link connector
1 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.

5 Connector requirements
5.1 General
Vehicle manufacturers of road vehicles have the choice to implement one of two different Ethernet connector layouts and pin assignments. This is needed to meet the in- vehicle electrical architecture design.
Discovery/identification of the vehicle’s Ethernet option (configuration) is a requirement for external test equipment in order to properly connect to the Ethernet without causing any damage either to the vehicles or external test equipment bus circuitry. In addition, any bus interference like bus errors shall be avoided. The solution for external test equipment to identify the vehicle’s Ethernet option is based on reading the vehicle’s identification signal provided on the “Ethernet activation line” available on the diagnostic connector prior to enabling the multiplexer switches to establish an electrical Ethernet connection to the vehicle’s Ethernet. 5.2 Normative references to ISO 15031-3
This document specifies additional requirements to support ISO 13400-2, and ISO 13400-3 to be implemented when accessed through the ISO 15031-3 diagnostic connector.
5.3 Ethernet specific requirements
The Ethernet connector layout, pin assignment information, and simplified test equipment circuitry example for Ethernet option 1 is specified in Annex A. The Ethernet connector layout, pin assignment information, and simplified test equipment circuitry example for Ethernet option 2 is specified in Annex B.
