Global Diagnostic Challenges and Solutions Including Current and Future Standards 2004-21-0012

Increasing vehicle complexity, broader vehicle variety, and global vehicle projects are a major challenge to all global vehicle manufacturers. Common vehicle projects not only require a common E/E-architecture in order to share components, but also a common diagnostic strategy. On-board and off-board strategies have been developed to achieve this goal.

This paper will explain the importance of ISO-standardization, common networking & diagnostic architectures and standardized access to vehicle electronics. Also the need for a common diagnostic process chain throughout engineering, manufacturing and service, and the need for harmonized vehicle standards between passenger cars and heavy duty trucks will be addressed.

Furthermore, this presentation will explain the diagnostics-related development cycle of an Electronic Control Unit (ECU), show updated diagnostic vehicle architectures, as well as the applicability of current and future standards to streamline on-board and off-board diagnostic development.
