Question 1

In what year will manufacturers be required to have compliant rearview camera systems in 100 percent of the vehicles weighing less than 10,000 pounds that they sell in the United States?

Accepted Answer

Manufacturers were required to have compliant rearview camera systems in all new vehicles weighing less than 10,000 pounds sold in the United States by May 2018, as per the regulation by the National Highway Traffic Safety Administration (NHTSA) to improve rear visibility and reduce the risk of accidents.

Question 2

About how many people are killed each year in the United States because a vehicle backed over them?

Accepted Answer

Approximately 200 people are killed each year in the United States due to backover accidents, according to data from the National Highway Traffic Safety Administration (NHTSA).

Question 3

According to collision studies, what percentage of head-on collisions can a driver avoid, given an extra one-half second of warning time?

Accepted Answer

B

Question 4

Which measure do Chrysler, Dodge, and Jeep use to help prevent software hacking on their vehicles?

Accepted Answer

The security gateway module acts as a barrier between the diagnostic link connector (DLC) and the vehicle's internal network. This measure is designed to prevent unauthorized access to the vehicle's computer systems, thereby helping to prevent software hacking.

Question 5

Remote start systems are being discussed. Technician A says they are often used in conjunction with a smart key system. Technician B says the doors are locked before starting the engine. Who is correct?

Accepted Answer

Both statements are correct. Remote start systems are commonly used with smart key systems for convenience and added security, and the doors are typically locked before the engine starts to ensure the vehicle's security.

Question 6

What term refers to controllability of the vehicle during hard braking?

Accepted Answer

Directional stability refers to the vehicle's ability to maintain its intended path during hard braking.

Question 7

Which advanced driver assist system uses an ECU to apply hydraulic pressure to the brakes at all four wheels and reduce engine torque when activated?

Accepted Answer

The active collision avoidance system uses an Electronic Control Unit (ECU) to apply hydraulic pressure to the brakes at all four wheels and reduce engine torque when activated, helping to prevent or mitigate a collision.

Question 8

All of these terms are aggressive modes of operation of an ABS system EXCEPT:

Accepted Answer

Cycle is not an aggressive mode of operation of an ABS system; it refers to the process of modulating brake pressure to prevent wheel lockup, rather than a direct action like apply, hold, or dump.

Question 9

Which statement about menu-driven information and control systems is NOT correct?

Accepted Answer

Toyota was not the first manufacturer to introduce menu-driven information and control systems; several manufacturers have developed and introduced such systems over the years.

Question 10

In a smart key system, what type of signal is transmitted from the electronic key to receiving antennas on the vehicle?

Accepted Answer

Smart key systems typically use RF (Radio Frequency) signals to communicate between the electronic key and the vehicle's receiving antennas.

Question 11

The Subaru Eyesight^® system is being discussed. Technician A says it uses two cameras mounted behind the windshield. Technician B says it can be turned off, but the default is set to ON. Who is correct?

Accepted Answer

The Subaru Eyesight system indeed uses two color cameras mounted near the rearview mirror behind the windshield to monitor traffic and potential hazards. It is designed to be always on for safety, but certain features can be manually adjusted or turned off, though the system defaults to being on for safety purposes.

Question 12

Which statement about a navigational system is correct?

Accepted Answer

Navigational systems are designed to determine the user's current location, often using GPS technology, to provide directions and location-based information.

Question 13

Which device is NOT a dedicated add-on navigational system?

Accepted Answer

SyncNav is not a well-known brand for dedicated add-on navigational systems, unlike Garmin, Magellan, and TomTom, which are established brands in this category.

Question 14

The six levels of autonomous vehicles are being discussed. Technician A says that Level 1 vehicles offer no automation, making the vehicle fully dependent on the driver and his/her abilities. Technician B says that partially automated vehicles allow the driver to relinquish control and become a passenger when the vehicle enters a highway. Who is correct?

Accepted Answer

Level 1 vehicles offer some form of driver assistance, such as adaptive cruise control or lane-keeping assistance, but do not make the vehicle fully autonomous. Partial automation (Level 2) still requires the driver to monitor the driving and be ready to take control; it does not allow the driver to become a passive passenger.

Question 15

All of the following features are included in the Subaru Eyesight® system EXCEPT:

Accepted Answer

The Subaru Eyesight® system includes features such as pre-collision throttle management, pre-collision braking (brake assist), and adaptive cruise control, but it does not include active lane change departure prevention. Instead, it offers lane departure and sway warning, and lane keep assist, which are different from actively preventing lane changes.

Question 16

One of the two types of anti-theft systems used on modern automobiles is anti-theft warning systems. What is the other type?

Accepted Answer

Anti-theft disabling systems are designed to prevent the vehicle from being started or driven if an unauthorized attempt is made, complementing anti-theft warning systems that may deter theft through audible or visual signals.

Question 17

Each GPS satellite has these components EXCEPT:

Accepted Answer

GPS satellites do not have Android hard drives. They are equipped with atomic clocks, computers, and radio transmitters to provide precise time signals and location data to GPS receivers. Android hard drives are not a component used in GPS satellites; instead, they use specialized, highly reliable computing and storage systems designed for space applications.

Question 18

What term means a determination of how far left or right a vehicle has moved from its intended course?

Accepted Answer

Yaw rate measures the rotation around a vertical axis, indicating how far left or right a vehicle has moved from its intended course.

Question 19

Automatic traction control (ATC) systems are being discussed. Technician A says an ATC system uses the same wheel speed sensors as the ABS system uses. Technician B says that with some early ATC systems, the ATC function was also under control of the ABCM. Who is correct?

Accepted Answer

The answer of Automatic traction control (ATC) systems are being...

Question 20

What type of sensors are used to detect yaw rate and rollover?

Accepted Answer

MEMS (Micro-Electro-Mechanical Systems) sensors are used to detect yaw rate and rollover in vehicles. These sensors can measure the rate of turn and the vehicle's tilt angle, which are critical for stability control and rollover detection systems.
