Disabling traction control

[mtb_gary]

Driving in the soft sand around Wilbinga yesterday and the traction control was forever cutting in and killing a lot of forward momentum, to the point where the car would stop then continue on again. Whilst left foot braking disables the traction control bouncing over some of the bumps can make this less than desirable to keep steady throttle. I was wondering if anyone has a dash mounted switch to switch of the traction control?
Is it as simple as effectively turning on the brake lights?

How does TC stop momentum?

It only brakes the wheel without traction that is not providing momentum anyway - I have been driving TC fitted landies for 10 years and never had this issue. Yes DSC kills the RRS if it is on but never the TC. The Feelander 1 never had an issue in sand.

If you are finding that it is TC causing your lack of momentum issues, then I would say there is some sort of fault in the system.

I'll second those thoughts.

Tyres at the right pressure, I've not experienced an issue with traction control stopping momentum in sand.

Hi

I can third that, I have never even felt the TC working on sand.

When I did the course, we dropped mine to 14 psi, the instructor said it looked like it wasn't "floating" as it should when I had them at 16 PSI

So maybe try some variations on tyre pressures

Spinning wheels do not add to forward motion, they only dig holes.
The secret is to ease off the right foot and allow the TC to do it's job.

It's amazing how much faster (and further) you go when your wheels are not spinning and digging you in. :o

mtb garry is yours two or for wheel tc?

I've not had any issues with the two wheel tc. But, that was at 16psi or below. At 24ish on dry sand it was working hard - but didn't suck momentum.

Maybe your viscous coupling is buggered? In mums D2 I used to have that issue when the tire pressures were wrong (unexpectedly boggy sand) and there was no centre diff lock, so yes it does happen, in such that traction control can be seen as a disadvantage in my opinion, though this is only ever in soft sand without a CDL, and incorrect tire pressure usually contributes.

My D1 seemed to go better with the CDL unlocked than the D2 with CDL unlocked and traction control, only because the braking front wheels slowed it down.

But yeah, check the VC and adjust tire pressure.

Thanks guys

I know the tyre pressure was too high, sitting around 24psi, but did not expect the TC on the rear only to activate to the point of stopping the car? As for the VC it was replaced only a few months ago so I am assuming all is good from that part.
Next time up there definitely let the pressure way down in the tyres!

Good idea! Even if its a short run on the sand, ill always let the tyres down. Especially important with an auto!

Hi Gary, I have 285 75 16 mud tyres on my 1996 P38 with rear TC only and when I took it to the beach a while back I went into the dry loose sand at the top of the beach, stopped there and took off from standstill a number of times in order to see how the tyres handled the soft sand. I had 14 psi in the tyres and and was mindful of taking off gently and there wasn't a hint of wheelspin I also drove in circles in the soft sand and there wasn't a hint of wheelspin at any time and never an indication that the vehicle would come to a halt.

I don't know what sort of suspension system you have on your vehicle but I am of the opinion that if you have airbag suspension on it then you should be mindful of not driving it in high setting on the sand but on normal setting in order to maintain a soft suspension and a willingness to articulate without being limited by the either the anti roll bar, shock absorber or an extended airbag.

P38oncoils, I am on air with a HRA 2" lift. At the time I was running in normal mode, with plenty of articulation as noted by my mate in a prado behind me (he was unable to get up a couple of tracks with the large deep articulation testing holes in it that the p38 got up without wheel spin). Prior to the stopping I had the brake fluid low sign come up on the dash, when descending a steep dunes. This has since been topped up as it was indeed just below the minimum line when charged. When the car stopped in the deep soft sand all 3 amigos came on, then went off almost immediately after stopping. In hindsight (20/20 vision) yes I should have let the tyres down, way down from 24 as well as ensuring the brake fluid was topped up to the maximum level. I had the 265/75/16 bighorns on at the time and know they can comfortably run around 12psi without bead locks on the standard p38 rims. This weekend I'm back out on the water with the boat, but maybe next weekend I may be able to get back up to the dunes around Wilbinga to give it another try :D.
