Did your Traction Control work okay with the faulty DSTC button?

I think so. I remember seeing the led indicating the traction control working. It was just the button: I could not turn it off.

DSTC appears to be working okay with DSTC light coming on as wheel or wheels slip so obviously nothing serious. Am replacing the DSTC button though as there appears to be no easdy way to test it with the VIDA Disgnostic tool, and I am in an area where they don't exist. A local service centre has read out the Set codes for me an none affect the AWD/DSTC etc. Just minor faults going bacvk over many years that have now been reset. Replacing the DSTC button is a breeze. Just take the button surround trim off (carefully) and pull out the button from its socket with a pair of long handled pliers.

dstc is always on by default so no panic. you only need to fix the button if you want to turn of traction control. you cannot turn off AYC

It is very easy to test the button and LED in VIDA

Well, I have replaced the DSTC button but it does not disable the DSTC so that's NZ$100 down the gurgler. Have tried various combinations of button presses to no avail, and have also tried switching the button press to another socket, without success. There are no DSTC faults showing, so it looks like I will have to just accept that perhaps the DSTC button has been permanently disabled at some stage. The DSTC light on the dash continues to flash whenever I pull a wheelie, so assume that the Traction Control function operates as advertised...

Any thoughts would be appreciated.

deffo doing a long press? I'm pretty sure its a couple second press, tho my model is different (2007 facelift is on the stalk)

Have tried every possible combionation of button presses without success. Seems like the button haw been disabled rather than faulting, as there are no faults showing via OBD2 diagnoses and TC still works as advertised.
