FixFaults Industrial Fault Codes — Sample

A public sample (currently 2,808 — refreshed weekly from the live catalog) of the FixFaults industrial repair encyclopedia. Each row pairs a manufacturer fault code with a human-readable description and recommended repair action, ready to load for diagnostic-LLM fine-tuning, evaluation, or retrieval.

Full corpus: 70,000+ codes across 82+ manufacturers (Caterpillar, Cummins, Siemens, Fanuc, ABB, Bobcat, Haas, Yaskawa, Daikin, OBD-II, J1939 and more). This sample is CC-BY-NC for non-commercial use. For commercial / production access, see the live REST API below.

🚀 Quick start

from datasets import load_dataset
ds = load_dataset("avneetsingla/industrial-fault-codes-sample")
row = ds["train"][0]
print(row["code"], "—", row["description"][:80])
# P0001 — Fuel Volume Regulator Control Circuit/Open

# Filter by brand
cummins = ds["train"].filter(lambda r: r["brand_slug"] == "cummins")
print(len(cummins), "Cummins codes")

📊 Schema

column	type	description
code	string	The fault / error code (e.g. P0420, A.022, SPN 4364 FMI 5)
brand	string	Manufacturer / standard (e.g. Cummins, OBD-II, Siemens)
brand_slug	string	URL-safe brand identifier (lowercase, hyphenated)
description	string	Human-readable description of the fault — what is suspect
solution	string	Recommended repair / next-step diagnostic action
equipment_type	string	Equipment category (e.g. diesel, hvac, cnc, servo-drive, plc)
severity	string	Severity tier: low / medium / high / critical
permalink	string	Slug of the source article on fixfaults.com (e.g. cummins-111-fault-code-solution)
source_url	string	Canonical URL of the source article — every row has a long-form diagnostic guide

🎯 What this is useful for

• Diagnostic copilots & repair LLMs — fine-tune Mistral / Llama / Phi on (code, brand) → (description, solution) to build a chatbot that mechanics can query in natural language.
• RAG over technical docs — embed the rows and use them as ground-truth retrieval for "what does this code mean" questions, with source_url as the citation back-link.
• Severity classification — train a model to predict severity from description + solution.
• Multi-brand mapping — disambiguate similar-looking codes across brands (e.g. A.022 on Yaskawa vs ABB).
• Multilingual seed — use English descriptions as canonical seeds for translation pipelines.
