TRC off... maybe u pressed a button or something something that switched your traction control off. If so, just press it again when ur done drifting like one guy said...
If VSC always on... dunno, maybe u screwed the Vehicle Stability Control and it needs checking...
What button function is this ?
I think from Evo 7 onward all model will have this button, but I really duno what function is that.
Anyone know and mind to share a bit ?
