You can reset and turn off the dash warning lights on your Mazda RX8 right from your home garage, saving yourself time and money. When you see one of these lights illuminate on your instrument panel, you need to have the vehicle looked at and repaired by a qualified mechanic. All of the mechanical and electrical functions of the vehicle are monitored by the On-Board Diagnostic computer. The computer receives trouble codes from sensors positioned throughout the vehicle and it alerts you to any problems or servicing needs of the Mazda via warning lights on the dashboard.
