odxtools is a Python library providing utilities to work with the ODX (Open Diagnostic Data eXchange) standard, primarily for automotive diagnostics. It enables parsing and internalizing ODX diagnostic database files, as well as encoding and decoding diagnostic messages for Electronic Control Units (ECUs). The library is actively maintained with frequent minor releases and occasional major version updates; the current version is 11.0.6.

This quickstart demonstrates how to load an ODX database from a .pdx file and iterate through the available ECUs and their services. It includes a placeholder for a PDX file, which you would replace with your actual diagnostic database.
Update your code to use the new, more specific loading functions such as `odxtools.load_pdx_file()` for PDX files, or `odxtools.load_odx_file()` for single ODX-D files. Refer to the latest documentation or examples on the GitHub README for the correct function to use for your file type.
Use the non-strict mode (`odxtools.exceptions.strict_mode = False`) sparingly and with caution. Always re-enable strict mode (`odxtools.exceptions.strict_mode = True`) immediately after parsing the non-conformant file to prevent unexpected behavior in subsequent operations. Ensure thorough validation of data processed in non-strict mode.
A solid understanding of ODX concepts is highly recommended before diving into the library. Leverage the examples provided in the GitHub repository and be prepared to explore the source code for deeper insights. Engage with the project's GitHub issues for community support.
Update your code to use the new loading functions like `odxtools.load_pdx_file()` for PDX files or `odxtools.load_odx_file()` for single ODX-D files, matching your ODX database type.
Temporarily enable non-strict mode by setting `odxtools.exceptions.strict_mode = False` before loading the problematic file. Remember to reset `odxtools.exceptions.strict_mode = True` after parsing to maintain strict error checking for subsequent operations.
Ensure the file path is correct, including the file name and extension. Use an absolute path or verify that the file is in the expected relative directory to your script. Always double-check typos in the file name or directory structure.
Carefully inspect the ODX database content (e.g., by using the `odxtools browse` command-line tool or by iterating through the available objects in your script) to confirm the exact short name and hierarchical path of the desired element.
Convert the data to the expected type: use `.encode('utf-8')` on a string to get bytes (e.g., `my_string.encode('utf-8')`), or `.decode('utf-8')` on bytes to get a string (e.g., `my_bytes.decode('utf-8')`), adjusting the encoding as necessary for your specific ODX messages.
