Technician A says that a deployed airbag can be repacked, reused, and reinstalled in the vehicle. Technician B says that a deployed airbag should be discarded and replaced with an entire new assembly. Who is right?

B only

A vehicle is being repaired after an airbag deployment. Technician A says that the inflator module should be handled as if it is still live. Technician B says gloves should be worn to prevent skin irritation. Who is right?

Both A and B

The electrical terminals used for airbag systems are unique because they are

Gold plated

What unit of electricity is used as a signal for a computer?

Volt

The arrow in a symbol for a semiconductor device

both a and c (points toward the negative, is attached to the emitter on a transistor)

Analog signals from sensors are changed to digital signals for processing by the computer through which type of circuit?

Analog-to-digital converter

Where are shorting bars used?

At the connectors for airbags

What two things can a vehicle computer actually perform (output)?

Turn something on or turn something off

the forward-bias voltage required for an LED is

1.5 to 2.2 volts

Driver and/or passenger front airbags will only deploy if a collision occurs how many degrees from straight ahead?

30 degrees

Which item is a computer input sensor?

All of The Above (RPM, Engine coolant temperature, Throttle position angle)

Which item is a computer output device?

All of the Above (Evaporator emission control solenoid, Fuel injector, Transmission shift solenoid

A seat belt pretensioner is

All of the above

The "brain" of the computer is the

CPU

5. Computer speed is measured in

Clock Speed

What conducts power and ground to the driver's side airbag?

Clockspring

All OBDII vehicles use what type of read-only memory?

EEPROM

The four basic computer functions include

Input, processing, storage, and output

Two technicians are discussing two-stage airbags. Technician A says that a deployed airbag is safe to handle regardless of which stage caused the deployment of the airbag. Technician B says that both stages ignite, but at different speeds depending on the speed of the vehicle. Who is right?

Neither A nor B

The SAE term for the vehicle computer is

PCM

A semiconductor is a material

With exactly four electrons in the outer orbit of its atoms

What color are the airbag electrical connectors and conduit?

Yellow

An LED can be used in a

all of the above (headlight, taillight, brake light)

another name for a ground is

all of the above (logic low, zero, reference low)

A transistor can

all of the above (switch on and off, throttle, amplify)

Clamping diodes

are connected into a circuit with the positive (+) voltage source to the cathode and the negative (-) voltage to the anode

A transistor is controlled by the polarity and current at the

base

A diode installed across a coil with the cathode toward the battery positive is called a(n)

clamping diode

A zener diode is normally used for voltage regulation. a zener diode, however, can also be used for high-voltage spike protection if connected

positive to cathode, ground to anode

How many sensors must be triggered at the same time to ause an airbag deployment?

two
