Question

Quizplus · Accepted Answer

Technician A is correct because the "Pass Air Bag Off" light not illuminating when an eight-year-old child sits in the passenger front seat can be considered normal operation, depending on the child's weight and the vehicle's airbag system sensitivity. Modern vehicles are equipped with sensors to detect the presence and weight of a passenger to determine whether it is safe to deploy the airbag in case of an accident. If the child does not meet the weight threshold, the system may decide not to arm the airbag, and thus the light indicating the airbag is off may not illuminate. Technician B is incorrect because a Diagnostic Trouble Code (DTC) would not necessarily set for this condition as it is within the normal operational parameters of the system.
