GENERAL MOTORS: IT HAS BEEN IDENTIFIED THAT THE CURRENT FUEL GAUGE INACCURATE/INOPERATIVE DIAGNOSTICS IN SI-2000 ARE MISSING SOME VERY IMPORTANT INFORMATION. FUEL SYSTEM, OTHER:STORAGE:FUEL GAUGE SYSTEM To get full reports you'll need to register (and pay) on a number of sites that offer them. I highly suggest using the search function as the list isn't the shortest. They are not the complete reports, but just titles that hopefully help out. Because certain problems may have more than one cause or there are sometimes more than one way to fix a problem, it's somewhat common for there to be more than one TSB for the same problem.īelow is a list of the TSBs for all model years. While sometimes written by engineers employed by OEM's, the majority are authored by the first automotive technician to come up with a repair procedure. TSBs can range from vehicle-specific to covering entire product lines and break down the specified repair into a step-by-step process. Not to be confused with recalls, a TSB is issued by a vehicle manufacturer when there are several occurrences of an unanticipated problem. Technical Service Bulletins, or TSBs, are recommended procedures for repairing vehicles.
