Abstract: An apparatus and method are provided and include a formula server having formulas and conversion modules that are separate from a diagnostic application of a diagnostic tool. The diagnostic tool receives the diagnostic data and transmits it to a remote computer, where the data is converted using a formula. The resulting data is then transmitted back to the diagnostic tool for display.

Abstract: A vehicle diagnostic tool that is configured to perform one or more diagnostic tests on one or more systems of a vehicle. Once the test has been performed and data collected, the data may be forwarded to a location outside of the diagnostic tool through a mobile broadband connection device that is inserted into the diagnostic tool through a designated port. Also, a method of performing a vehicle diagnostic test utilizing such a diagnostic tool.

Abstract: An apparatus and method is provided that allows a user to record events in a vehicle via a vehicle data recorder in the latest communication protocols, such as Controller Area Network. The vehicle data recorder can record data from the event when a trigger button is actuated by the user and the CAN communication can be controlled by the CAN controller. After the data is recorded, it can transferred to a host workstation, where the user can analyze the data from the event and diagnose the problem causing the event.

Abstract: A vehicle diagnostic data collector/analyzer compiles historical vehicle diagnostic data, including measured operating parameters from a number of different vehicles operating under a variety of normal vehicle operating conditions and vehicle component failure conditions, and performs statistical analyses on various vehicle type/operating condition combinations to establish operating parameter ranges corresponding to normal operating conditions and various failure conditions. The diagnostic data collector/analyzer also measures real-time operating parameters on specific test-subject vehicles and evaluates similarities and differences between the measured operating parameters and the established ranges, and correlates the test data with known operating conditions in order to diagnose potential failure modes of vehicle components.

Abstract: A diagnostic system that includes a vehicle communication interface (VCI) and a diagnostic tool is provided. When the VCI and the diagnostic tool are coupled together through a wired connection, the VCI and the diagnostic tool can communicate with each other and provide power, as needed, to each other. The VCI and the diagnostic tool can also communicate with each other wirelessly when the are not directly coupled to each other. The VCI and the diagnostic tool are configured so that communication is uninterrupted when going from the wired connection to the wireless connection and vice versa.

Abstract: A graphical user interface for a portable diagnostic device includes a first window area in which a navigation bar is displayed, a second window area in which data list items are displayed and a wheel menu, selectively overlaying at least a portion of the first and second window areas, in which menu items are displayed. The data list items are selected in response to commands received from a first scroll ring input device, while the menu items are selected in response to commands received from a second scroll ring input device.

Abstract: A power balancing system includes a vehicle communication device connected to a data link connector of a vehicle, and a scan tool connected to the vehicle communication device, the scan tool including a handset and a vehicle connector interface (VCI), wherein power can be received from one or more of an external power source being external from the VCI, the vehicle, and an internal power supply of the scan tool, and wherein the system balances the received power.

Abstract: Exemplary embodiments of an improved scanning tool are disclosed. In various embodiments, the improved scanning tool uses at least one input capable of providing an indication of a desired operating mode of use; and an electronic control system configured to sense the desired operating mode indication, then select one of a plurality of operating system modes based on the desired operating mode indication.

Abstract: A vehicle diagnostic system couples a vehicle diagnostic tool, a remote processor, and a remote display device and provides the necessary functionality for compression, transmission, decompression and display of vehicle diagnostic data. Vehicle diagnostic data is received from a vehicle onboard computer and converted into display data, which is compressed and transmitted to the remote processor. The remote processor decompresses the vehicle diagnostic display data and displays it on the remote display device.
