List three items to check when inspecting a seat belt.

Seat belt retractors are being discussed. Technician A says that when the belt is suddenly jerked on a webbing-sensitive retractor system, the retractor should lock up. Technician B says a vehicle-sensitive retractor can only be tested by braking the vehicle at speeds of 5 to 8 MPH. Who is correct?

Always disconnect the negative battery cable and wait the recommended time before attempting any service on an air bag system.

Which of the following factors is NOT used in determining the intensity of air bag deployment in an adaptive (two-stage)air bag system?

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?

List three types of air bag safing sensors.

Air bag warning lamps are being discussed. Technician A says an air bag system problem is indicated if the lamp is on while the engine is cranking. Technician B says on some older vehicles a jumper wire placed between two terminals of the DLC can be used to retrieve air bag system codes if a scan tool is not available. Who is correct?

All model year ____________________ and newer vehicles must have a system that allows for air bag suppression when infants, children, or small adults are in the front passenger seat.

An air bag will fully deploy within thirty milliseconds of impact.

List the three functions of the air bag diagnostic monitor.

The ____________________ allows the electric signals from the air bag electronic control module to connect to the driver's air bag module while allowing the steering wheel to rotate freely.

Technician A says that the clockspring is located at the bottom of the steering column. Technician B says that the clockspring maintains electrical contact between the inflator module and the rest of the system. Who is correct?
