1. A method comprising:
- wirelessly communicating a first onboard message from a first communication device onboard a first vehicle to a second communication device that also is onboard the first vehicle, the first communication device and the second communication device configured to wirelessly communicate with one or more other communication devices disposed onboard one or more second vehicles in a vehicle system that includes the first vehicle and the one or more second vehicles for remote control of at least one of the first vehicle or the one or more second vehicles;
determining receipt of the first onboard message at the second communication device;
wirelessly communicating a second onboard message from the second communication device to the first communication device;
determining receipt of the second onboard message at the first communication device; and
determining a first operative state of the first communication device and a second operative state of the second communication device of the first vehicle based at least in part on the receipt of the first onboard message at the second communication device and the receipt of the second onboard message at the first communication device,wherein the first operative state of the first communication device and the second operative state of the second communication device indicate closure of a switch conductively coupled with the first communication device and the second communication device, or indicate opening of the switch conductively decoupled with the first communication device and the second communication device;
wherein the closure of the switch corresponds to an occurrence of a communication fault and the opening of the switch corresponds to a non-occurrence of the communication fault.

Abstract
Communication methods and systems wirelessly communicate onboard messages between communication devices onboard the same vehicle. The communication devices can wirelessly communicate with other communication devices onboard other vehicles in a vehicle system for remote control of the vehicles. Receipt of the onboard messages at the communication devices is determined, and operative states of the communication devices are determined based at least in part on the receipt of the onboard messages at the communication devices. Determining these operative states in this manner can allow for an operator to identify communication faults with the communication devices prior to departing the vehicle.
