What is the purpose of traction control?

Aren’t these truck limited slip rear ends. Why would you want to disable that. We have snow on the ground now and I have been playing with it but really don’t understand it’s uses I guess

You want to disable it under certain conditions where some wheel spin is desired, it will still keep your electronic differential locker.
Read your owners manual to that topic, it explains very nice how it works and where you want to use that button.

It trys to stop wheel spin on take off. Sometimes like trying to start out on a gravel grade when pulling a trailer it will keep you from being able to get moving as you need the tires to spin to get any forward motion. Most of the time just leave it on.

I read the manuel a while back. Still a bit confused. Will test it more on the snowy hills by my house

Simple said, when you push it once it takes away engine rpm control. You can spin the wheels.

The ESC has quite a few pages and of course this is the '22 version, I doubt it changes to a '21 or earlier for that. Same as mentioned above.

Traction Control System (TCS)

The TCS monitors the amount of wheel spin of each of the driven wheels. If wheel spin is detected, the Traction Control System (TCS) may apply brake pressure to the spinning wheel(s) and/or reduce engine power to provide enhanced acceleration and stability.

A feature of the TCS, Brake Limited Differential (BLD) functions similarly to a limited slip differential and controls the wheel spin across a driven axle. If one wheel on a driven axle is spinning faster than the other, the system will apply the brake of the spinning wheel. This will allow more engine power to be applied to the wheel that is not spinning. BLD may remain enabled even if TCS and Electronic Stability Control (ESC) are in reduced modes.

Electronic Stability Control (ESC)
ESC enhances directional control and stability of the vehicle under various driving conditions. Electronic Stability Control (ESC) corrects for oversteering or understeering of the vehicle by applying the brake of the appropriate wheel(s) to counteract the above conditions. Engine power may also be reduced to help the vehicle maintain the desired path.

Oversteer — when the vehicle is turning more than appropriate for the steering wheel position.

Understeer — when the vehicle is turning less than appropriate for the steering wheel position.

ESC uses sensors in the vehicle to determine the vehicle path intended by the driver and compares it to the actual path of the vehicle.
When the actual path does not match the intended path, ESC applies the brake of the appropriate wheel to assist in counteracting the oversteer or understeer condition.

The ESC Activation/Malfunction Indicator Light located in the instrument cluster will start to flash as soon as the ESC system becomes active. The ESC Activation/ Malfunction Indicator Light also flashes when the TCS is active.

If the ESC Activation/Malfunction Indicator Light begins to flash during acceleration, ease up on the accelerator and apply as little throttle as possible. Be sure to adapt your speed and driving to the prevailing road conditions.

WARNING!

Electronic Stability Control (ESC) cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase the traction afforded by prevailing road conditions. ESC cannot prevent accidents, including those resulting from excessive speed in turns, driving on very slippery surfaces, or hydroplaning. ESC also cannot prevent accidents resulting from loss of vehicle control due to inappropriate driver input for the conditions. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ESC equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.

Too long to paste the rest it goes into the modes.
