Bluetooth mode can be activated/deactivated in Adaptation for what module/s on a 2021 A6?

• J794

• J533

• J623

• J393

What happens if the fiber optic signal is interrupted on the MOST bus?

• The fiber optic module reverses the signal at the point of the fault to allow the system to still communicate

• The Diagnostic Wire is used to determine where the fault occurred on the fiber optic system

• The Infotainment CAN bus is used to allow the system to still function

• The MMI screen displays a communication fault

If there is no communication from one control module on a MOST bus. What happens to the communication on the rest of the network?

• The entire network shuts down

• The control module before the fault reverses communication on the fiber optic cables to ensure that all other control modules can still communicate and allow functionality of the rest of the network

• A default communication signal is sent to allow the control module that is not communicating to be ignored

• Communication takes place over regular wires instead of the fiber optic cables

Technician A states that when a Ring Break Diagnosis is performed on the MOST bus, all control modules on the MOST bus are electrically checked. Technician B states that when a Ring Break Diagnosis is performed, all control modules are optically checked. Who is correct?

• Technician A

• Technician B

• Both Technician A and B

• Neither A and B

In a MOST system, if an ECU fails, what happens to the light signal sent to it?

• It is not passed along to the next ECU

• It continues on to the next ECU along the fiber optic wire

• It is reflected back to the last functioning ECU

• It can be corrupted by the dead ECU

True or False : All of the Modules in the MOST System have a fiber optical transmitter?

• True

• False

What CAN bus is used to communicate when the key fob is used to open the trunk on a 2021 A6?

• Infotainment CAN

• FlexRay

• Convenience CAN

• None of the above

Technician A says when diagnosing a key fob concern that measuring value blocks should be used to check signal strength from antennas to assist with diagnosis. Technician B says that output diagnosis can be used for diagnosing rear latch concerns.

• Technician A

• Technician B

• Both Technician A and Technician B

• Neither A and B

Technician A says that when a LIN wire is shorted to power a DVOM will show roughly source voltage . Technician B says that when a LIN wire is shorted to ground a DVOM will show roughly .01 volts. Who is correct?

• Technician A

• Technician B

• Both Technician A and B

• Neither A and B

What might occur if a LIN master control module is not coded properly?

• The LIN slave component will only work intermittently

• The Master module will set a DTC

• The LIN slave component will not work, no DTCs will be present

• The Gateway will set a DTC for improper LIN coding
