Question 1: How does regenerative braking contribute to the overall efficiency of an electric vehicle's power system?

Which action should you take?

Choose only one option

By converting kinetic energy into electrical energy, which is stored in the battery

By decreasing the battery voltage during braking

By reducing the need for cooling in the power system

By increasing the weight of the vehicle

Question 2: What is the purpose of the ground fault detection system in automotive electrical systems?

Which action should you take?

Choose only one option

To manage the flow of electricity to auxiliary systems

To regulate the electrical flow to ensure safety

To store power in case of electrical failure

To detect and prevent potential electrical hazards by monitoring ground faults

Question 3: How do you address a malfunction in the car's airbag system that's not deploying during a crash simulation?

Which action should you take?

Choose only one option

Replace the airbag module without testing the sensors

Focus only on the airbag module without considering wiring

Ignore the electrical components and focus on mechanical issues

Use a scan tool to check for diagnostic codes, then verify the wiring and sensor functionality

Question 4: What is the main advantage of using a fuzzy logic controller in automotive applications?

Which action should you take?

Choose only one option

It allows for more flexible control by handling imprecise input and offering approximate reasoning

It uses linear models to control complex systems

It operates faster than traditional PID controllers

It reduces the overall system complexity and cost

Question 5: How do you troubleshoot an issue with the car's infotainment system, such as no power or malfunctioning screens?

Which action should you take?

Choose only one option

Inspect the fuse, check for proper voltage at the power supply, and ensure the wiring is intact

Focus solely on the screen without inspecting the power connections

Test only the antenna and ignore the electrical connections

Replace the infotainment unit directly without testing

Question 6: What is the main advantage of using CAN FD over traditional CAN in automotive networks?

Which action should you take?

Choose only one option

Higher data transmission rates

Simplified wiring

Enhanced compatibility with legacy systems

Lower cost implementation
