VSC system clarification please

So I read through a previous thread about this but I’m still unclear about what and how it works with different settings (one push of button, push and hold, 2WD vs 4WD?)

So I guess I’m looking for a dumbed down explanation based on the following pics of my display. Any help appreciated, trolling tolerated only if it’s funny.

1.One push of button/2WD

2. Push & hold button/2WD

3. One push of button/4-hi

4. push & hold button/4-hi

Thanks!

 

The most dumbed down version I have
(Ignore stuff about 2 low)

See sticky for correlation of the dash indications

 

That sort of helps, thanks.

I know what Auto LSD is/does. Maybe I should ask what is the difference and use between TRAC/OFF and VSC OFF systems? Like pics 2-4 above.

 

What is the TRAC system and what does it do? On vs off?

I think I understand VSC, stability control system that activates when truck begins to fish tail, lose traction etc. Moves power between rear tires and engine power reduction while activated?

TRAC just stops it from spinning the tires if you stomp on the gas.

 

Excellent responses! Thank you.

 

Traction control is a system aimed at maintaining grip at the driven wheels only. It looks for wheel spin and intervenes to limit that wheel spin.

VSC aims to keep the vehicle on its intended path. It corrects for skidding out of control.
