摘要： A system and method for demonstrating or testing operation of on-board diagnostics in a vehicle include imitating performance degradation of a vehicle hardware component and/or associated vehicle system by dynamically modifying at least one control system parameter value associated with the hardware component in response to a request to demonstrate operation of a selected diagnostic function or a specified performance degradation. Embodiments modify at least one control system parameter value associated with the input/output signal of a sensor/actuator to imitate a specified performance degradation. The diagnostics independently monitor operation of various vehicle control systems and operate to detect the degraded performance without knowledge of, or distinguishing between, whether the performance degradation was caused by an actual hardware component, or by the requested modification to the control system parameter value(s) associated with a particular hardware component.

摘要： A system and method for retrieving and displaying data from an onboard memory of an electronic control unit in a vehicle is disclosed. The electronic control unit includes at least one parameter identifier that defines an address for a first data structure. The first data structure includes information on the amount and location of the data in the nonvolatile memory, as well as a version document number corresponding to a version document stored in a scan tool. The scan tool can access the parameter identifier and onboard data by the entry of an identifier number. The retrieved data is inserted into the version document for display.
