Thread: TC will not stay/turn off at maximum Articulation

Peter what you are seeing is normal.

If you don't have a cross axle diff lock and you disable TC.. the diff on that axle will simply put all the power to the wheel with the least resistance... i.e. One wheel will spin the other will remain stationary. That is exactly what an Open Differential should do - As you saw.

I suspect that without diff locks, you will get far further by keeping the TC turned on rather than turning it off.

Thanks Bytemrk,

I thought that to be the case.

I mostly do sand driving and although the TC is good. I find it maybe not a hinderance to where i go but more annoying, loud and a speed restrictor.

Thanks again though

TC is only a hinderance if tyre pressures are incorrect.

I've got a 90 aswell, and do heaps of dune bashing, I've got bfg mt tyres( which aren't great in sand) , I let them down to about 15psi, I find the traction control to be very good aid , I wouldn't ever turn it off.
I havnt been bogged in the yet , but last time I was at wedge island my friends 60 series cruiser with a 4inch lift kit got very stuck both diffs in sand, the 90 just pulled through the same patch he got stuck in.
I would say it's your tyre pressure letting you down it makes a massive difference.

Was your centre diff lock engaged? In sand, I find locking the centre diff reduces the number of times that TC comes on.

Not locking the CDL on low traction surfaces is a great way to destroy the TC. The unit isn't suited to massive loading through it.

Always lock on low grip surfaces...

I had traction control turned off when I went into it and even though the light was telling me the TC was off, only two of the wheels were spinning.

I had another play today and tried to get to maximum articulation and had the same problem.

I was hoping I could get away with not getting front and back lockers with the new TC switch.

Has anyone had this problem or can tell me why and how I can avoid it.

thanks in advance

Pete, that button on the dash only turns off the stability control not the traction control.
If you're in a pinch, you can pull out the fuse for the ABS system to disable it. I haven't had to try it myself yet though.

With the ABS disabled you could then try a bit of pressure on the brake pedal to control the wheelspin.

Hope this helps
Cheers

I really don't understand this thread.

Traction control is designed to brake the wheels that are spinning to send power to the wheels that are not.

A mistake many make is not pushing the accelerator enough to activate it.

Mine in D2 works best doing exactly what you don't do with an open axle ( ie add acceleration when you stop in say wombat holes) and it is an automatic way of putting your foot on the brake pedal.

It takes a bit of time on a river exit because the brakes are wet, but it worked fine for me on the Murray River exit at Tom Groggin with 2 wheels a foot off the ground.
I also tried mine out at Stockton and it was fine , with correct tyre pressures and backing off it it went off when not needed, say up a cut up dune
