Curious three amigos issue
#11
That is my point the TC fires up if I touch the accelerator on a left turn and the light flashes on. Also if I go over a bump in the road. Then it goes off - it could be dangerous if that happens on the highway at 70MPH. I have pulled the ABS fuse temporarily which means the lights are back on and it drives fine - I only fitted the overlay harness to get rid of the damn lights. Seems I have paid for an expensive length of cable and fitting for no benefit.
Could it be a faulty left front speed sensor? No fault codes yet at all.

Per RAVE:
ETC
The ETC function uses brake intervention to prevent wheel spin and maintain even torque distribution to the wheels.
ETC is automatically enabled while the brakes are off at speeds up to 62.5 mph (100 km/h), and operates the brakes
either individually or in axle pairs:

ETC is automatically enabled while the brakes are off at speeds up to 62.5 mph (100 km/h), and operates the brakes
either individually or in axle pairs:
-At speeds up to 31.3 mph (50 km/h), ETC uses individual brake intervention to maintain even torque distribution
between wheels on the same axle.
-Vehicles up to 03 model year – At speeds between 0 and 62.5 mph (0 and 100 km/h), ETC also uses brake
intervention in axle pairs to maintain even torque distribution between the front and rear axles. In effect, this mode
of operation replaces the centre differential lock of the transfer box which, although still incorporated, is non operational under normal driving conditions.

During active braking the SLABS ECU also illuminates the

That cannot be right
Personally having driven extensivley off road in the RMs and in divvy competitions in the 1980's (I have trophies) I have never needed TC or ABS I do not see how it delivers any benefit over knowing how to drive -in most vehicles you can turn it off.

So when I slowly navigate a left hand corner on dry road the brakes are supposed to take over? No this definitely a problem. It does not do it the same on right hand corners. And going over a small bump I get this rettling ABS sound and the traction light flashing? Frightened the heck out of my wife. It could cause loss of control at 70 on the highway. I understand that there was a recall on MY2000 ABS units so I will call the LR Dealer and see if mine missed it.

I recieved my Autel MD802 diagnostic tool today and I am happy to report that it works well. The codes I have are the shuttle valve electrical failure, and RR wheel speed sensor signal eratic and RR WSS electrical failure. I rewired the shuttle valves using option B from the sticky and pulled the wheel speed sensor and cleaned and reseated it and tested for resistence again. Took it for a test drive and engaged TC ABS and HDC and so far so good. We will see. Thank you guys very much for the help!

1 Wheel Drive
Disco Mike,
In a previous post you mentioned that with the 3 amigos on all the time which I have had for about a year now, the only wheel driving is the Left Rear. Is this correct and why? Why/how does the vehicle go from AWD to single wheel drive because of a brake fault?
Thanks for all your help on this forum.

Now it would have been an alternative to fit mechanical limited slip axle diffs or even air lockers but their target audience for new sales are not off road enthusiasts but people who are buying the image. Us used purchasers are the ones who inherit all these unnecessary complicated systems. I am sure there must be a market for a Bare Bones Disco or Landrover at under $30k? Back to the actual concept and not a 4WD pimp mobile.

TC misbehaving further info
Still got the same problem but not as bad.

so I'm replying to myself, but whatever. In response to my question of whether the 2004 Discovery II SE7 defaults to 1 wheel drive (Left Rear wheel) when you get the "3 Amigos", that seems to be false. According to the dealer's lead tech when you lose the ABS you lose the traction control that applies breaking to the wheel that is spinning, and HDC et al, but the truck is full time all wheel drive, even without the ABS. Ours has the locking diff allowing us to go from high FWD to Low FWD but we're allways in FWD unless we unlock the diff and leave it in neutral.
I'll put the thing on jacks this weekend and hit the gas, if I see all four wheels spin then that's that.
So I'm back to wondering why anyone cares if the ABS system goes out. One less system to worry about, just like the secondary air injection system.
