TSB (Technical Service Bulletin)


Technical Service Bulletins or TSBs are document procedures for vehicle repairs that are issued by a vehicle manufacturer when several occurrences of an unanticipated problem occur.

  • The TSB may consist vehicle specific technicalities and step-by-step procedures, which are written by engineers and automotive mechanics.
  • It helps the technicians to save troubleshooting time, provides organize the arrangement of itemization for vehicle repair procedures, standardizes the operation workflow, and enhances quality service and maintenance because of the repair history supported by high-level diagnostic procedures.
  • It also serves as a reference among the dealership service department and technician to have the centralized knowledge for the vehicle issue

The Technical Service Bulletin is different from a Recall. A recall is a compulsory vehicle repair even if the vehicle is already out of warranty because it involves the safety of the driver, however, the TSB is not required by the vehicle manufacturers since it is only detailed technical documentation with an engineering level of description for a vehicle issue and can be free of charge as long as the vehicle is still in its warranty claim period coverage.
