Technician A says that a wrong tire size installed on a vehicle can set a fault code in the electronic brake control module. Technician B says that you should use service information to determine how to diagnose the problems and locate the cause of faults in the electronic brake control system. Who is correct? a. Tech Ab. Tech Bc. Both A and Bd. Neither A nor B

Both

Explanation:

They are both right. The first technician who said wrong tire size installed on a vehicle can set a fault code in the electronic brake control module was right. Because the size might alter the alignment of the vehicle, hence triggers the censor. He probably spoke from experience. The other technician who stated otherwise knew such fault code might have risen as a result of something else, so using the service information will give the precise diagnosis.
