Exam 10: Vehicle Communication Networksvehicle Multiplexing Diagnostics

What system provides the ability to use a single circuit to distribute and share data between several control modules?

DTCs that are assigned to the vehicle's body systems and control modules are called ____.

In the Media Oriented System Transport (MOST) data bus system, what changes light signals into voltage that is then transmitted to the MOST transceivers?

A multiplexing (MUX) wiring system uses ____ that connect each module and allow for the transporting of data from one module to another.

Technician A says the LIN bus is a single master, multi slave module, low-speed network. Technician B says the local interconnect network (LIN) was developed to take the place of the CAN bus system. Who is correct?

The Controller Area Network (CAN) system can support baud rates up to 5 Mb/s.

What is a central gateway (CGW) module?

Each module on the Programmable Communication Interface (PCI) system supplies:

Controller Area Network (CAN) bus diagnostics is being discussed. Technician A says a scan tool is used to access the central gateway module for the bus network. Technician B says if the scan tool can communicate with the central gateway module, then the CAN C circuit is at fault. Who is correct?

What protocol is the class B standard for OBD II?

Technician A says wireless networks can connect modules together to transmit information with the use of electromagnetic field. Technician B says Bluetooth technology allows several modules from different manufacturers to be connected using a standardized radio transmission. Who is correct?

The Media Oriented System Transport (MOST) cooperation data bus system uses fiber optics to transmit data.

The local interconnect network (LIN) bus is a UART singe master, multiple slave, low-speed network.

The data transmission of the PCI bus is being discussed. Technician A says the Header detects if the message has been corrupted or if there are any other errors. Technician B says the cyclic redundancy check (CRC) is one to three bytes of information concerning the type, length, priority, target module, and sending module. Who is correct?

The Controller Area Network (CAN) was developed to supplement the local interconnect network (LIN) bus system.

Technician A says ISO 9141-2 is not a network protocol since it can be used only for diagnostic purposes. Technician B says ISO 9141-2 is a Class B system that has a baud rate of 10.4Kb/s. Who is correct?

Describe the operation and common usage of the Media-Oriented System Transport (MOST) data bus system.

What is the local interconnect network (LIN) bus?

A Controller Area Network (CAN) bus circuit consists of a pair of ____.

The __________ network has all of the modules connected to a central point.
