2004 Land Rover Discovery II - Traction Control/ABS Issue

[amarkley]

Hello all,



I have a 2004 Land Rover Discovery II that has 150,000 miles. For the past few weeks, I have had the famous “Three Amigos” lights on. I read the ABS codes and found that the ABS system was throwing “Right Rear ABS Sensor Signal Erratic.” For context, I had a dog that chewed through the right rear ABS sensor cable, but I had it repaired (not replaced). The repair held for a while, but alas my “Three Amigos” came on again. Anyways, I replaced the rear right ABS sensor, cleared the engine and ABS codes, and now I have a completely different issue which is the subject of this forum post. The next day after replacing the ABS sensor I noticed that the traction control light comes on when accelerating over any bump in the road. Keep in mind that the “Three Amigos” are now gone along with every other engine light. The traction control light is also accompanied by the front left wheel breaking hard (basically, TC is on only for the front left wheel). Naturally, I read the ABS codes again and found that I am getting two codes: “Pump failure 2 (pump not running when actuated)” + “Pump failure 3 (pump sticking).” I did some digging on every Land Rover forum I know of and found that the R10 relay could potentially be the issue for Pump failure 3, so I tried swapping the R10 relay with the Auxiliary Circuits relay, but to no avail. Since the same issue was present when swapping the relays (and no other issues appeared), I am assuming that both relays are good. At this point I have not found a solution to any of the faults. Any help would be greatly appreciated.

I used a rubber mallet to securely connect the sensor to the wheel hub and it fixed the problem! Those sensors are stubborn sometimes!

I have the same truck -- same year same mileage. I tried a number of known options -- all of them -- to fix the 3 amigos. I spent a long time working this out, I've had the truck for many years now. The *only* fix that worked was the solution provided by ebayer username 'gemma400ci' he's in the UK ... going on two years and ABS/TC/HD lights -- the dreaded 3 amigos -- are permanently gone, a thing of the past. He provides basic directions w the kit, if you've dealt w the issue, it'll make sense. Nothing really worked w/ the standard procedures / write-ups. It's not difficult at all to implement if you're the least bit handy... I used a 2x4 lever plus ratchet strap contraption to hold the ABS module up away from the wheel well while I accessed the allenhead bolts from the underneath w a mirror. Peace.
