Which data bus system of the 2019 A6, A7 and A8 is capable of operating (properly) in single wire mode?

• Powertrain CAN

• Convenience CAN

• LIN bus

• Both the Powertrain CAN and Convenience CAN

What is the purpose of the shunt resistor in the J367 Battery Monitoring Control Module?

• Measuring battery temperature

• Measuring charge and discharge current of the battery

• Sending and receiving LIN signals to J533

• All of the above

When talking about a pulse-width modulated signal that has a total period length of 10ms. If there is an on time length of 3ms, what is the duty cycle of the signal?

• 70%

• 3%

• 10%

• 30%

What is important to know when checking power supply of a control module using measuring value blocks?

• The scan-tool sampling rate is too low and the DSO should always be used

• Measuring value blocks always show the peak voltage of a control module

• Control modules often have several power supplies, which cannot all be tested via MVBs

• You cannot read voltage readings in MVBs

When the temperature increases, the resistance of an NTC (temp. sensor)...

• Decreases

• Increases

• Decreases until the sensor reaches 45 degrees Celsius and then increases

• Does not decreases or increases because it works on Hall principals

• Battery positive

• Chassis ground

• Load reduction

• Switched power

• AM/FM antennas

• GPS antennas

• Rear view cameras

You can pair and switch between two phones in the MMI system

• True

• False

Which of the following are control module functions?
