Flow control (FC) mechanism
A common service primitive interface is specified between OSI layer 4 (Transport)
and layer 5 (Session) via the so-called service request/confirmation/indication primi-
tives. This interface allows seamless implementation of ISO°14229-1 UDSs with
any communication protocol titled “DoXYZ/CoXYZ” like ISO°15765 DoCAN—
diagnostic communication over controller area network, ISO°13400 DoIP—diag-
nostic communication over Internet protocol, ISO°10681 CoFlexRay—communica-
tion over FlexRay, ISO°14230 DoK-Line—diagnostic communication over K-line.
ISO 14229-3 UDSonCAN is based on a common document template for UDS
implementations on a specific protocol like ISO 15765 DoCAN. This specific part
of ISO 14229 specifies implementation requirements related to the following:
• The diagnostic services to be used for diagnostic communication over CAN.
• The server memory programming for all in-vehicle servers connected to a CAN
network with an external test equipment.
