UDS

The Raptor UDS Blockset provides a Raptor application with an interface to a PC-based diagnostics application or a scan tool. Raptor UDS covers both the On-Board Diagnostics (ISO 15031-5) and the Unified Diagnostic Services (ISO 14229) and uses the ISO 15765 specification for the CAN transport layer.

UDS is a way to provide the Raptor application with the capability of reporting self-diagnostics and trending information. The Raptor UDS Blockset does not provide diagnostics. The diagnostics must be provided by the application designer and then integrate the blockset with their diagnostic capabilities and the mechanism for reporting the diagnostic information via a standardized protocol.

The UDS handler mask informs the application that the ISO 15031 and ISO 14229 services are desired.

The UDS blockset can be used to provide the following services:

• Diagnostic Trouble Codes (DTC) reporting/clearing
• Suspension of DTC logging
• Emissions
• Parameter reading/writing
• Overrides
• On-demand self-tests
• Snapshot records
• Module reflashing (requires bootloader support)

New Eagle Support for Unified Diagnostic Service (UDS)

• ISO blockset to create UDS server that interfaces with PC-based diagnostic application or scan tool
• ISO blockset to create UDS client to query UDS servers for information
• Provides select ISO 14229-1 Unified Diagnostic (UDS) and ISO 15031 On-Board Diagnostics (OBD) services
• Provides the application with the capability of reporting self-diagnostics and trending information
• Integration service is included in the sale of the UDS blockset

Licensing for UDS Client

UDS Client functionality does not include specific support for services. It contains the ability to construct specific queries and then read the responses using the underlying CAN messages.
