All 3 of these lights came on today as I was driving and stayed on until I turned the vehicle off. now they aren't on. Has anyone else had this problem?

Get your fault codes checked. I bent over and paid for the modulator rebuild and have had no further problems. Runs about $900.

I wasted time and money with shuttle valve replacements, installing used modulators etc.

This is a well discussed subject on this board. Do a search but my suggestion is what I stated above.

Good luck!

before you go crazy thinking this a major problem, this could be as simple as a intermittent senor.

X2! You experienced a "soft" fault. Had it been a hard fault you would still have the lights and need testbook, rovacomm, etc to read the SLABS and confirm what the problem is (most likely a sensor). If you are unfamiliar with this system go up and search three amigos and read up. In short the stock modulators on these things are sensitive. Land Rover now has modulators in supply that are less sensitive as well as new one piece overlay harnesses for the sensors. FWIW I have had my truck for four years and have beat/wheeled the shit out of it. I have only had to replace two sensors and each time the problem went away totally, no intermittent three amigos. So when reading all this gloom and doom about DII ABS/TC/HDC shit take it with a grain of salt. They're not all bad.

Cheers,

Mike

X2 , my indy tech insists the modulators made now are much better... his comment was, once they are replaced with the new design, they never come back..

I did mine about 6 months ago with a new unit...

The newer sensors are much, much better. From what I understand they are a one piece unit, rather than the old individual, pluggable components. Basically, less joins = less points of failure.
I've had all my ABS sensors replaced and haven't had a single problem since.

Relax and just learn to say "buenos dias amigos" when they come on (unless it's after lunch then say "buenos tardes") ... and remember to pump instead of mash.

My amigos show up from time to time. Sometimes they are off when I turn the car off. Then on when I start it up. I'm not to worried until they don't go away period.
I went out for Mexican tonight and they went away after we left the restauraunt.
Muchos Gracias
