Toyota forklifts are known for their quality and reliability in material handling environments. However, like any other machinery, they can experience problems or malfunctions from time to time. When this happens, the forklift’s system will generate specific diagnostic codes that indicate the nature and location of the issue. These codes are also known as fault codes or error codes.
Fault codes are useful tools for troubleshooting and resolving the identified problems. They can help you determine whether you need to perform some simple maintenance tasks or call a professional service technician.
Here we will explain how to reset Toyota forklift codes in a simple and easy way. We will also provide some information about the most common fault codes and how to examine them on your forklift’s display panel. By following these steps, you can ensure that your Toyota forklift is running smoothly and efficiently.
Overview of the Fault Codes for Toyota Forklifts
Fault codes are alphanumeric codes that appear on your forklift’s instrument panel when a problem or malfunction occurs in the system. They usually consist of a letter followed by one or two digits, such as A5, F1-1, or H1-2. The letter indicates the general category of the fault, such as E for electrical, F for CPU, or H for hydraulic. The digits indicate the specific component or function that is affected by the fault, such as 1 for OPS/SAS system, 2 for potentiometer, or 3 for sensor.
Different models and series of Toyota forklifts may have different sets of fault codes, so it is important to consult your owner’s manual or service manual for the exact meaning and description of each code. However, here are some of the most common fault codes that you may encounter on your Toyota forklift:
| Fault Code | Meaning | Possible Effect |
| A5 | OPS/SAS system failure | The OPS/SAS system is designed to prevent accidents by detecting the presence of the operator and controlling the stability of the load. If this system fails, it may cause unsafe operation or damage to the forklift or its surroundings. |
| F1-1 | OPS/SAS data reception fault | This code indicates that there is a communication problem between the OPS/SAS system and the CPU. This may affect the accuracy and reliability of the OPS/SAS system. |
| F4-1 | CPU error | This code indicates that there is a problem with the central processing unit (CPU) of the forklift. The CPU is responsible for controlling and monitoring various functions and components of the forklift. If this code appears, it may cause erratic or abnormal behavior of the forklift. |
| H1-2 | Lift potentiometer failure | This code indicates that there is a problem with the potentiometer that measures the position of the lift cylinder. The potentiometer is a device that converts mechanical motion into electrical signals. If this code appears, it may cause inaccurate or incorrect lifting operations. |
| H1-3 | Tilt potentiometer failure | This code indicates that there is a problem with the potentiometer that measures the position of the tilt cylinder. The tilt cylinder is responsible for tilting the mast forward or backward to adjust the angle of the load. If this code appears, it may cause inaccurate or incorrect tilting operations. |
These are just some examples of fault codes that you may encounter on your Toyota forklift. There are many more codes that cover different aspects and functions of your machine. To learn more about them, you can refer to your owner’s manual or service manual.
How to Examine the Error Codes on a Toyota Forklift
To examine the error codes on your Toyota forklift, you need to access the diagnostic mode of the system. The diagnostic mode is a special mode that allows you to view and clear the fault codes, as well as perform some tests and adjustments. To access the diagnostic mode, you need to follow these steps:
- Turn the key switch to the ON position, but do not start the engine.
- Wait for about three seconds until the instrument panel displays the hour meter reading.
- Press the accelerator pedal five times within five seconds.
- The instrument panel will display “DIAG” and enter the diagnostic mode.
Once you are in the diagnostic mode, you can use the display panel buttons to navigate through the different menus and options. The display panel buttons are usually located below or beside the instrument panel, and they may have different labels depending on your forklift model. However, they usually have the following functions:
- UP or +: This button allows you to scroll up or increase the value of a parameter.
- DOWN or -: This button allows you to scroll down or decrease the value of a parameter.
- ENTER or OK: This button allows you to select or confirm a menu or option.
- ESC or CANCEL: This button allows you to exit or return to a previous menu or option.
To view the fault codes, you need to select the “FAULT CODE” menu from the main menu of the diagnostic mode. You can use the UP or DOWN button to scroll through the different menus, and press the ENTER button to select one. The “FAULT CODE” menu will display the current and history fault codes that are stored in the system.

The current fault codes are the ones that are active at the moment, while the history fault codes are the ones that have occurred in the past but have been cleared or resolved.
The fault codes are displayed in a numerical order, starting from 01. Each code is followed by a letter that indicates its status: C for current, H for history, or E for erased. For example, if you see “01 F1-1 C”, it means that fault code F1-1 is currently active. If you see “02 H1-2 H”, it means that fault code H1-2 has occurred in the past but has been cleared or resolved.

You can use the UP or DOWN button to scroll through the different fault codes, and press the ENTER button to view more details about each code. The details may include the description, location, cause, and solution of the fault. You can also press the ESC button to return to the previous screen.
How to Clear Fault Toyota Forklift Codes
After examining and fixing the problem that caused the fault code, you may want to clear it from the system. Clearing a fault code means erasing it from the memory of the system and resetting its status.
There are two methods to clear fault codes on a Toyota forklift: one by disconnecting the battery and another by using the display panel buttons.
Method 1: Disconnecting the battery
One of the simplest methods to clear fault codes on a Toyota forklift is by disconnecting the battery. This method works by resetting the electronic control unit (ECU) of the system, which is responsible for storing and processing the fault codes. To disconnect the battery, you need to follow these steps:
- Turn off the engine and remove the key from the key switch.
- Locate the battery compartment of your forklift, which is usually under the seat or behind the counterweight.
- Open the battery compartment and disconnect the battery terminals by loosening the clamps with a wrench.
- Wait for about 30 seconds to allow the ECU to reset.
- Reconnect the battery terminals by tightening the clamps with a wrench.
- Close the battery compartment and start the engine.
After disconnecting and reconnecting the battery, you should check the instrument panel to see if the fault code has disappeared. If it has, it means that the problem has been resolved and the system has been reset. If it has not, it means that the problem still exists or there is another issue that needs attention.
Method 2: Using the Display Panel Buttons
Another method to clear fault codes on a Toyota forklift is by using the display panel buttons in the diagnostic mode. This method works by selecting and erasing each fault code individually from the system’s memory. To use this method, you need to follow these steps:
- Access the diagnostic mode by following the steps described in the previous section.
- Select the “FAULT CODE” menu from the main menu of the diagnostic mode.
- Scroll through the different fault codes until you find the one that you want to clear.
- Press the ENTER button to view more details about the fault code that you want to clear.
- Press the ESC button to return to the previous screen.
- Press and hold the ENTER button for about three seconds until you see “ERASE” on the display panel.
- Press the ENTER button again to confirm the erasure of the fault code.
- The display panel will show “ERASE OK” and return to the previous screen.
- Repeat steps 3 to 8 for each fault code that you want to clear.
- Press the ESC button until you exit the diagnostic mode.
After using the display panel buttons, you should check the instrument panel to see if the fault code has disappeared. If it has, it means that the problem has been resolved and the system has been reset. If it has not, it means that the problem still exists or there is another issue that needs attention.
