Network Termination
The Controller Area Network (CAN) uses a network termination circuit to improve communication reliability. The network termination of the CAN bus
takes place inside the termination modules by termination resistors. Termination modules are located at either end of the bus network. As network
messages are broadcast in the form of voltage signals, the network voltage signals are stabilized by the termination resistors. Each termination module
has a 120 ohm resistor across the positive and negative bus connection in the termination module. With 2 termination modules on each network, and the
120 ohm resistors located in a parallel circuit configuration, the total network impedance, or total resistance is 60 ohms.
Network termination improves bus message reliability by:
-
Stabilizing bus voltage
-
Eliminating electrical interference
Gateway Module
The Instrument Cluster (IC) is the gateway module, translating HS-CAN to MS-CAN and vice versa. This information allows a message to be distributed
throughout both networks. The IC is the only module on this vehicle that has this ability.
