Whenever an operator attempts to access specific submenus inside DAS, the program generates an electronic seed request based on the vehicle's unique . To proceed, the operator must input an encrypted alpha-numerical response: the TAN Code .
The algorithm processes the data and outputs a specific code.
Usually a standalone .exe file or an integrated "patch" within the diagnostic software. A Note on Safety and Legality
