Land Rover Repair: ABS/TC/HDC - The 3 Amigos, john mcinnis, speed sensor

Question
Hi John, I note that John McInnis is on vacation so wondered if you could help with what appears to be a common problem on Disco 2's. I have had mine for 2 years now and just gone over 53k Miles - At the start of a recent visit to France the 3 Amigo's appeared! and are still with me despite doing all the recommended fuse pulling, battery disconnect etc.
Question, is there a recognised route to getting this sorted or I am in the laps of dealers dabbling at my expense until it is fixed.
regards

Answer
The most common cause of these lights coming on together is a fault at one of the hubs.  The problem could be within the hub or the speed sensor, which is sold as part of the hub or separately.

You'll need a shop with the specialist LR test system to diagnose this.
