Buzzer tone sandy underbody

[Jakemaca]

I drive a Hilux dualcab SR 2015. On a recent trip to Fraser i started to hear a quiet high pitched buzzer tone every time my car drove through deep sandy ruts and the sand would scrape the underbody of my vehicle. Has anyone experienced the same thing and or knows what it is?

Traction control

Traction control? Did the lights come on? Whenever you lose traction as in sand, the traction control light comes on and it makes a sound.

Hi. I had the trc turned off but not the vsc. There was no flashing lights on dash. The sound only came on when sand hit the underbody.

Vsc will do it too, the light is momentarily on if stability control detects unstable wheel travel.
