Abstract: Exemplary embodiments of off-board tools (OBTs) may be used in vehicle inspection maintenance programs are provided. The OBT may include a processor, vehicle communication circuitry for linking to a vehicle diagnostic system, host interface circuitry for communicating with a host computer, and voltage determination circuitry for measuring a voltage through the vehicle diagnostic system. The OBT may include logic for storing a communications protocol used to link with a vehicle diagnostic system that is preferably used for re-establishing dropped communications links. In addition, the OBT may contain logic for testing at least one component of a starting and/or charging system of a vehicle. Still other embodiments may include logic for sending unsolicited messages to a host computer. Additional embodiments may include logic for determining the minimum number of messages that must be received by an OBT.

Abstract: A diagnostic tool for a vehicle, includes a signal translator communicating with the vehicle in at least one protocol, an input unit for inputting information, a processor controlling a software according to the input information and communication with the vehicle, the processor controlling a recording of diagnostic data of the vehicle through the signal translator, a memory storing a software including a database controlled by the processor, the memory storing baseline data of the vehicle and recorded diagnostic data in the database, the processor comparing the stored baseline data and recorded diagnostic data, and a display unit displaying information according to the comparison between the stored baseline data and recorded diagnostic data. The comparison can also be made on a separate computer storing the baseline data and receiving the recorded data from the diagnostic tool.

Abstract: A programmable actuator having multiple programmable functions is provided. The programmable actuator may be used on an off-board tool. In accordance with an embodiment, an off-board tool, OBT, including a user-defined programmable actuator is provided. In accordance with another embodiment, an OBT includes a processor, an internal memory, a programmable actuator, program logic and perform function logic.

Abstract: An improved scan tool, e.g., for OBD II, for use with vehicle computer networks. The improved scan tool determines the proper protocol to use to communicate with a vehicle computer network. The proper protocol is determined by requesting information from the vehicle computer network using a plurality of protocols and selecting the protocol that returns the most pieces of information. In addition, the improved scan tool determines a communications drop-out with one or more modules and automatically recovers from the communications drop-out.
