Depends on the model vehicle. What year and model?
On the right side of car in the engine compartment. Just behind the battery and next to the fuse covers, is a diagnostic connector. You jumper the te1 and t1 connections and then turn the key to the on position. The light will flash a series of times and you count the flashes in sets of 2. These are your codes. Some jumpers are different and the books can say something else also. I just know this is what it says on the sticker inside my diagnostic connector.
