Abstract
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.
