If you operate a Hyster forklift, you know how frustrating fault codes can be. These alerts pop up when something isn’t quite right, and they can stop your work in its tracks.
But here’s the good news: you don’t always need a technician to clear these codes. You can reset Hyster fault codes yourself—quickly and effectively—so your forklift gets back to work with minimal downtime. In this guide, you’ll learn simple steps and insider tips to reset those fault codes safely and confidently.
Ready to take control and keep your Hyster forklift running smoothly? Let’s dive in.
Locate Diagnostic Port
Start by finding the diagnostic port, usually inside the driver’s cabin or near the engine. This port connects to tools needed to read and clear fault codes on Hyster forklifts. Accessing it is the first step to reset fault codes properly.
Finding the diagnostic port is the first step to reset Hyster fault codes.
This port allows access to the forklift’s error system for troubleshooting.
The diagnostic port usually sits inside the operator’s compartment or near the engine bay.
It often looks like a small, rectangular plug with multiple pins.
Look around the dashboard area or under the steering column for easy access.
Sometimes, it may be hidden behind a small cover or panel.
Check Operator’s Compartment
Most Hyster forklifts have the diagnostic port within the driver’s area.
Scan around the control panel and near the seat base.
Locate any removable panels or plastic covers that might hide the port.
The port is designed for quick connection to diagnostic tools or scanners.
Inspect Engine Bay Area
If you cannot find the port inside, check the engine compartment.
Open the engine cover and inspect around the fuse box or wiring harness.
The diagnostic port is often mounted near electrical components for easy wiring.
Take care not to disconnect any cables accidentally while searching.
Use The Forklift Manual
The user manual provides exact location details for the diagnostic port.
Refer to the troubleshooting or electrical section of the manual.
It may include pictures or diagrams to guide your search.
Using the manual saves time and avoids damage during the process.

Use Display Panel
The display panel on a Hyster forklift shows fault codes clearly. It helps operators reset these codes without extra tools. Using the display panel is often the quickest way to clear errors.
Follow simple steps on the panel to access fault information. This allows you to act fast and reduce downtime. The process involves turning the key on, navigating menus, and sometimes using key or pedal sequences.
Turn Key To On
Insert the key into the ignition and turn it to the “On” position. Do not start the engine. The display panel will light up and show the current status of the forklift. This step powers up the system for fault code access.
Navigate To Clear Faults
Use the arrow buttons on the display panel to find the “Clear Faults” menu. Scroll carefully through the options. Select this option to view active fault codes. Confirm to clear the codes if no issues remain.
Use Key/pedal Sequences
If the display panel does not clear the faults, try key or pedal sequences. These involve pressing pedals or keys in a specific order. This method can reset some fault codes without additional devices. Refer to your forklift manual for exact sequences.
Try Battery Disconnect
One simple way to try and reset Hyster fault codes is by disconnecting the battery. This method can clear temporary errors stored in the system. Disconnecting the battery cuts power to the forklift’s electronics, allowing the control module to reset. This often clears fault codes that do not indicate serious problems. Follow these steps carefully to safely disconnect and reconnect the battery.
Disconnect Main Terminal
First, turn off the forklift and remove the key. Locate the battery compartment. Use a wrench to loosen the nut on the negative terminal. Always disconnect the negative (black) terminal first to avoid sparks. Remove the cable carefully and secure it away from the battery. This prevents accidental contact and short circuits.
Wait Before Reconnecting
Leave the battery disconnected for about five to ten minutes. This pause allows the system to fully power down and reset. After waiting, reconnect the negative terminal first. Tighten the nut securely but do not overtighten. Finally, reconnect the positive (red) terminal. Turn on the forklift and check if the fault codes have cleared.

Apply Diagnostic Software
Applying diagnostic software is essential for accurately resetting Hyster fault codes. This software helps communicate with the forklift’s electronic system. It reads error codes stored in the system and allows you to clear them safely. Using software reduces guesswork and prevents improper resets that might cause more issues.
Diagnostic tools offer a clear view of the forklift’s health. They save time and improve maintenance efficiency. Follow the steps below to apply diagnostic software correctly.
Connect Jaltest Tool
First, locate the forklift’s diagnostic port. This port is often near the driver’s seat or engine compartment. Connect the Jaltest diagnostic tool to this port using the supplied cable.
Turn the forklift’s ignition key to the “On” position without starting the engine. This powers the system and allows the tool to communicate with the forklift. Wait for the Jaltest tool to establish a connection with the vehicle’s control unit.
Read And Clear Codes
After connecting, navigate the Jaltest menu to the fault code section. The tool will display all active and stored fault codes. Carefully review these codes to understand the issues.
Select the option to clear or reset the fault codes. The software will erase the stored errors from the system memory. After clearing, turn off the ignition and disconnect the Jaltest tool.
Start the forklift and check if the faults have been reset. If codes reappear, further troubleshooting or repairs may be required.
Fix Underlying Issues
Fixing the root causes of Hyster fault codes is essential to keep your forklift running smoothly. Simply clearing the codes without solving the problem can lead to repeated errors and downtime. Identifying and fixing underlying issues prevents future faults and improves safety. Focus on key areas that commonly cause faults.
Inspect Connections
Loose or damaged electrical connections often trigger fault codes. Check all wiring harnesses for wear, corrosion, or breaks. Secure any loose plugs and clean dirty terminals. Proper connections ensure signals pass correctly between components. This step often resolves communication faults quickly.
Check Fluid Levels
Low or contaminated fluids can cause system errors. Check hydraulic oil, transmission fluid, and engine oil levels. Top off any fluids below recommended amounts. Replace fluids if they look dirty or thick. Maintaining correct fluid levels helps avoid sensor errors and mechanical problems.
Test Sensors
Faulty sensors send wrong data, creating error codes. Use a multimeter or diagnostic tool to test sensor resistance and output. Focus on key sensors like temperature, pressure, and position sensors. Replace any sensors that fail tests. Accurate sensor readings are vital for proper machine operation.

Follow Model-specific Steps
Resetting Hyster fault codes is not the same for every model. Each model can have unique steps for clearing these codes. Following the exact process for your model ensures the fault codes reset properly. This prevents errors from returning quickly. It also helps avoid damage to the forklift’s system. Always focus on the model-specific instructions. This approach keeps your forklift running smoothly and safely.
Check For Password Access
Some Hyster models require a password to reset fault codes. This adds a layer of security. The password protects the system from unauthorized changes. Locate the password in your documentation or from your dealer. Entering the correct password unlocks the reset function. Without it, you may not clear the codes. Always keep your password safe and accessible.
Consult User Manual
The user manual holds the key to resetting fault codes. It contains detailed instructions tailored to your forklift model. Manuals explain the exact button sequences or display commands to use. They also warn about precautions during the reset process. If you lack a physical copy, download a digital version from the Hyster website. Following the manual reduces trial and error. It saves time and protects your equipment.
