ABS TC Flicker/pump 3 failure

As per title, when driving I get the TC light flicker now and again, also it will start to push me off the brakes when I’m hard on it way before the wheels lock up, it’s kinda dangerous.

I’ve got a code for pump 3 failure (sticking)

I’ve already done the shuttle valve wiring mod (and tested the switches) and that’s all good.

Is there something simple I need to look at or is it time for a new pump?

It's a disballance between the wheel speed sensor's inputs so the TC and EBD are kicking in when not needed... what diagnostic tool gave you that "pump 3 ..." code? cos it doesnt seem LR specific

It’s not a cheap one but it’s not a landy specific one, it’s a garage type do anything jobby

The ABS sensor inputs must be monitored while driving when the symptom occurs cos one of them is making tricks. Was a hub replaced before this problem?

Have tried that but seems to kick me out at anything about 12mph, below that I can monitor the inputs. No idea it’s been like it since I bought it, huns all look equally crusty so nothing obvious

As I have found, LR Disco 2 hubs can be "gone" or going, without it being obvious at all when you do the normal MOT type tests on a raised wheel. The last one I did just gave a "Thrum, thrum, thrum" noise at low speed and eventually vibration at about 50 mph. Even on taking the hub off, it felt sound just the inside of the bearing showed the rubber bit had deteriorated and presumably some of the balls or rollers in the bearing would be worn or rusty. changed it and the noise went away. You need to find out which one it is.
Either a proper LR diagnostic, a Foxwell will do, to tell you which hub it is, or raise the car so all four wheels are off the ground, set it running in gear then very carefully use a long screwdriver or mechanics stethoscope to listen to each hub in turn until you can tell which one it is. This latter is the only way I was able to find out which one it was as I had nothing on diagnostics and none of the three amigos came on.
Or take each hub off in turn until you can find the one that looks the worse from the inside. but that is very labour intensive!!

Others will have cleverer ways than me! But a proper diagnostic is the best bet.
Be careful though as an independent LR garage told me it was the left rear one that needed doing and it turned out to be the right rear one. And Nanocoms are known to make this mistake.

Thanks for the detailed reply, I just checked it is a fox well one, just stops showing me the wheel speeds/live data after 12ish mph.
I’ll try the test you’ve suggested and hopefully I can get something obvious to show

In that case I don't know why the Foxwell isn't showing you a fault with just the faulty hub. Maybe it isn't serious enough. Maybe it needs all three amigos on at once!!

The light literally just flickers, so I think you are right in saying it’s a misbalance, so as far as the computer is aware everything is fine and that wheel just keeps slipping etc, I may try just driving at 12mph and see if one read out flickers

Not me, @sierrafery ! And he knows his stuff when it comes to electrickery especially!!!
I am thinking a bit outside the box now. Maybe a set of pads is low, or a brake piston is sticking in its calliper.
Best of luck with it!
