Imagine you’re about to start your shift at work, ready to tackle the day’s tasks with your trusty Toyota forklift. But as soon as you turn on the ignition, you notice something’s not quite right. The dashboard display flashes a series of numbers and letters fault codes. Don’t worry just yet! Fault codes are signals from your forklift’s onboard computer system that something isn’t working correctly. Clearing them is an easy process. In this step-by-step guide, you’ll learn how to Clear Fault Codes on Toyota Forklift and get back to business as usual.

List Of Various Toyota Forklift Fault Codes

Toyota forklifts are known for their reliability and durability, but just like any other machinery, they can develop faults from time to time. When a fault occurs, the machine will display a specific code on its dashboard screen to indicate what is wrong. Understanding these fault codes can help you diagnose and fix problems quickly before they become more significant.


The EC-1 code indicates a communication error between the lift truck’s control system and electric motors. When this happens, the forklift’s computer cannot communicate with its drive motor controller. This issue can cause significant problems in your daily operations, preventing you from effectively controlling your machine. It is essential to address this issue promptly, as it can lead to decreased performance and potentially costly repairs. These problems can cause reduced engine power and increased fuel consumption if left unchecked. In some cases, they may even lead to engine failure.


While being a Toyota forklift owner, you might have encountered the dreaded F4-1-8 fault code at some point. This error code is common and can cause your forklift to stop working. But what exactly does it mean, and how can you fix it? Let’s see.

The F4-1-8 fault code indicates a problem with your Toyota forklift’s speed control system. This could be due to a faulty speed sensor or wiring issues. When this happens, your forklift will not be able to maintain a constant speed, which can be dangerous if you’re carrying heavy loads. To fix this, check the wiring harnesses and connections on the speed sensor. If everything seems fine there, you might need to replace the speed sensor.

F1-1 and F2-1

The F1-1 code typically appears when there is an issue with the accelerator pedal circuit. This can be caused by a faulty sensor or damaged wiring, leading to an inconsistent signal being sent to the engine control module. On the other hand, F2-1 refers to an error in the hydraulic system pressure sensor circuit, which could cause problems with lifting loads or steering. To resolve these issues, it is recommended that you consult with your Toyota forklift dealer, who can provide technical support and guide you through troubleshooting steps.

H1-2 and H1-3

H1-2 and H1-3 fault codes indicate issues with the forklift’s hydraulic system. The H1-2 code signifies low hydraulic oil pressure in the system due to leaks or incorrect oil levels. In contrast, an H1-3 error indicates high hydraulic pressure in the system caused by obstructions or blockages within the hydraulic lines or components.

H2-1 and H2-2

The H2-1 code indicates an issue with the fuel system, particularly the fuel pressure. A clogged fuel filter, a malfunctioning fuel pump, or a leak in the fuel line could cause this. To resolve this issue, check and replace any faulty components in the fuel system. If you’re unsure of how to do this yourself, it’s best to contact a certified technician for assistance. On the other hand, the H2-2 code signifies a problem with the throttle position sensor (TPS).

05-01, 05-02, 05-03, 05-04, 05-05:

The first code, 05-01, indicates a problem with the brake pedal switch circuit. This could be caused by a faulty switch or wiring issues in the circuit. The second code, 05-02, points towards an issue with the accelerator pedal position sensor circuit. This code usually appears when there is a problem with the sensor or its wiring connections. Code 05-03 indicates an issue with the accelerator pedal circuit. This could be due to a damaged or worn-out pedal or a faulty sensor. Sometimes, it could also indicate a problem with the wiring connecting the accelerator pedal to the truck’s computer system.

The 05-04 code has concerns with the steering system. Specifically, it means that the steering angle sensor is not functioning properly. If you see the 05-05 error code, it signals an issue with the hydraulic system.

Determining the cause

Determining the cause of a fault code on your Toyota forklift is important to avoid costly repairs, downtime, and equipment damage. The first step to clearing fault codes is understanding what they mean. When a problem arises within one of the systems, the computer generates a fault code that indicates which component has failed or malfunctioned. To determine the cause of the fault code, you must access the diagnostic menu on your forklift’s display panel. The display will provide specific codes for your forklift’s parts or functions.

Once you have identified which system has triggered the error message, it’s time to troubleshoot and diagnose what went wrong.

Taking out the battery

This can be done by disconnecting the negative terminal cable from the battery. Care should be taken when doing this, as batteries can contain potentially hazardous materials and should only be handled by properly trained individuals. Once the battery has been removed, waiting a few minutes before proceeding further is important. This will allow any residual electrical charges that may still be present in the forklift’s system to dissipate. Once enough time has passed, reattach the negative terminal cable and turn on your ignition key.

Go For a maintenance reset

After taking out the battery, it is important to carry out a maintenance reset to clear any fault codes that may have been stored. A maintenance reset will also help to ensure that all systems are functioning at their optimal level and prevent any future issues. Start by reconnecting the battery and turning on the ignition to carry out this. Now, locate the diagnostic port under the dashboard of your forklift and connect a diagnostic tool. Once connected, follow the prompts on the tool to initiate a system scan and clear any fault codes that are present.

Important Note: Clearing fault codes without addressing underlying issues can be dangerous. Always consult a trained technician or mechanic if you are unsure how to diagnose and repair any faults in your Toyota forklift properly.

How to reset the Toyota forklift cat code?

While operating a Toyota forklift, you may see the CAT code indicating an issue with the catalytic converter. To reset this code, several steps need to be followed:

  • Turn off the forklift and remove the key from the ignition.
  • Locate the diagnostic port under the dashboard on the driver’s side of the forklift.
  • Use a jumper wire to connect terminals TE1 and E1 in this port.
  • Turn on the ignition without starting the engine.
  • Wait for 30 seconds before removing the jumper wire from TE1 and E1.
  • Press down on both brake pedals and hold them in place for five seconds.
  • Release both pedals simultaneously and wait for two seconds before pressing down again for another five seconds.

How can I tell if my engine is broken?

There are a few ways to tell if your engine is broken. One way is to listen to unusual noises coming from the engine. Another way is to look for signs of leakage or oil on the ground. If you notice any of these signs, it might be time to take your car in for repair.

Why won’t my electric forklift proceed?

Make sure the power is on and that the battery is fully charged. Now, check to see if the forks are in the up position. If they are not in the up position, check to see if something is blocking the forks from moving. If nothing is blocking the forks, check if something prevents the belt from moving.
