1 Scope
This part of ISO 13400 specifies the vehicle communication interface and test equipment requirements for
a physical and data link layer based on IEEE 802.3 100BaseTx.
This interface serves as the physical basis for IP-based communication between the
vehicle and test equipment. This part of ISO 13400 specifies the following aspects:
-
— requirements for signal and wiring schematics in order to ensure physical layer compatibility of the vehicle interface and Ethernet networks and test equipment communication interfaces;
-
— activation and deactivation of the diagnostic Ethernet interface;
-
— mechanical and electrical diagnostic connector requirements.
