Diagnostic Standards: SOVD, OBDonUDS, OBD, ODX, UDS and OTX
The development and introduction of new diagnostic concepts and diagnostic solutions offer significant potential to automotive OEMs and suppliers for realizing efficiency gains and quality improvement.
Growing complexity in automotive electronics can only be mastered – technically and economically – by use of nonproprietary standards, close cooperation and powerful tools.
SOVD
With the introduction of HPCs (High-Performance Computer) and thus increasingly software-based systems in future vehicles, diagnostics faces new challenges. With this background, the "Service-Oriented Vehicle Diagnostics" (‘SOVD’) project was launched in ASAM in 2019. The standardization aims to create a modern, simple diagnostic interface that equally enables access to classic ECUs and emerging software-based systems.
OBDonUDS
The freshly updated revision of the SAE J1979-2 standard (OBDonUDS) now requires the use of UDS (Unified Diagnostic Services) for reading out OBD diagnostic data. UDS is standardized in ISO 14229 and has been used for the extended, manufacturer-specific scope of diagnostics for many years.
OBD
The emission characteristics of vehicles are monitored by the legally prescribed on-board diagnostics (OBD). Each emission-relevant ECU must therefore support the OBD diagnostic. Therefore more and more automotive suppliers face the challenge to develop OBD-capable ECUs. Vector supports you with powerful tools and embedded software.
ODX
Vector supports ODX (Open Diagnostic Exchange format; ISO 22901-1:2008) in all diagnostic-related products, providing a simple and effective way to handle ODX diagnostic data. Since 2001, Vector is contributing to define the ODX standard in ASAM and ISO working committees.
UDS
Unified Diagnostic Service (UDS) according to the ISO 14229 standard is a protocol used by diagnostic systems to communicate with ECUs in vehicles. The protocol is used to diagnose errors and reprogram ECUs. For example, it is possible to read and delete the fault memory of an ECU or to flash a new firmware on the ECU.
OTX
OTX (Open Test Sequence eXchange) is a standardized exchange format, standardized in ISO 13209, for formally describing automated diagnostic sequences such as system tests or guided debugging.
