Unified Diagnostic Services (UDS) is a diagnostic communication protocol used in electronic control units (ECUs) within automotive electronics, which is specified in the ISO 14229-1. [1] It is derived from ISO 14230-3 and the now obsolete ISO 15765-3 (Diagnostic Communication over Controller Area Network (DoCAN) [2]). 'Unified' in this context ...
CANape also enables symbolic access to data and functions accessible via the diagnostic protocol, and it supports calibration over XCP on FlexRay. [ 2 ] Options extend the functional features of CANape [ 8 ] by enabling access to models at runtime in Simulink , functional bypassing, optical verification of object detection algorithms in ...

The most common application for ISO-TP is the transfer of diagnostic messages with OBD-2 equipped vehicles using KWP2000 and UDS, but is used broadly in other application-specific CAN implementations where one might need to send messages longer than what the CAN protocol physical layer allows (8 bytes for CAN, 64 bytes for CAN-FD, and 2048 ...
As defined in ISO 15765-4, emissions protocols (including OBD-II, EOBD, UDS, etc.) use the ISO-TP transport layer (ISO 15765-2). All CAN frames sent using ISO-TP use a data length of 8 bytes (and DLC of 8). It is recommended to pad the unused data bytes with 0xCC. The PID query and response occurs on the vehicle's CAN bus.
But a new study suggests this standard protocol might not be necessary for a common form of early-stage breast cancer. Ductal carcinoma in situ, or DCIS, accounts for up to 25% of diagnosed breast ...
SAE J1939 defines five layers in the seven-layer OSI network model, and this includes the Controller Area Network (CAN) ISO 11898 specification (using only the 29-bit/"extended" identifier) for the physical and data-link layers. Under J1939/11 and J1939/15, the data rate is specified as 250 kbit/s, with J1939/14 specifying 500 kbit/s.
