How it's done: When the Check Engine Light is on, your carâs monitoring system will have fault codes that indicate the nature of the problem. Your car may have one or more problems and hence there can be multiple codes. The mechanic will read the codes using a scanner, interpret the codes, and provide a diagnosis.
