Exam 60: Airbags and Pretensioner Circuits

When servicing an air bag, which of these is the first step taken?

The occupant detection system re-calibrates at every key cycle.

During an airbag deployment, the vehicle event data recorder (EDR) will record all of these EXCEPT ________.

Before the airbag can inflate, the squib circuit must have a ground. The ground is provided through the actuation of which of these?

Technician A says that air bag electrical terminals are copper-plated to protect against corrosion. Technician B says that pretensioners are explosive (pyrotechnic) devices which remove the slack from the seat belt and help position the occupant. Who is right?

What enables an air bag to deploy in an accident, even if the battery becomes disconnected during the crash?

To cause inflation, the closing of the ________ is required to provide the power-side voltage to the inflator module.

Which air bag system component is shown in this illustration?

On a vehicle equipped with an occupant detection system, how much weight is required in the seat before the passenger airbag deploys at full force?

Keeping the ignition key in you pocket can prevent damage to the clockspring during airbag service.

Which of these is an explosive (pyrotechnic) device that tightens the seat belt as the airbag is being deployed?

Technician A says that two sensors must be triggered at the same time for an airbag deployment to occur. Technician B says that frontal airbags only operate within 60 degrees from center and do not deploy in the event of a side or rear collision. Who is right?

Which of these is the heating element used to ignite the gas-generating material, usually sodium azide?

The force required to deploy a typical airbag is approximately equal to the force of a vehicle hitting a wall at over ________ miles per hour.
