Abstract: A diagnostic tool and method are provided that can determine the communication protocol being used by diagnostic systems in a vehicle. The tool can automatically communicate with onboard computer of the diagnostic system in a first communication protocol and if unsuccessful, then can communicate with the diagnostic system in a second communication protocol. The tool can also determine the Baud rate of the communication protocol being used by the onboard computer.

Abstract: A diagnostic tool with an adaptive method is provided that will adaptively change the time interval at which the tool interrogates the vehicle if the tool determines if a diagnostic test is not progressing. The tool can interrogate at that interval until it reaches the iteration limit. The tool can also restart at the previous time interval and iteration limit if the tool recognizes that it was previously communicated with the vehicle.

Abstract: Exemplary embodiments of the present invention relate generally to an improved off-board tool for communicating with a vehicle diagnostic system using a CAN communications protocol. In one exemplary embodiment, an off-board tool having an executable program for linking the off-board tool to a vehicle diagnostic system is provided. The program includes code for transmitting a first message, having a first length from the off-board tool to the vehicle diagnostic system and code for determining whether an acknowledgment receipt of the first message is received by the off-board tool from the vehicle diagnostic system. The program further includes code for transmitting a second message, having a second length, from the off-board tool to the vehicle diagnostic system if the acknowledgement receipt of the first message is not received by the off-board tool. Another exemplary embodiment provides a method for linking an off-board tool to a vehicle diagnostic system.
