Can anyone tell me where the earth point for the SLABS is
Had search on here and manual can’t find anything
Thanks mark

Good point! There's more than one. If you mean the earth, CO561 for the SLABS modulator, it is behind the air box. You need to remove the air box to see it. If you mean CO362 for the SLABS ECU, that's interesting because it is missing from the RAVE electrical library. It is roughly shown in the diagram below, which would make it quite close to the SLABS ECU itself.Can anyone tell me where the earth point for the SLABS is

Any earth fault would trigger 3 amigos, there can't be an earth fault to mix up only the TC, better describe what's happenning and if you dont get 3 amigos forget about chasing earth pointsThanks
Iam looking for any earth that may relate to or cause issues with TC
Yes, it just sits in rubber bungs.I take it air box is the air filter housing as I call it
Can I ask where you found the picture of CO362? It's not in my version of RAVE or the pdf version elsewhere on the internet. Thanks.Like said, the SLABS ECU earth terminal id is C0362 which is fed to pin 12 on SLABS connector C0504. These images should help you locate it :

Might be an intermittent bad connection(not as bad to be open circuit which would trigger the amigos) in one of the sensor's plugs or at the ECU plug which gets the sensor inputs, or there is play in one of the reluctor rings and when the symptom occurs one of the wheel speed inputs gets different than the others so the ECU considers it a wheel spin hence it activates TC. As i said it has nothing to do with earth, it's something on the speed inputs path . The worst scenario is ECU or modulator misbehaviour. Give some contact spray in each sensor's plug and in the ECU plugsIt this on going twitchey TC all wheel bearings good all read 1100 ohms
So you go down very ruff farm drive nothing happens
Continue down normal road and then suddenly after day a mile the TC goes nuts for no reason then after a few miles back to normal
I thought bad connection but you would think the ruff farm drive would set if off
Sorry when plugged in all wheels show same voltage and no faults are logged
Trust me it’s a very odd one had motor 10 years had land rovers for 40 years so I do know a bit about them but this has me flummoxed

That's correct, though the bad hubs have usually 55 teeth insted of 60 and no other way to figure this out other than remove the sensor, make a mark on one slot and turn over the hub to count the teeth... quite many such cheap hubs on the market these days... though if it was that it should have misbehaved from the beginningSo one of my newish front hubs could quite conceivably be say 1 tooth short and it wouldn’t be picked up or show on any readings
Just do no more than make the TC over react
