ESC Off- reduced only?

[Pfk]

Reading through the owners manual, I am understanding that the ESC is never off completely in the Grenadier, only reduced. Also reading through the fuse switches, I see it cannot be disconnected as it’s tied to few other things.

I was under the impression that Esc would be completely off if one was in a situation such as soft sand, especially where you don’t need differentials locked or low gear on.
I see many modern suv today with esc almost off which tend to fail on sand dunes due to the emergency traction not being completely off..

Am i correct to assume the Esc will work in situations we least want them to work ?

I think it will be fine. Thats the same in pretty much all modern 4x4s and I haven’t had issues eith it when turned to the off (reduced) modes

Since ESC automatically goes into ‘ESC Off-Road Mode’ when the centre diff is locked or Off-Road mode is engaged, I’m hoping that pressing the ESC OFF button is what's needed for sand.

It states to DEACTIVATE ESC and that you will have reduced stability when you do that
The only alternative would be to say you will have NO stability which is not possible as all cars have some inherent stability.

I'm afraid you've lost me there, Dave.

It is very similar to my FJ Cruiser , it has the ESC traction button you just hold for more than 3 seconds and turns off ESC.

The switch turns the Electron Stability Control Off which leaves you with reduced stability of the vehicle as if it had no ESC at all.
So just like cars before ESC was invented.
The driver supplies the stability control

Yes. That's what I’m hoping for.
The OP was worried that the term ‘reduced stability’ might imply that some electronic stability control would continue to operate (at a reduced level) when the ESC OFF switch was pressed, which would be less than ideal In sand.
The fact that there is a reduced level of stability control operating when the centre diff is locked or Off-Road mode is engaged (as shown in the middle column of the table) suggests that the ESC OFF button does turn it off completely.

I recall one of the demo drivers stating everything is off it is now only the driver and the vehicle
That was in low centre locked

Me too!
The reason I mention this is
I was out in my ram the other day with some friends in their 4x4s (Jeep wrangler, G63, and another older ram).
We did not deflate as they were Easy dunes with some soft sand in some parts and we were going close off the road.

In my ram, I have a tsc off button as well, and a long press hold for 10 seconds deactivates Esc.
Did that as usual, but the car kept locking up on a particular dune whereas all the others did not. The wrangler and g63 infront of me did not have that issue..

It was just strange that with both functions off, the car would just choke on the incline of the dune. Tried it 3 or 4 times and gave up went around another one.

I know this wouldn’t have happened if we deflated but still shows that with the electrics, can’t be too sure.

Anyways I’m hoping their OFF function is better than the OFF function I have in my truck.
