Abstract
A communications network is adapted to provide communication between control modules on a vehicle. Each control module includes a first and second transceiver. A control module checks for the presence of a data message from another control module before transmitting a data message. If there is no other data message present, the control module transmits the data message around the network in both directions using the first and second transceivers. The other control modules receive the data message from the previous control module and pass the data message to the next control module in the network.
