Full title and description

St ISO 13400-2-2019 amd1-2023 — Road vehicles — Diagnostic communication over Internet Protocol (DoIP) — Part 2: Transport protocol and network layer services — Amendment 1 (amendment to ISO 13400-2:2019). This document provides amendments and clarifications to the transport-protocol and network-layer service definitions used for DoIP-based vehicle diagnostic communication.

Abstract

This amendment updates and clarifies aspects of Part 2 of the DoIP family (transport protocol and network layer services). It modifies normative text in ISO 13400-2:2019 to address interoperability, message formats, addressing and transport-layer behaviour; the amendment was published in 2023 and has since been withdrawn and incorporated into the consolidated ISO 13400-2:2025 edition.

Scope

This amendment applies specifically to Part 2 of the DoIP series (ISO 13400-2:2019). It amends transport‑layer and network‑layer specifications for diagnostic communications over IP in road vehicles — for example, clarifying transport protocol behaviour (TCP/UDP handling), addressing and discovery mechanisms, message/framing details and timing/retransmission rules that affect client (test equipment) and vehicle gateway interoperability. Note: the consolidated and updated rules are included in the 2025 edition of ISO 13400-2.

Key topics and requirements

• Clarifications to DoIP transport‑protocol message formats and sequence handling.
• Network-layer addressing and discovery behavior for vehicle gateways and DoIP entities.
• Timing, retransmission and error-handling expectations for transport-layer exchanges.
• Interoperability notes for client (test equipment) and server (vehicle/gateway) implementations.
• Normative amendments intended to be incorporated into the consolidated 2025 edition of ISO 13400‑2.

Typical use and users

Used by vehicle OEMs, tier‑1 and tier‑2 suppliers, diagnostic tool and test‑equipment manufacturers, automotive network and embedded‑software engineers, test laboratories and conformity assessors. The amendment is relevant for implementers who need to align DoIP transport and network behavior with the consolidated 2025 edition or maintain compatibility with vehicles implementing the 2019/2023 texts.

Related standards

Part of the ISO 13400 DoIP family (see ISO 13400-1 and ISO 13400-3 for general use cases and the wired vehicle interface). ISO 13400-2 (2025) consolidates earlier editions and amendments. Other related automotive diagnostic standards commonly used alongside DoIP include ISO 14229 (UDS) for diagnostic services.

FAQ

Q: What is this standard?

A: It is ISO 13400-2:2019/Amd 1:2023 — an amendment to Part 2 of the DoIP family that updates transport‑protocol and network‑layer service definitions for diagnostic communication over IP in road vehicles.

Q: What does it cover?

A: It covers amendments and clarifications to transport‑layer and network‑layer behaviours (message formats, addressing/discovery, timing/retransmission and interoperability notes) for DoIP implementations. The consolidated requirements are now contained in ISO 13400-2:2025.

Q: Who typically uses it?

A: Automotive OEMs, diagnostic tool vendors, tier suppliers, software/firmware engineers, and test laboratories that implement or verify DoIP transport‑ and network‑layer behaviour.

Q: Is it current or superseded?

A: The 2023 amendment was published in July 2023 but has been withdrawn and superseded by the consolidated ISO 13400-2:2025 edition; implementers should reference the 2025 edition for the current text.

Q: Is it part of a series?

A: Yes — ISO 13400 is a multi‑part series for DoIP (for example Part 1: general information and use cases; Part 2: transport and network layer services; Part 3: wired vehicle interface); this amendment applied to Part 2:2019.

Q: What are the key keywords?

A: DoIP, transport protocol, network layer, diagnostic communication, vehicle gateway, ISO 13400, amendment, TCP, UDP, interoperability.
