I notice you’re asking about — 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).
ISO 14229-3:2016 is a standard developed by the International Organization for Standardization (ISO) that specifies the requirements for diagnostic communication over Controller Area Network (CAN) in road vehicles. The standard is divided into several parts, with Part 3 focusing on the data link layer and application layer. The ISO 14229-3:2016 PDF provides a detailed overview of the protocol and its implementation.
Requests Diagnostic Trouble Codes (DTCs) from the ECU to pinpoint electrical or mechanical faults.
UDS is the automotive protocol that enables diagnostic systems to communicate with electronic control units (ECUs) to diagnose faults, reprogram ECUs, and perform routine testing.
Each country has its own NSB that resells ISO standards, often in local currency and with local support. The most prominent ones include: iso 142293 pdf

ISO 14229-2 (Manages network timing and session parameters).
It ensures that diagnostic tools (testers) and Electronic Control Units (ECUs) from different manufacturers can communicate seamlessly over a CAN network. The standard is divided into several parts, with
The standard specifies the use of both 11-bit (standard) and 29-bit (extended) CAN identifiers for diagnostic communication.
Diagnostics require strict timing to prevent communication timeouts or network hogs. The standard references and clarifies timing parameters, such as:
It serves as the bridge between the (the diagnostic request/response) and the Data Link/Physical Layers (the CAN frame). Key Features of UDSonCAN:
The 2012 edition has been officially withdrawn and replaced by the 2022 edition.
It specifies how the diagnostic services defined in ISO 14229-1 are mapped to the bus, as standardized by ISO 11898 . This means it defines how UDS messages are packaged, transmitted, and received across the CAN network. Key Aspects of ISO 14229-3:
