Wireless interface adaptor for remote diagnosis and programming of vehicle control systems
First Claim
1. A diagnostic system for a changeable selection of motor vehicle electrical control systems, where each motor vehicle electrical control system includes a data bus, an electrical system controller connected to the data bus and a standard diagnostic port connected to the bus, the diagnostic system comprising:
- a base programming and evaluation station;
a first wireless communication interface connected to the base programming and evaluation station; and
a transferable node including a bi-directional data staging interface connectable to a diagnostic port for a vehicle electrical control system; and
a second wireless communication interface connected to the data staging interface.

Abstract
An apparatus and a method of evaluating vehicle electrical control systems implements a base evaluation and programming station by an appropriately programmed portable computer. A wireless network communication interface is connected to the base evaluation and programming station. Vehicles may then be brought into the general vicinity of the base station. The electrical control system for each vehicle brought into range for testing may be temporarily attached to a transferable wireless node including a wireless communication interface and two way data staging element. Thereupon an ad hoc network is established with individual communication links between the wireless communication interface connected to the base evaluation and programming station and each transferable wireless communication interface.
