Load Beeping, Then Solid Beep, Then VSC Light

[AnotherCO4Runner]

Let me start by saying I was in 4L and in L gear, climbing a fairly steep gravel trail (CO 602A). I am doing fine and then loud beeping, then solid beep and the VSC light comes on. So when I got to a level spot i stopped, put it in neutral and then back in D. Light goes away, beep stops.

Other than that the day was flawless. What happened there and should it concern me?

slip control indicator on 01 and 02 runners,when wheel slippage is detected. Some do the Andy mod to disable the vsc, track mode off via toggle switch.
