I can't stress enough how important it is to have a repair manual for your vehicle if you are going to do any home repairs. All these cars today do have great computer systems that will diagnose in "trouble codes" But these are not a direct diagnosis of the problem, only the area of fault to start in. A good repair manual will list each of these "Trouble Codes" and direct you in how to pinpoint the exact problem. There are also computer readers you can buy that will also give you a starting point, but without a manual or great knowledge about your vehicle it can lead to costly replacement of parts you don't need.
