The first step in finding the cause of your engine light is to retrieve the trouble codes stored in your car's computer. This can be done by using a code scanner, which is a small, handheld device that plugs into your car's diagnostic port. Once you have the trouble codes, you can look them up in a code book to find out what they mean.
