At all times, the BCM takes priority over the TCM when it comes to module arbitration.

True
False

In the binary code of a CAN and CAN FD systems, 0 (zero) represents the ____________ state.

Aggressive
Reverse
Recessive
Dominant

Terminating parallel resistors in a CAN system must be contained in one of the modules of the system.

True
False

Technician A states that all modules on a CAN bus contain a terminating resistor. Technician B states that all modules on a CAN bus contain a 120 ohm resistor. Who is correct?

Technician A
Technician B
Both
Neither

Technician A states that CAN high and CAN low voltages differ above and below the “resting” voltage by the same amounts. Technician B states that CAN high voltage varies more than CAN low. Who is correct?

Technician A
Technician B
Both
Neither

CAN arbitration is best described as:

Deciding whether binary code is used or not used
Deciding the module priority
Deciding which CAN bus communicates first
Deciding whether CAN or CAN FD is used

In determining the total resistance in a circuit with parallel resistors, the number of resistors makes no difference.

True
False

CAN data travels at up to 16 bits, while CAN FD data travels up to 120 bits.

True
False

Technician A states that in repairing the twisted pair wires in a CAN or CAN FD circuit, stranded wires are the proper choice. Technician B states that solid copper wiring is the best choice. Who is correct?

Technician A
Technician B
