Does your New Holland machinery often display different fault codes on the dashboard? These error codes and their rapid flashes can be distracting and annoying. However, they’re important because they warn you of defects in your machinery.
When you see a fault code on the display, you should clear it and fix the underlying problem. And before fixing the problem, it’s necessary to read the error code to understand what it’s suggesting. This guide discusses how to clear New Holland fault codes. You’ll also learn how to read the codes and more.
Clearing Error Codes on New Holland Equipment
There are two ways to clear New Holland fault codes. You can read the code and fix the underlying problem. However, if you’re not yet ready to fix the issues in your machinery, there’s a general procedure to follow.
Below are the steps to follow when clearing New Holland fault codes:
- Turn off the engine to power down your machine. You can also remove the ignition key.
- Find the diagnostic port and remove its cover. The port is usually under the dashboard, but you can locate it in the engine compartment.
- Connect your diagnostic tool. The tool might be a scanner or diagnostic laptop. Use the appropriate cable to connect your tool to the diagnostic port.
- Turn the ignition key on without starting the engine. Doing this gives the diagnostic system power, allowing the machine’s computer to communicate with the diagnostic tool.
- Access the New Holland fault code list. You can check the list on your diagnostic tool or the manual.
- Head over to the section that allows you to clear the fault codes.
- Select the option to clear the fault codes on your diagnostic tool. In most tools, you should enter commands like “Clear” or “Erase” on the diagnostic tool. The tool might take a few seconds to clear the codes or longer.
- Once cleared, turn off the ignition key and disconnect your diagnostic tool.
- Lastly, start the engine to test drive the machine. Starting and test-driving the equipment should help know if this process resolves the issue. If the fault codes reappear, your machine requires further diagnosis and repair.
Understanding how to clear New Holland fault codes doesn’t solve the root cause of these issues. If your machine has problems, the fault codes might come back. The best way to clear these codes is to read and repair your New Holland equipment.
How To Read New Holland Fault Codes
The first step to resolving the underlying problems is reading the error codes. If you’re not tech-savvy, reading fault codes from your device might sound like an uphill task. Luckily, you can read the codes in three simple methods. They include:
Use the Manual
Your New Holland machinery comes with an operator’s manual from the manufacturer. You can use the manual as a guide to read the fault codes showing on the dashboard display.
Head to the section with the New Holland fault codes list to get started. Since these codes appear numerically, you’ll quickly see the fault code in the manual. Each fault code in the manual indicates a specific problem and how to resolve it.
Read From a Diagnostic Tool
Whether you have a scanner or diagnostic laptop, you can read the fault code on the dashboard display. Connect your diagnostic tool to the diagnostic port. Then, navigate to your diagnostic tool’s New Holland fault codes list.
Next, head over to the section that enables you to read the fault codes. You’ll see all the fault codes, their meaning, and remedies.
Use the Reset Method
You can use the reset method if you don’t have the manual or a diagnostic tool. Start by putting the brake and control lever in the neutral position. Then, turn on the ignition key and ensure your machine is functional.
To reset the equipment, locate the reset button and press it. Hold it for a few seconds and wait for the code to appear. After about five seconds, you’ll see the code with its definition.
Another option is contacting the New Holland customer care center or a qualified dealer to help you read the fault codes.
After learning the fault codes, fix the underlying problem to prevent the codes from reappearing. If you can’t resolve the issue, seek professional advice or help from a mechanic.
Most Common New Holland Fault Codes
We’ve discussed how to clear New Holland fault codes using the general procedure. What if you want to fix specific error codes? Below we’ll look into common New Holland fault codes and how to resolve the problems that trigger them.
This New Holland fault code indicates clutch solenoid failure due to low battery voltage. To clear this code, check your battery voltage to ascertain its cause. Then, recharge the battery to full capacity. If the battery doesn’t hold a charge, replace it.
This fault code stands for the engine controller failure. It might also appear due to any other hardware failure. Hire a professional to reset the engine control module or replace the engine controller.
This NH fault code results from an engine speed sensor or camshaft sensor failure. When these sensors fail, they affect the engine’s performance. To reset the code, check the sensors for signs of damage. Replace the malfunctioned sensors.
ENG 122 and 123
The ENG 122 fault code means there’s high voltage in the boost pressure sensor. On the other hand, ENG 123 occurs when there’s low voltage in the sensor. These issues negatively impact the engine’s power and acceleration.
If the problem results from high or low voltage in the sensor, use alcohol or petrol to clean it. If the code reappears, replace the sensor.
ENG 131 and 132
The fault code ENG 131 stands for excessively high voltage on the potentiometer. Conversely, ENG 132 indicates low voltage on the potentiometer. A professional can help you check the transmission system and wiring to fix the problem.
This fault code appears when the oil pressure level is too low. Low oil pressure level in New Holland machinery usually results from low-viscosity oil. To clear the code, add high-viscosity oil.
The ENG 146 fault code occurs when the coolant temperature exceeds the standard limit. The primary culprits are leaks in the machine’s cooling system, a broken pump, and hose corrosion.
To clear the code, fix any leaks, and clear the corrosion. If the issue results from a broken pump, hire a professional to replace it.
ENG 153 and 154
The ENG 153 fault code indicates a higher voltage in the intake manifold temperature sensor (IAT sensor). If you see the error code ENG 154 on the screen, it means the IAT sensor has a lower voltage.
A dirty air filter is the main culprit for high voltage in the sensor. You can clean or replace the filter to clear this code. If it reappears, replace the sensor.
This error code is seen in New Holland telehandlers (telescopic handlers). It indicates a slipping or an improperly adjusted PTO clutch. To clear the code, try to adjust the PTO clutch properly. If the fault code reappears, hire a mechanic to replace the clutch.
This fault code stands for communication issues in the armrest or transmission controller. The problem results from an error in the machinery’s transmission line. Hire a professional to diagnose and fix your machine.
ENG 319 and 329
This New Holland fault code indicates the clock in the controller system has lost power. You can clear the code by replacing the battery clock or clock.
ENG 329 fault code means the fuel pump is overpumping. You can clear the code by having the pump replaced.
Using a diagnostic tool, you now know how to clear New Holland fault codes. If this method doesn’t clear the code, you must read the fault code and fix the underlying problem. Use the operator’s manual or the diagnostic tool to read the machine’s fault codes.
If you can’t address the root cause of NH fault codes, seek advice or help from a reputable dealer or mechanic. In most cases, regular maintenance can help prevent New Holland fault codes from appearing on the screen.
