Do you mean "TBS", or "TSB"? TSB in the auto industry is short for "Technical Service Bulletin". A manufacturer may issue a TSB for a specific issue/problem that needs to be serviced, but would not require a "recall". The Service Department at a dealership would have a computerized list of TSB's for the automobiles they sell/service. Usually, if an auto is repaired for a TSB item, the customer does not have to pay for the repair--parts, or labor.
