What is Technical Service Bulletin?

Technical Service Bulletins (TSB) are issued by the car manufacturer to assist technicians with diagnosis and repair. TSB addresses specific concerns or conditions such as rough idles, noises and rattles. These specific concerns can be the result of customer or repair shop feedback. The TSB for a specific concern or condition will provide an up-to-date engineering-approved vehicle modification, repair procedure, or service part.
