Preliminary research may involve talking to the customer, a visual inspection, a scan tool analysis, test drive and looking up any related Technical Service Bulletins (TSB's) on the Internet. TSB's are documents published by the manufacturer that address common problems or updated test information that has been developed since the vehicle was produced. TSB's should be checked to avoid misdiagnosis and needless part replacement.
