The most basic of vehicles have a minimum of 30 microprocessor-controlled devices. We call these ECU’s (electronic control units). Luxury cars can have 100 ECU’s! These processors make it difficult for the average person to work on their own vehicle but it makes it easier for auto repair shops as they have made an investment in the right equipment and diagnostic tools in order to translate trouble codes and determine what is actually wrong with your vehicle.
