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. The method includes transmitting a first message, having a first ID length including a first predetermined number of bits, from the off-board tool to the vehicle diagnostic system and determining whether an acknowledgment receipt of the first message is received by the off-board tool from the vehicle diagnostic system. The method further includes transmitting a second message, having a second ID length including a second predetermined number of bits, 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.
