What Is a Factory Service Manual?
A factory service manual, often called an FSM, workshop manual, or shop manual, is technical documentation created for servicing and repairing a particular vehicle or equipment line. These publications are generally written for dealership technicians, mechanics, repair facilities, and experienced owners who need detailed vehicle-specific information.
Depending on the publication, a factory service manual may include diagnostic procedures, component removal and installation instructions, torque specifications, service limits, adjustment procedures, testing methods, maintenance information, electrical troubleshooting, and other technical data needed to properly service the vehicle.
