They then gather information and data from the computer including the trouble codes that have been stored. They will then reset the codes and run the vehicle to see if they return. The codes return, they know they have an actual problem in that the code is not set by accident. The mechanics will then be able to begin the proper diagnosis of the vehicle and then make repairs.
