Toyota Hilux Traction Control button unresponsive

[CJhilux]

Hi all.

Hoping for some advice. 

I have a 2014 mk7 hilux 3.0 invincible manual, and this weekend I discovered the traction control button is unresponsive.
 

The traction control does however switch off “light comes on and stay on in the instrument cluster” when in 4L

I checked fuses, switch and plug, also replaced switch - nothing.

I checked to see if any error codes and nothing -Tried as per manual, just pressing it, then what I seen on some forums re pressing 3 seconds, even tried 5 seconds, it just does nothing, no light on the switch nor the instrument cluster.

Tried doing a search online but not much…

Many thanks
