Case IH Fault Codes Lookup
Search Case IH fault codes by code number, machine family, or system. Use the lookup to narrow a warning to the engine, transmission, hydraulics, electronics, or another monitored component before moving to the correct service information.
Find a fault code
Enter the number shown on the display and choose the relevant machine system.
Fault code information for Case IH machines
The same number can refer to different systems on different machines. Start with the equipment category to keep the results relevant.
Case IH tractor fault codes
Diagnostic references for Magnum, Puma, Maxxum, Steiger, Quadtrac, MX, STX, Farmall, and other tractor ranges.
Combine fault codes
Look up warnings and diagnostic codes found on harvesting equipment, including commonly searched 7088 and related combine models.
Planter fault codes
Find monitor, control, sensor, and row-unit related information for equipment such as the Case IH 1200 planter family.
Engine fault codes
Search engine controller, fuel delivery, temperature, pressure, emissions, and sensor-related diagnostic codes.
Transmission fault codes
Decode powershift, CVT, clutch, speed sensor, pressure, controller, and driveline warnings across supported models.
Electrical and control systems
Use system filtering for controller communication, voltage, display, CAN bus, sensor, and electronic module issues.
Browse popular Case IH models
These model families appear often in fault-code searches and provide a practical structure for model-specific diagnostic pages.

Magnum
Magnum 180, 210, 290, 305, 340, 380, and related diagnostic references.
Maxxum
Maxxum and Maxxum 125 fault codes organized by monitored system.
Steiger & Quadtrac
Engine, transmission, driveline, and electronic control warnings.
MX Series
MX200, MX255, MX270, and other frequently searched MX models.
STX Series
STX transmission fault codes and related tractor diagnostics.
7088 Combine
Combine-specific warning codes and monitored harvesting systems.
1200 Planter
Planter control, monitoring, sensor, and electrical fault references.
Identify where the warning originates
A diagnostic number is most useful when it is paired with the correct controller and machine system. The lookup can be organized around the systems operators most often need to check.
- Engine: fuel, air, cooling, pressure, temperature, emissions, and engine control signals.
- Transmission: clutch packs, speed sensing, pressure, gear selection, powershift, and CVT functions.
- Hydraulics: remotes, hitch, pump pressure, valve control, and hydraulic sensors.
- Electrical: power supply, wiring, CAN communication, displays, switches, and electronic modules.
- Implement control: planter, ISOBUS, monitor, section, and machine-specific control faults.

How to use the fault code lookup
The lookup is designed to help you reach the right reference faster, not to replace the official service procedure.
Record the complete code
Copy every digit and any prefix, controller name, symbol, or message shown on the display.
Select machine and system
Choose the tractor, combine, planter, engine, transmission, or other relevant category.
Review the correct procedure
Confirm the meaning against the proper operator or service manual before testing or replacing parts.
Case IH machines and onboard diagnostics
Case IH equipment includes tractors, combines, planting systems, and other agricultural machines that use electronic controllers to monitor engine, transmission, hydraulic, electrical, and implement functions. When a controller detects a value outside its expected range, the operator display may show a diagnostic or fault code.
This independent resource is structured to make those codes easier to find by number, model family, machine type, and system. It can support the first stage of troubleshooting by helping operators and technicians identify the most relevant documentation.
The final diagnosis should always consider the complete machine configuration, active and stored codes, operating conditions, connector condition, wiring, software level, and the official service procedure.
