads are below 50% remaining, I order new parts and change them with the next inspection. If the rotors have any sign of a ridge, I turn them and make sure they're still within spec. Brake fluid gets changed every 30k miles.
Sure, I believe that the modulators are a weak link from the factory, but I think that a lack of maintenance is what causes most '3 amigos' situations.
Again, I'm no expert. This is just my opinion and experience.
