Abstract: Disclosed are methods and devices related to diagnosing a device-under-service (DUS) are disclosed. DUS-related data is received. The DUS-related data is determined to be aggregated into aggregated data based on a determined classification of the DUS-related data. An aggregated-data comparison of the DUS-related data and aggregated data is generated. The aggregated-data comparison can include a statistical analysis of the DUS-related data and/or a differential analysis of DUS-related data taken while the DUS is operating in two or more operating states. A DUS report is generated based on the aggregated-data comparison. The DUS report can include one or more sub-strategies. At least one of the one or more sub-strategies can include a sub-strategy-success estimate. The DUS report can be sent and a DUS-report display can be generated based on the DUS report.

Abstract: A programmable vehicle or engine diagnostic tool includes an interface for receiving a signal relating to a performance parameter of the vehicle or engine, a user interface, and a central processing unit, for processing the signal to generate information for presentation to the user. The system utilizes a fast access non-volatile random access type main memory to store the programming for execution by the central processing unit. Techniques are disclosed for moving applications to the main memory, for fast boot at subsequent operation, based for example on program usage or user selection.

Abstract: A method and system diagnosing vehicle faults using a diagnostic tool capable of communicating with a remote host. Diagnostic data, vehicle data, and a diagnostic routine are stored in data storage of a diagnostic tool. The diagnostic data defines vehicle fault descriptions, corresponding vehicle fault symptoms, and corresponding repair instructions, and the vehicle data defines vehicle operation information. The diagnostic tool is capable of communicating with a remote host that can diagnose vehicle faults using the vehicle data, and send diagnosis information, including a diagnosis and repair instructions to the diagnostic tool. In response to receiving diagnosis information from the remote host, the diagnostic tool displays the information to a user. Advantageously, the system and method can allow the diagnostic tool access to additional computing power and external databases for diagnosing vehicle faults.
