Field notes
The homepage organizes diagnostic references by equipment category and then by brand, with visible counts for each collection. CNC accounts for 5,836 listed codes and OBD-II for 4,960, while smaller sections cover areas such as textile machinery, welding, air dryers, and SCADA. The page states that individual records include meanings, causes, reset procedures, and troubleshooting guidance, although no record detail is visible in the supplied extract.
