J1939 Data Backbone

A high-level protocol used in heavy-duty vehicles for networking and communication among vehicle components over a CAN bus.

Terminating Resistor

Used to prevent the twisted-wire pair used in a data bus from attracting signal interference by acting like a giant antenna. A current data bus uses two terminating resistors that test at 120 ohms. If one is missing, the data bus may function erratically, but if both are missing, no effective networking can take place.

J1939 Data Backbone

A part of the J1939 standard providing a means for the integration of various vehicle components over a common network, allowing them to communicate information.

Twisted Wire Pair

A type of wiring where two conductors are twisted together to cancel out electromagnetic interference and improve communication reliability.
