3.2 Step-by-Step Instructions

Identify the Fault Code: Use the dashboard display or a diagnostic tool to identify the fault code.
Address the Underlying Issue: Before clearing the fault code, it’s crucial to address the underlying issue that caused it. For example, if the fault code indicates a low oil level, top up the oil before proceeding.
Turn Off the Forklift: Turn off the forklift and remove the key from the ignition.
Disconnect the Battery (Optional): For some models, disconnecting the battery for a few minutes can clear the fault code. Locate the battery and disconnect the negative terminal.
Use the Diagnostic Tool to Clear the Code: If you have a diagnostic tool, connect it to the forklift and use the tool’s interface to clear the fault code.
Reconnect the Battery (If Disconnected): If you disconnected the battery, reconnect the negative terminal.
Turn On the Forklift: Turn on the forklift and check if the fault code has been cleared. If the code persists, repeat the steps or seek professional assistance.
Test the Forklift: After clearing the fault code, test the forklift to ensure it’s functioning properly.

3.3 Alternative Methods for Clearing Fault Codes

In some cases, you may be able to clear fault codes without a diagnostic tool or disconnecting the battery. Here are a couple of alternative methods:

Driving Cycle: Some fault codes will clear automatically after the forklift completes a specific driving cycle. Refer to the forklift’s manual for the exact driving cycle required.
Key Cycling: Turn the ignition key to the “on” position for a few seconds, then turn it off. Repeat this process several times, and the fault code may clear.

3.4 Troubleshooting Common Issues

If you encounter issues while trying to clear fault codes, here are some troubleshooting tips:

Fault Code Persists: If the fault code persists after clearing it, the underlying issue may not have been fully resolved. Revisit the troubleshooting steps and address any remaining problems.
Diagnostic Tool Not Connecting: Ensure the diagnostic tool is properly connected to the forklift’s diagnostic port and that the tool is compatible with the forklift model.
Battery Disconnection Issues: If you disconnected the battery, make sure the terminals are clean and properly reconnected.
