There is no such thing like brake traction control except the ESP which works on road like in any other car.
If I understand you correctly, and I am aware English isn’t your first language so I may have misunderstood, if you are saying Grenadier doesn’t have offroad traction control that is incorrect unless you have the front and or rear diff locked, in which case it is disabled. If by ESP you mean ESC (electronic stability control) that is a related but different thing and it is more about on road use and it is actually a hindrance in many situations off road and should usually be turned off, particularly in sand.
It is not only about "first language" (can be ) but also about the new, changing, and complex technology nowadays.
Fair point
Robert was not the first person I saw reference this hence my question. It seems it works, just slowly and may be helped a bit by mild left foot braking.
That's the interesting part. I dare to ask: Is it the case that a grenadier applies the brake in the event of loss of traction as previously described when the lockers are open? If so, I actually missed something.
Yes, ESC. In German the 'P' means 'Programm', in English you seem to say 'control'. Yes, that's what I mean.

Yes you have missed something, with open front and rear diffs the Grenadier will use brake traction control to slow a wheel that is spinning faster than the others. It isn’t as sophisticated or as quick to activate as the better systems but it does.Thank you @AnD3rew for bringing this up.
I'll try to make clear what I am wanted to express.
I was referring to what the thread opener asked:
So it was not about offroad but about the 'brake' thing: I associated "brake" traction control with what e.g. a new Defender does: Stopping a spinning wheel by applying the brake to this single wheel. In that context, I still think that the Grenadier does not apply the brake to a wheel in an off road scenarios to achieve traction in case the lockers are open.
But I stand corrected if I missed something.

I agree with you and have also expressed that above (at least I tried to
So the questions is for me what I have already asked:
"Is it so that a Grenadier applies the brake as described before upon traction loss if the lockers are open?"
PS: I thought that ETC/BTC (?) is for Hill Descent Control. But as said, I may be wrong.
As part of the ESC for stabilization purposes (which I know and which is road-focused), or for what @Ragman asked for, namely traction control (which is off-road-focused) ?
Emax,
In the Pepper video the Gren driver was following instructions and was using light throttle inputs when compared to the other drivers. While I think the Gren system is less sophisticated than the Toyota it could have done with a bit more wellie on the gas pedal to make it activate sooner.
That's a good observation. When you compare that video to the one posted by @Michael H. the Grenadier BTC seems to perform better in Michael's video. Different driver technique and minor calibration differences perhaps.

Open differential is torque equalizing device. Both outpus shafts have the same torque due to the mechanics of differential gears. Only if one wheel is in the air both shafts have zero torque. Traction control uses brake on the spinning wheel and this same torque is then available for the wheel on the ground. Because of same torques but possibly different rotational speeds open differential doesn't supply same power to the wheels despite often claimed.
