Technical Service Bulletins (TSBs) are recommended steps and procedures for repairing vehicles. A TSB is issued by an automaker when there is a growing trend with an unanticipated problems, but does not warrant a recall.
Click and Clack of Car Talk succintly described TSBs as a document “containing advice from the company to the mechanics who fix [the] cars.” Automakers create TSBs to summarize specific problems with their cars and the recommended steps to make those problems go away. They can range from covering specific vehicles to covering entire model lineups.
Have you ever had an annoying problem, only to be told by the mechanic they couldn’t duplicate the problem? That’s the worst. THE. WORST.
TSBs can help service technicicans troubleshoot a problem, even if they can’t replicate it.
They also provide step-by-step repair instructions and itemized lists of parts and part numbers. All of that adds up to save the technician time – and when they save time, you save money. I mean, have you ever looked at the hourly cost for service? Yikes.
