Objectives

The participant:

• Gets advanced knowledge to develop offboard and onboard diagnostics.
• Among other things, learns how to model diagnostic services based on ISO 14229-1 (UDS), data interpretation based on ISO 22901-1 as input for SGBD and ODX, and how to develop a basic understanding of how to configure the AUTOSAR stack (via DEXT) for ECU software.
• The topics covered are fundamental for the ISO-compliant specification in ZEDIS and serve as an indispensable basis for ensuring quality for the securing areas.
