Hey guys. I have a 2005 land cruiser and there are some exit ramps I take that are downhill and turn to the right to merge onto the highway. I don't know if its because of angle or speed, but sometimes the car decides to apply the brakes to the outer wheel. It's annoying. Especially because it happens while driving and I am fully aware that the car is not in any danger of tipping. Is there something wrong with the car? How can I disable traction control? It also interferes too much if I want to go into the desert. It keeps killing my momentum.
Why does my traction control keep engaging while driving?

You might have a wheel speed sensor problem. Mine had some issues with that after I had been driving in slushy snow. It was a bit more than annoying. The brake would apply hard enough to pull the LC in whatever the braking direction was. Down here in warmer country it causes the cruise control to drop out every now and then
Certainly could be an intermittently defective wheel speed sensor, or could be as simple as tire low pressure or mismatched tires.
Trac activates when you get wheel spin so it sounds like it's functioning as designed when you're in sand. VSC - slip control - activates when the stability algorithm decides your vehicle is becoming, or is, unstable. It uses wheel speed (hence the comments to check tire pressures and speed sensors), steering wheel angle, accelerometers and a couple of other inputs.
During a turn the outer wheels rotate faster than the inner wheels = different speeds reported, but the ecu accepts this as reasonable because of the steering angle input. If you have one or more flattish tires, or an odd sized tire, it rotates at a speed different to the others and the ecu may identify this as tire slip and instability and apply VSC braking to regain control.

I'm sure my tires were within 1-2psi of each other.
I don't know if its the car or because of the VSC, but the LC100 suck in the desert/soft sand. Also the ground clearance is pretty horrible when compared to a jeep

What size / kind of tire are you running?
Jeeps are lithe and light weight. Land Cruisers are "big boned"
Put a big fat tire on a Jeep and it'll make sand look like pavement.

You probably know this but sand and wide tires go together.
Just a guess but I think Occam's Razor applies here. It's probably an intermittent wheel speed sensor

Gotta admit, that is really strange to hear. My 02' LC is an absolute soft sand monster and I have the stock Michelins on. I've never gotten stuck - in fact, I pulled out my friends stuck Tacoma (off-road package with rear locker) from some soft sand WHILE IN SOFT SAND.
Yeah no issues in sand or mud here either. Tires have a lot to do with it but that's for any vehicle. LC's are heavy so they dig in faster, it takes some getting used to, but once you are really familiar with your LC it will almost never let you down.
