Question 1

SRS are generally referred to as _____.
A)seat belts
B)desiccants
C)air conditioning systems

B)Red and amber lights are used because they are least distractive for the driver.
C)Yellow warning lights signal an item that needs immediate attention.
D)Green lights indicate that the vehicle needs attention but is still operational.

Accepted Answer

Warning systems are designed to alert the operator to a fault or failure in the vehicle or machinery. Red and amber lights are used to indicate an issue that requires immediate attention, while yellow lights may indicate a less urgent issue. Green lights are typically not used in warning systems.

Question 6

Newer vehicles use a PCM or a separate computer to compute information for the driver information systems.

Accepted Answer

This statement is true. Newer vehicles often use a powertrain control module (PCM) or a separate computer to process and display information for the driver such as fuel economy, speed, and engine performance.

Question 7

Two technicians are discussing headlamps. Technician A says that most headlamps are non-adjustable. Technician B says that headlamps can be sealed or non-sealed units. Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

Technician B is correct- Headlamps can be sealed or non-sealed units. Technician A is incorrect- Most headlamps are adjustable.

Question 8

Interior dome lights and other interior lighting are federally mandated.

Accepted Answer

There is no federal mandate specifically requiring interior dome lights or other interior lighting in vehicles; regulations typically focus on exterior lighting for safety. Interior lighting standards are often determined by manufacturers or may be subject to general vehicle safety and design regulations.

Question 9

Two technicians are discussing OnStar. Technician A says that OnStar is standard on many newer GM vehicles. Technician B says that OnStar can monitor air bag deployment and notify emergency authorities. Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

Both Technician A and Technician B are correct. OnStar is indeed standard on many newer GM vehicles, and it can also monitor airbag deployment and notify emergency authorities.

Question 10

Automobile heating systems utilize engine oil to bring heat into the passenger compartment.

Accepted Answer

Automobile heating systems usually utilize engine coolant (antifreeze) to bring heat into the passenger compartment, not engine oil.

Question 11

Two technicians are discussing vehicle air conditioning. Technician A says that A/C systems utilize a compressor and a metering device. Technician B says that A/C systems require a specific amount of refrigerant to operate properly. Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

Both technicians are correct. A/C systems do utilize a compressor and a metering device, and they do require a specific amount of refrigerant to operate properly.

Question 12

Some instrument panels have LED lights for lighting systems.

Accepted Answer

Some instrument panels do have LED lights for their lighting systems. LED lights offer several advantages over traditional incandescent lights, including longer lifespan, lower energy consumption, and better visibility.

Question 13

GPS systems utilize a land-based transmitter system to calculate the vehicle's position.

Accepted Answer

GPS systems utilize a network of satellites in space to calculate the vehicle's position, not a land-based transmitter system.

Question 14

Most exterior lighting is installed by the manufacturer for aesthetic reasons.

Accepted Answer

Exterior lighting is installed primarily for safety and visibility reasons, helping to illuminate pathways, entryways, and outdoor spaces during nighttime or low-light conditions. Aesthetics can be a factor, but safety and functionality are the primary purposes.

Question 15

Two technicians are discussing refrigerant handling. Technician A says that The Clean Air Act of 1990 authorized the EPA to control refrigerant. Technician B says that anyone can purchase R-12 refrigerant. Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

Technician A is correct. The Clean Air Act of 1990 gave the Environmental Protection Agency (EPA) the authority to regulate the production and consumption of refrigerants that contain ozone-depleting substances. This was done to protect the ozone layer from further depletion.

Technician B is incorrect. R-12 refrigerant has been phased out and is no longer available for purchase by anyone other than certified technicians who have passed the EPA Section 608 certification exam. This was done to prevent the release of harmful refrigerants into the atmosphere.

Question 16

Adjustable pedals were installed in vehicles to allow drivers of different heights to each achieve a comfortable seating position.

Accepted Answer

Adjustable pedals were indeed installed in vehicles to accommodate drivers of varying heights and allow them to find a comfortable seating position.

Question 17

The dimmer switch on modern vehicles is typically a floor-mounted switch that is foot operated.

Accepted Answer

Modern vehicles usually have the dimmer switch integrated into one of the stalks on the steering column, not as a floor-mounted switch.

Question 18

Two technicians are discussing vehicle instrumentation. Technician A says that gauges and lights are the means to convey information to the driver. Technician B says that analog gauges have a numerical readout that changes as the reading varies on the vehicle. Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

Technician A is correct because gauges and lights are indeed used in vehicles to convey information to the driver. Technician B is incorrect because analog gauges do not have a numerical readout; instead, they use a needle to indicate a value on a scale, unlike digital gauges which display numbers.

Question 19

Power seats are typically four- or six-way adjusting.

Accepted Answer

Power seats commonly have the ability to adjust in four or six different ways (such as forward/backward, up/down, and tilt).

Question 20

Two technicians are discussing information systems. Technician A says that only speed and basic operational information is available. Technician B says that vehicle information is only available with a scan tool. Who is correct?
A)A only
B)B only
C)Both A and B
D)Neither A nor B

Accepted Answer

Technician A is incorrect because modern information systems in vehicles provide a wide range of data beyond just speed and basic operational information, including diagnostics, fuel efficiency, and more. Technician B is also incorrect because vehicle information can be available through various means, not just with a scan tool, such as through onboard diagnostic systems, infotainment systems, and even smartphone apps connected to the vehicle.
