I got a Diablo IN2 last week and innocently (and stupidly - thanks for the warning Diablo :frown reset the tire size in a tune. This immediately threw an ABS warning and ETC warning. I spent a couple of hours on the phone with Diablo last week and they deny the tuner had anything to do with it. Said they suspected a bad wheel sensor. I ran a diagnostic and came up with errors in the TIPM, steering and ABS modules. INPLAUSIBLE DATA FROM ABS. Clearing the errors does not help. It resets every time I start the car. I want to know, short of taking my car to the stealership, if anyone has had luck resetting the tire size to get the ABS module to stop freaking out. The manual states the circumference, in mm, of the acceptable tire sizes. I have attempted to reset the size using the Diablo to match but it still does not clear the codes. HELP!
