Technician A is correct because history codes indeed remain in a vehicle's computer memory to indicate past faults that have been repaired, serving as a diagnostic tool for technicians. Technician B is also correct because history codes in the airbag controller can exist without triggering the airbag warning light or message, as they represent past issues that have been resolved or do not currently affect the airbag system's operation.
