This is doing my head in.

Ok,

What have you replaced?

Many moons ago I believe I posted about the difference in the SLABS ECU in the later revisions.

I can't remember exactly what I said, and I'm typng this off the top of my head, but the early units were something like SRD000070, the later were something like SRD000150.

The later units operate better with a reinstated CDL , but they are also less aggressive when reporting faults, I have changed the ECU to a later one on one of my cars which kept throwing faults, guess what? No more faults.

Yes, I have also seen the 3 amigos but had no fault registered.

I think it was an earthing problem next to the engine bay fuse box.

If you want to upgrade the slabs, let me know and I'll go hunting for the correct version so you don't get the wrong one.

I haven't played with some if this stuff for maybe 5-6 years.

Also I remember a lot of eBay sellers that had the SRD00070 unit trying to sell it as a replacement in the facelift ones, this is not right.

Also in the back of my mind is a TSB to replace certain revision SLABS controllers as they were faulty, but my memory is also faulty... So who knows!

I understand your frustrations....

I've replaced the front left hub. I've also replaced the right rear ABS sensor because, well Nanocom.
The earths idea sounds good. I've looked at Rave and decided to start at the rear, 'cos it is a Land Rover. RAVE states "Refer to Connector Details for locations of earth points and headers." This is under a diagram of where the earth points are. Where is Connector Details? as Connector Views does not match. I'm missing something.
I will give C0362 and C0017 a look at first as they seem to be close the the ECU. Or is that too obvious?
As expected the ABS light sent out at 20kph

As long as the ABS light remained on alone and went out after the vehicle exceeded 15km/h the problem was something about a sensor's signal for sure, for any other issue this ABS light thing doesnt happen the amigos are going out all together, i doubt it has anything to do with earth, IMO your ECU is making tricks which was obvious based on those mixed up readings too.

the early facelifts were fitted with SRD000150 which was the first version of the uprated ECU which can manage the CDL and TC together without disabling the TC with locked diff but these ECUs are too sensitive and are a quite common failure hence they were superseded by the improved SRD500070 which is the best of all.... all the others(SRD100461/100462/000070) were fitted to non-facelifts they disable the TC if the ignition is turned on with locked diff or can mix up the system's behaviour otherwise but are more "robust" when it comes to fault codes

strangely nanocom is not always wrong with the sensor's position but maybe it has to do with the ECU modell too... i'll have to investigate but i'm sure that it reports the sensors correctly on mine

Do you have a date of the change over?

No i dont, AFAIK the 500070 was fitted to late facelifts(2004) then sold as new replacement part for all

Yesterday, the party lights came on again. No fault detected, lights went out when car started. Today, The lights are up again, this time with a fault. The fault was front left sensor electrical failure 018 times. I disconnected the front ABS sensor, got the same faults, the inputs gave 0.00V for the right rear. I plugged the sensor back in and the fault remains. I checked the connector that I had put in and that had failed. I removed the connector and hard wired the cables together. The three amigos left without me needing to reset the fault.
