Occupant Restraint Controller System (LV2)

A. General Topics

Which statement describes the only safe way to disable the airbag system for servicing?

• . Disconnect and Isolate the negative (ground) cable. Wait two minutes for the capacitors to discharge.

• Use a scan tool to disable the appropriate controllers

• Verify that the ignition is off for at least 30 seconds.

• Disconnect the positive cable. Wait one minute for the capacitors to discharge

Which statement describes the appropriate repair for a torn front seatbelt?

• Replace the seatbelt with the correct used part

• Replace the seatbelt with the correct new part.

• Use the seatbelt repair kit to sew the torn seatbelt.

• Replace the torn seatbelt section with new webbing

What is the purpose of the sheet strap in an energy absorbing steering column?

• . It winds up to hold the airbag in the correct position for maximum occupant deceleration.

• . It prevents the column from folding upward and ejecting the driver

• It permanently retains the upper and lower column segments.

• It unwinds during an impact event thereby absorbing energy.

A. General Topics

What is the safety goal of crumple zones?

• It minimizes damage to the vehicle by providing a very rigid structure behind the bumper areas.

• It reduces the severity of an impact by transferring as much damage as possible to the other vehicle.

• It allows the passenger compartment to crumple as much as possible

• It minimizes the transmission of kinetic energy to the occupant by reducing the severity of deceleration.

A. General Topics

For most vehicles, where is the occupant restraint controller (ORC) mounted?

• Behind the PDC

• Behind the glove box

• In the left or right kick panel

• In the center console or center stack area

A. General Topics

Which is the correct procedure for a dropped occupant restraint controller (ORC)?

• Straighten any bent mounting tabs and reinstall.

• Run the ORC initialization routine and check the collision count.

• Scrap and replace with a new ORC.

• Verify proper operation and reinstall.

A. General Topics

Which item directly affects the deployment of supplemental restraint system (SRS) components?

• Vehicle speed

• The weight of the driver

• The angle and severity of an impact

• The level of braking force prior to impact

A. General Topics

Which is the correct way to read the resistance of a squib circuit?

• Use a digital multimeter set to resistance.

• Read the values from the occupant restraint controller data page with a scan tool.

• . Calculate the values by measuring voltage drop across the squib.

• Use an analog ohmmeter

A. General Topics

What is the key factor that distinguishes "active" from "passive" restraints?

• Passive restraints do not provide supplemental restraint.

• Passive restraints require explicit action by an occupant.

• Active restraints require actuators for deployment.

• Active restraints require explicit action by an occupant.

A. General Topics

When do active head restraints deploy?

• Rear impact unless the transmission in reverse

• Rear impact regardless of the transmission selection

• . Side impact unless the transmission is in neutral

• Front impact regardless of the transmission selection
