Modern agricultural equipment is becoming smarter… but also more complex. A warning light flashes on your Case IH tractor or harvester’s dashboard, a code appears — and suddenly you’re facing a cryptic message that only a dealer seems able to understand.
Good news: with the right tools, you can diagnose and fix these issues yourself — quickly and efficiently. This guide will walk you through what Case IH error codes mean and how to interpret them using the Jaltest INFO Web technical data platform.
đźšś Case IH: A Global Agricultural Leader
Before diving into error codes, a quick word on the brand.
Case IH is an American manufacturer of agricultural machinery, born from the merger of J.I. Case and the agricultural division of International Harvester in 1985. Now part of the CNH Industrial group, Case IH is a key player in the global farming equipment market.
Its product line includes:
- Tractors (Puma, Maxxum, Magnum, Steiger)
- Combine harvesters (Axial Flow series)
- Hay tools, sprayers, seeders, and more
Known for their durability and innovation, Case IH machines are consistently recognized for high performance.
đź§© Case IH Fault Codes: Your Diagnostic Clues
Each error code displayed on your machine is a diagnostic clue. It could point to a minor issue (e.g., unstable connection) or a critical fault (e.g., engine overheating).
There are two main types of fault codes:
- Pending Code – Early warning, not yet confirmed. May disappear if the issue doesn’t recur.
- Permanent Code – Confirmed fault that requires repair and won’t clear automatically.
Identifying these codes early lets you:
âś… Prevent major breakdowns
âś… Reduce machine downtime
âś… Avoid costly repairs
