Scope

This document specifies a minimum set of diagnostic Ethernet connector requirements
which are based on ISO 15031-3.
The diagnostic connection specified in this document consists of two mating connectors:
the vehicle connector and the external test equipment connector as specified in ISO
15031-3.
This document specifies:
— the functional requirements for the vehicle connector. These functional
requirements are separated into two principal areas: connector contact allocation
and electrical requirements for connector and related electrical circuits;
— the functional requirements for the external test equipment connector. These
functional requirements are separated into two principal areas: connector contact
allocation and electrical requirements for connector and related electrical circuits.
Two different connector layouts and pin-outs are specified in this document:
— Ethernet pin assignment option 1;
— Ethernet pin assignment option 2.
Historically, option 1 is specified to meet Ethernet pin assignment of road vehicles
already launched onto the market and may be used to resolve conflicts with vehicle
manufacturer-specific usage of discretionary pins, e.g. pins 1 and 9.
Option 2 is specified to meet the Ethernet pin assignment of road vehicles to resolve
conflicts with vehicle manufacturer-specific usage of discretionary pins, e.g. pins 3 and
11.
A discovery/identification and activation method of the vehicle’s Ethernet via the
“Ethernet Activation Line” is specified in ISO 13400-3.
This document applies to the design and use based on 100BASE-TX diagnostic
Ethernet connector.
