The Media Oriented System Transport (MOST) cooperation data bus system uses fiber optics to
transmit data. T or F
True
Wireless networks require the use of one wire to transmit information. T or F
False
The Controller Area Network (CAN) system can support baud rates up to 5 Mb/s. T or F
True
The ISO-K bus protocol allows for bidirectional communication on a single wire. T or F
True
, Technician A says J1850 protocol is the class B standard for OBD II. Technician B says the J1850
standard allows for four different versions based on baud rate. Who is correct?
A
Bluetooth technology allows several modules from different manufacturers to be connected
using a standard high definition transmission. T or F
False
Multiplexing (MUX) networks allow several devices to share signals on a common conductor. T
or F
True
Each computer is connected to the data bus is called a mole. T or F
False
Multiplexing (MUX) wiring systems use bus data links that connect modules together. T or F
True
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?
