Retrieving fault codes from memory.
ISO 14229-3 (UDSonCAN) is a fundamental pillar of automotive diagnostic engineering. By standardizing the way diagnostic services are handled over CAN networks, it facilitates safer, more efficient vehicle maintenance and development. For developers and engineers, mastering this standard is essential to ensure that their systems are interoperable, robust, and compliant with international industry standards.
Structured by ISO 15765-2 (Diagnostic communication over CAN - DoCAN).
The ISO 14229-3 standard specifies the following technical requirements: iso 142293 pdf
ISO 14229 is a multi-part standard maintained by the International Organization for Standardization (ISO). It specifies the Unified Diagnostic Services (UDS) framework. While Part 1 (ISO 14229-1) outlines the application layer services independent of the underlying network, serves as the implementation guide specifically for CAN networks (UDSonCAN).

If you are working on a specific implementation, let me know what or hardware platform you are using. I can provide targeted code examples or troubleshooting steps for common communication timeouts. Share public link
Switches the ECU between default, programming, or extended diagnostic sessions. Retrieving fault codes from memory
ISO 14229-3 specifies the requirements for the diagnostic communication over Controller Area Network (DoCAN) protocol, which is used for vehicle diagnostics. The standard defines the data link layer and application layer of the protocol.
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.
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). For developers and engineers, mastering this standard is
Accessing and modifying specific parameter IDs (PIDs).
In modern automotive engineering, electronic control units (ECUs) govern everything from powertrain systems to advanced driver-assistance systems (ADAS). Diagnosing these complex networks requires a standardized, reliable communication protocol.
