Full title and description

Road vehicles — Unified diagnostic services (UDS) — Part 6: Unified diagnostic services on K‑Line implementation (UDSonK‑Line). This part of ISO 14229 specifies how the common set of UDS diagnostic services are implemented over K‑Line (UART‑based) vehicle networks, including requirements for diagnostic communication and server memory programming for in‑vehicle servers connected to a K‑Line network.

Abstract

ISO 14229‑6:2013 defines the implementation requirements and specific restrictions for deploying Unified Diagnostic Services (UDS) on K‑Line networks (UDSonK‑Line). It references ISO 14229‑1 and ISO 14229‑2 for service definitions and ISO 14230‑1/2 for K‑Line physical and data link layer details, and focuses only on the additional requirements and adaptations needed for K‑Line implementations (e.g., transport/network interface adaptation, data link behavior and non‑volatile server memory programming).

Scope

This part of ISO 14229 provides implementation‑level requirements for using UDS over K‑Line (UDSonK‑Line). It specifies which diagnostic services are to be used over K‑Line, adaptations between ISO 14229 service definitions and the K‑Line transport/data link characteristics, and the non‑volatile server memory programming process for in‑vehicle servers communicating with external test equipment. It does not mandate an in‑vehicle K‑Line bus architecture and avoids duplicating information already given in ISO 14229‑1/2 and ISO 14230‑1/2.

Key topics and requirements

• Mapping and implementation of UDS application layer services for K‑Line networks (UDSonK‑Line).
• Presentation, session and transport layer adaptation where required to match K‑Line constraints.
• Data link layer diagnostic implementation details specific to K‑Line (DoK‑Line) behavior and timing.
• Requirements and process for server non‑volatile memory programming via K‑Line (ECU programming considerations).
• Normative references and dependencies on ISO 14229‑1, ISO 14229‑2, ISO 14230‑1 and ISO 14230‑2.
• Restrictions and implementation guidance specific to K‑Line networks (timing, frame formats, single‑wire UART considerations).

Typical use and users

Used by vehicle OEM engineering teams, Tier‑1 suppliers, diagnostic tool and scan‑tool manufacturers, automotive test and validation engineers, and certification/compliance laboratories that implement or test UDS over K‑Line. It is primarily a technical implementation reference for software and hardware developers building K‑Line diagnostic interfaces and for teams developing ECU programming and service tools.

Related standards

Closely related standards include ISO 14229‑1 (UDS specification and requirements) and ISO 14229‑2 (session layer services), plus the K‑Line diagnostic standards ISO 14230‑1 and ISO 14230‑2 (DoK‑Line physical and data link layers). Other related vehicle diagnostic and transport standards referenced in broader diagnostics contexts include ISO 15765 (CAN/ISO‑TP) family and ISO 27145 (WWH‑OBD / diagnostics for commercial vehicles); industry documents such as relevant SAE J‑series specifications may also be referenced where mapping is required.

FAQ

Q: What is this standard?

A: ISO 14229‑6:2013 is Part 6 of the ISO 14229 series and defines how Unified Diagnostic Services (UDS) are implemented over K‑Line (UART‑based) vehicle networks (UDSonK‑Line), including diagnostic message handling and ECU memory programming requirements.

Q: What does it cover?

A: It covers implementation requirements for UDS on K‑Line — mapping service behavior to K‑Line transport/data link characteristics, application/session/transport adaptations as needed, data link diagnostic rules, and the non‑volatile server memory programming process. It does not prescribe vehicle bus architecture.

Q: Who typically uses it?

A: Automotive OEMs, Tier‑1 suppliers, diagnostic tool vendors, ECU software engineers, test/validation teams and compliance laboratories working on K‑Line diagnostic implementations and ECU programming tools.

Q: Is it current or superseded?

A: As published in March 2013 (Edition 1), ISO 14229‑6 is recorded as published and was confirmed in ISO’s review cycle (stage 90.93). Users should verify the ISO catalogue for any amendments or later revisions before relying on the standard for new developments.

Q: Is it part of a series?

A: Yes — it is Part 6 of the ISO 14229 series (Unified Diagnostic Services). The series includes parts that define UDS service specifications, session layer services and other media‑specific implementation parts.

Q: What are the key keywords?

A: UDS, K‑Line, UDSonK‑Line, DoK‑Line, ECU programming, diagnostic services, vehicle diagnostics, ISO 14229, ISO 14230.
