Exam 48: Restraint Systems: Theory, Diagnosis, and Service

Which of the following is NOT a type of safing sensor?

A knee bolster is commonly used on ____________________ air bag systems.

List three types of air bag safing sensors.

Trouble code extraction is being discussed. Technician A says codes may be flashed by the air bag lamp. Technician B says a scan tool may be used. Who is correct?

Air bag safety is being discussed. Technician A says to always carry an undeployed air bag module with the trim facing away from your body. Technician B says to carry the air bag module by its wires. Who is correct?

Technician A says that the air bag control module contains the clockspring and the inflator. Technician B says that the diagnostic monitor assembly [ASDM] supplies emergency current to the system if battery voltage is lost. Who is correct?

When placing a live air bag module on a table or bench, face the trim and air bag up.

Technician A says a pyrotechnic-type retractor prevents the belt from coming out of the retractor when there is a sudden pull on the belt. Technician B says an inertia lock retractor uses an explosive charge to quickly tighten the belt at the start of a crash.

After deployment of the air bag, there may be some potentially harmful sodium hydroxide residue on the seats and upholstery.

The air bag control module determines whether the seat is occupied by a child, adult, or a child in a booster seat by inputs from the _____ sensor.

An air bag will be fully deployed within thirty milliseconds of impact.

An undeployed air bag is being replaced because the trim cover is cut. Technician A says the cover can be replaced. Technician B says the air bag must be deployed before it is scrapped. Who is right?

A seat belt that has color fading due to exposure to the sun or chemicals should be replaced.

Technician A says that air bag systems may use up to five sensors. Technician B says all sensors are located in the passenger compartment. Who is correct?

On a ____________________ vehicle, the high-voltage batteries are disconnected from the electrical system when the air bag is deployed.

The side impact air bags deploy at the same time as the front air bags.

Technician A says the SIR warning light should turn on for about six seconds after the ignition is turned on and then turn off. Technician B says that if the SIR indicator is on continuously, the passenger side air bag indicator will display Off. Who is correct?

The occupant classification sensor determines the ____________________ of the passengers.

Occupant classification sensors are being discussed. Technician A says the sensor uses a silicone-filled bladder in the seat cushion that has a pressure sensor connected to it. Technician B says that piezoresistive sensors are located between the seat track and the floor. Who is correct?

Why are adaptive and two-stage air bags [second generation] used on modern vehicles?
