Thread: On going 3 amigos and fault definition

yep, done the option b on 2 D2's now, no issues with abs since
also, see hummer abs faults, same modulator, same faults.
they use lr units in place of original hummer.

Thanks for the info everyone and the offer Andrew. Hope you all had a great Christmas. This All depends on what the wife thinks, the problem is on her vehicle and not mine, we both drive D2'a hers is 2003, and mine 1999. I've also just found out from Austral LR the wifes car had a LR recall for an ABS problem relating to ABS electrical components cracking and causing dramas. Could not tell me much more but sounds like the same thing.

The recall was to replace the top "caps" on top of the valves on the ABS modulator. The shuttle valve issue has never been a recall, although it blooming well should have been!!!

I was reading the link to the hummer wabco rebuild and it notes a difference between some of the later D2 ABS blocks. Where the caps are different thicknesses. It seemed to be a across the board thing where (it's seemed to be US D2a's) the caps were made thicker but the pics as I saw it described were two pieces.

After living with the 3 for the past few years and constantly having to reset them, i finally got around to doing option B yesterday. A couple of hours later and i am glad to say they are gone ! All the TC, HDC and ABS work as they should and this is with Bendix pads on OEM rotors. $15 for the the lead and plug plus some patience is all it cost me. BRILLIANT !!

P.S. I was quoted up to 1200 for the modulator repairkit installed from an expert.

Thanks for the advice

George.

Great news...love it when a plan comes together.

I did option B recently when the 3 's came on.
There were two codes that came up, one for the shuttle valves and one for the RHF wheel sensor. Did the shuttle valve wiring mod to the modulator and fitted a new wheel sensor, got the codes cleared, and its all fixed. Coupla bucks for the wiring, $150 for the sensor.
I understand the different ways we all approach repairing things. Some of us have the time and ability to do it ourselves, some of us need to take it in to get things like this fixed. I'm an ex-mechanic with heaps of ABS, EFI and auto trans experience so it was easy to have a go for me. I did get quoted $800 to reco the modulator which is probably reasonable if they want to cover all possibilities (not sure if they do anything like option B in the process). I've noticed that indi LR repairers here in SA tend to recommend going the whole way with repairs (eg fitting a whole front hub) rather than trial and error (replacing a wheel sensor first), but are happy to give advice once you get to know them (and buy parts off them!).

sorry for my ignorance and I have tried very hard to find the answer by searching but no joy


what exactly is "option b" please


thanks in advance
