    Understanding ISO 14229-3: Unified Diagnostic Services on CAN (UDSonCAN)

    ISO 14229-3 is a critical international standard for the automotive industry, defining how Unified Diagnostic Services (UDS) are implemented specifically over the Controller Area Network (CAN). Often referred to as UDSonCAN, this part of the ISO 14229 series ensures that diagnostic tools can communicate seamlessly with a vehicle's Electronic Control Units (ECUs) to detect faults, update firmware, and perform routine testing.

    The current version, ISO 14229-3:2022, was released in March 2022 to replace the original 2012 edition. Core Purpose and Scope

    While ISO 14229-1 defines the general diagnostic services, ISO 14229-3 provides the specific application profile for CAN-based systems.

    Implementation Requirements: It specifies how the session, presentation, and application layers of the OSI model map to CAN communication.

    Specific Restrictions: The standard outlines additional requirements or restrictions that only apply when UDS is used over CAN, rather than Ethernet or FlexRay.

    Bridge to Hardware: It references ISO 15765-2 for the transport protocol and ISO 11898-1 for the physical data link layer. Key Services with CAN-Specific Requirements

    While most UDS services follow the general rules of ISO 14229-1, a few have unique requirements when implemented on CAN:

    ResponseOnEvent (0x86): Specific CAN-based handling is required for events that trigger diagnostic responses.

    ReadDataByPeriodicIdentifier (0x2A): Implementation details vary for periodic data transmission over the restricted bandwidth of a CAN bus. The OSI Model Structure in ISO 14229-3

    ISO 14229-3 structures communication into the following layers to ensure global interoperability: ISO 14229-3:2022 - Unified diagnostic services (UDS)

    ISO 14229-3:2022 - Road vehicles — Unified diagnostic services (UDS) — Part 3: Unified diagnostic services on CAN implementation ( ISO - International Organization for Standardization ISO 14229-3:2022(en), Road vehicles

    I notice you’re asking about ISO 142293 — but please double-check that number. ISO standards typically follow a 5-digit format (e.g., ISO 14223), and 142293 exceeds the usual range (most are 1–99999).

    It’s likely a typo. You probably meant one of these:

    • ISO 14223 — Radiofrequency identification of animals (transponders)
    • ISO 14229 — Unified Diagnostic Services (UDS) for automotive (very common)
    • ISO 14253 — Geometrical product specifications (GPS)

    If you can confirm the correct standard number, I’ll gladly help you develop a post (e.g., summary, key takeaways, application guide, or implementation checklist) based on its content.

    To clarify: I cannot provide or link to the PDF itself due to copyright, but I can help you summarize, explain, or create derivative content once you confirm the right ISO number and tell me your target audience (engineers, students, quality team, etc.).

    Why "ISO 142293" May Be a Typo or Misreference

    The ISO (International Organization for Standardization) numbering system follows a logical sequence. Common numbers in the 14000 series relate to environmental management (ISO 14001). The number 142293 falls outside typical ranges. Based on extensive database searches (ISO.org, ANSI, BSI), there is no published standard titled ISO 142293.
