The ATTS light came on in my prelude. Whats it mean and what should I do.
Something is wrong with your Active Torque Transfer System. Essentially that's your computer-controlled traction control system. If you don't want to take it in to a mechanic (for this I'd recommend someone that specializes in Hondas), you could use a code scanner to download the error codes from the computer to get more information. Most auto parts stores will have one you can borrow for free to use in the parking lot.
