Operating Case IH equipment that displays fault codes can be annoying. Case IH fault codes typically appear when your tractor has problems that need to be addressed.
But even after solving the underlying problem, your equipment might continue displaying the fault codes. Sometimes, the electronic control unit in Case IH machines can malfunction and show various fault codes. In that Case, you should clear these codes to resolve the problem.
Read on as we detail how to clear Case IH fault codes in different ways. If the Case fault codes keep reappearing, you’ll also learn what you can do to fix the problem.
What Is a Case Fault Code?
A Case IH fault code is a set of letters and numbers indicating the nature of a problem in Case IH tractors and farm equipment. The code appears on the display with a flashing light to warn the operator that the machine has an issue that needs fixing.
Fault codes in your Case equipment might indicate an issue with the engine, transmission, hitch, armrest, and more.
In most cases, erasing Case IH codes resolves the problems. However, clearing the codes doesn’t address the root cause of the issue.
Before we discuss how to fix the underlying problems, let’s see how you can clear these codes.
How to Clear Case Fault Codes
There are several methods of clearing fault codes depending on the type of equipment. However, you can use these reliable methods to remove the codes in all Case IH farm equipment.
Turn the Engine On and Off
This is the first method Case IH owners use to clear fault codes. Follow these steps and see whether you’ll erase the codes:
- Turn the Case IH engine on and allow it to warm up.
- Turn the engine off and allow it to rest for around 15-20 minutes.
- Turn the engine on again and check if this method clears the fault codes. If the codes reappear, use the method below.
Disconnect the Battery
Disconnecting the battery is one of the most common methods of clearing Case IH fault codes. Following these can help remove any fault codes that appear frequently:
- Disconnect the negative terminal: Before disconnecting your battery, turn off the engine and locate the negative terminal. This terminal has a minus (-) sign or can be black colored. Disengage this terminal from the battery.
- Clear the remaining voltage: The capacitor has some voltage despite disconnecting the terminal from your battery. Use your machine’s lights to clear the remaining capacitor voltage.
- Allow the machine to rest: You can wait 20-25 minutes for your Case IH to clear the error codes.
- Reconnect the negative terminal: Engage the negative terminal and turn on the engine. Check if this method cleared the fault codes. If the codes return, use the procedure below.
Turn the Ignition Switch On and Off
Playing with the ignition switch by turning it on and off several times can help clear Case IH codes. You can turn the switch on and off 3-5 times. Remove the ignition key and let the switch settle for about 10 minutes.
Turn the ignition switch on and check if this method clears the fault codes.
This method resets any computer-generated fault messages and allows the memory to start afresh with no fault codes. If the codes reappear, use the technique below.
Run the Machine for a Few Days
If you’ve fixed the underlying problem, Case IH’s memory might take time to detect the change. In this case, you can run the machine for 3-4 days. Go for long rides each day to allow this method to work effectively. If this method fails to clear the codes, check the next method.
How to Clear Case IH Fault Codes With a Diagnostic Tool
Clearing fault codes with a diagnostic tool depends on the type of machine and its model. Usually, a diagnostic scanner or laptop will get the job done.
If you have any of these tools, use this step-by-step guide to clear Case fault codes:
- Locate the machine’s diagnostic port: The diagnostic port in Case IH equipment can be on the dashboard – around the steering – or in the engine compartment. This port might be oval or rectangular with a cover.
- Connect your diagnostic tool: Remove the cover on the diagnostic port and connect your diagnostic tool. Use the correct cable or universal connector and plug it into the diagnostic port.
- Turn on the ignition key: When turning the ignition key on, remember not to start your engine. This step powers the diagnostic system, allowing your diagnostic tool to communicate with the Case IH’s computer.
- Access the fault codes: With the help of your diagnostic tool, you can find the fault code list. To do this, navigate through menus or follow instructions from the manual. Note the fault codes displayed on the machine’s dashboard.
- Clear the fault codes: Your diagnostic tool has an option for clearing the fault codes. It might require entering a command such as “Clear” or “Erase” or pressing a button. This step resets your Case IH’s computer and removes any stored codes. Check if you’ve successfully cleared the fault codes.
- Disconnect the diagnostic tool: After clearing the codes, turn off the ignition key and disconnect your diagnostic device.
- Test drive the machine: Operate your Case IH equipment to check whether this method clears the fault codes. If a Case fault code returns on display, consider further diagnosis to determine the underlying problem. After determining the root cause of the fault code, repair or replace the faulty component.
How to Clear Case Fault Codes During the Rainy Season
Fault codes can be stubborn to clear during the rainy seasons. It’s, therefore, essential to follow the correct steps to erase them. Below are the steps to follow:
- Park your Case IH on a flat surface and under a shade. You’ll want to ensure rainwater doesn’t reach your Case IH equipment.
- Turn off the engine, let it cool, and disconnect the spark plug.
- Turn the ignition key on and allow the engine to warm up for 10-15 seconds.
- Press the reset button – you’ll find it on the dashboard. Wait for the three LEDs to turn on and release the button. When all the LEDs turn on, you’ve cleared the fault codes.
How to Clear Case IH Fault Codes in Cold Weather
Cold temperatures can freeze your Case IH machine’s components, making it difficult to erase the codes. However, you can clear them using these steps:
- Turn off the engine and disengage the battery terminals.
- Remove the hood and dry clean parts like the sensor cable, filters, fuel lines, and spark plugs. You can use a dry towel or cloth to remove any ice obstructing these parts.
- Turn the ignition on and wait 15-20 minutes for the engine to warm up. Once the engine is warm, it’ll reset the memory and clear all the fault codes.
If your Case IH fault codes return after all these attempts, you’ll need to read the codes and fix the root problem. So, let’s see how you can read these codes.
How to Read Case IH Fault Codes
If the Case IH fault codes keep reappearing despite using the above methods to clear them, it’s time to resolve the root problem. To do this, you must read the fault codes to determine the causative factor. So, let’s look into two ways you can read Case IH fault codes.
Read From the Manual
The operator’s manual has a section for fault codes and what they indicate. Look for the section with the fault code list and check the codes on your machine’s dashboard. Each fault code has a meaning and effective fixes.
Read From the Diagnostic Tool
Connect the diagnostic tool to the machine’s diagnostic port and turn the ignition key on. Navigate through the menus to access the fault code list. Next, look for the section that allows you to read the codes.
Note the fault codes on your machine’s display and check what they indicate. You’ll also find info showing how to fix the root problem for each code.
You now know how to clear Case IH fault codes. If you can’t clear the fault codes with the above methods, diagnose your Case IH to determine the underlying issue. You can also contact a professional technician to help you diagnose and fix the problem.
Once your Case IH equipment is up and running, maintain it regularly to prevent these fault codes from returning.
