A critical aspect of ISO 14229-1 is its . It defines different diagnostic sessions—such as the Default Session , Programming Session , and Extended Diagnostic Session —each offering varying levels of access to the ECU's internal functions. Security is often maintained through a "Seed-Key" exchange mechanism, ensuring that only authorized tools can perform sensitive operations like writing data or reflashing memory.
