Locate the self test connectors on the drivers side inner fender well. You can find these, by finding the one which looks similar to the shape of a house. Hook up with a jumper wire as shown in the diagram below. Turn your key forward onto accessory (KOEO, key on, engine off), and wait for the codes. Codes will start with an 11 (meaning ok/done or ready) followed by any thrown codes, then will end with an 11. (note, that if no codes are thrown, and 11 will appear just once). Fix any codes from the KOEO test before you do the running test (KOER, key on, engine running). Finally when finished reset your cars computer, do this by disconnecting the negative side of the battery while leaving your headlights on for 20 minutes.
