The light is really your only problem with this? Your car comes with ATTS and you're pissed off about a light? That's like someone bitching that their ABS light is on and they want to make it be turned off instead of actually wanting to fix the ABS.

Here's how you get the light fixed: Fix your ATTS and go back to having four-wheel steering like your car is supposed to have. I'd kill to have a Super-Hicas/ATTS working car, most of them are broken or don't work any more.
