Wheel Chair Repair Service is a method and apparatus for the remote maintenance, troubleshooting and repair of electric or motorized wheelchairs. A wheelchair diagnostic system includes a data communications network, a motorized wheelchair having a controller associated therewith, a modem coupled between the controller and the data communications network, a remote data processing unit coupled to the data communications network and a diagnostics tool executing on the remote data processing unit which facilitates communicating with the controller across the data communications network. The diagnostics tool includes computer readable code which causes data from the controller to be downloaded across the data communications network to the remote data processing unit so that a service technician can view error code and drive parameter data for troubleshooting, diagnosing and/or repairing the wheelchair.
