What You'll Learn
Check for motor obstructions
If your electric scooter is displaying an E4 error code, it typically indicates a speed or motor controller issue. Motor obstructions, such as debris, rocks, or other foreign objects, could be the culprit.
To check for motor obstructions, start by inspecting the scooter's motor for any foreign objects. Carefully remove any debris, rocks, or other items that could be obstructing the motor's movement. Ensure that you do this carefully, as you do not want to cause any further issues. Once you are happy that there are no obstructions, test the motor by spinning it to check that it moves freely and smoothly, without any unusual noises. If the motor is making unusual sounds, this could indicate an issue with the motor itself, or it could be a sign of overheating, which can be caused by obstructions.
If you cannot identify any obstructions, the next step is to check for other issues that may be causing the E4 error. This could include damaged or loose wiring, or a faulty ignition fuse. If your scooter is overheating, for example, you should let it cool down completely before attempting any further diagnostics or repairs. Check the scooter's wiring, connectors, and cables for any signs of heat damage, and repair or replace any affected components. It is also important to ensure that your scooter is regularly maintained and cleaned, as built-up dirt and dust can cause issues.
If you are still unsure about the cause of the E4 error, or if you are uncomfortable performing any of these checks, it is recommended that you consult a professional technician or the scooter manufacturer for assistance. They will be able to help you identify and resolve the issue.

Reset the scooter
Resetting your electric scooter can be a straightforward fix for many technical problems. Before beginning the reset, ensure your scooter is completely powered off and disconnected from its power source. This will prevent damage during the reset.
Next, check your scooter manual to see if it has a dedicated reset button. If it does, simply press this button to reset your scooter. If your scooter does not have a dedicated reset button, you will need to use a specific button combination. For example, the Xiaomi M365 model requires you to hold the power button for 5-10 seconds until the screen flashes. For the Ninebot Max model, turn on the scooter, then press the brake button and power button simultaneously for 3 seconds.
If you are unable to find the correct button combination for your scooter model in the manual, you can try using the mobile app if a reset option is available in the settings.
After initiating the reset, your scooter may restart or emit a sound signal. Wait a few seconds before proceeding further. After the reset, test the basic functions of your scooter, including acceleration, braking, and display. If the issue persists, repeat the procedure or contact a service center.

Inspect the wiring
Inspecting the wiring of your electric scooter is an important step in troubleshooting and resolving the E4 error code. This error can be caused by damaged or loose wiring, so it's crucial to carefully examine the scooter's wiring system. Here's a detailed guide to help you through the process:
Study the Wiring Diagram: Before inspecting the wiring, it's essential to understand how the scooter's electrical system operates. Take time to study the wiring diagram provided with your scooter. This diagram will illustrate how the components, such as the throttle, controller, motor, and battery, are interconnected. Familiarize yourself with the color-coding of the wires and the specific functions of each wire. This knowledge will be instrumental in identifying any discrepancies or issues.
Disconnect the Battery: Safety should always be a top priority when working on electrical systems. Before inspecting the wiring, be sure to disconnect the scooter's battery to avoid any accidental injuries or damage to the scooter's components. It is also advisable to wear protective gear, such as gloves and safety glasses, for added safety.
Check for Damage or Loose Connections: With the battery disconnected, carefully examine the wiring, connectors, and cables for any signs of damage or loose connections. Look for exposed wires, frayed insulation, or broken strands. Pay attention to any obvious damage and make sure that all connections are secure and properly seated.
Verify Connections with a Multimeter: To ensure that the electrical connections are functioning correctly, use a multimeter to test the wiring. This tool will help you verify that electricity is flowing consistently and accurately through the circuits. By doing so, you can pinpoint any faulty or disconnected wires that may be contributing to the E4 error.
Reconnect and Test: Once you have thoroughly inspected the wiring and addressed any issues, it's time to reconnect the battery and test the scooter. Reconnect the battery and ensure that all connections are secure. Then, perform a thorough check of the scooter's functions to ensure that the E4 error code has been resolved and that the scooter is operating optimally.

Check for loose connections
Before attempting to fix an E4 error on an electric scooter, it is important to conduct preliminary checks and ensure personal safety. Disconnect the scooter's power supply and put on protective gloves and eyewear. Keep the working area well-ventilated, well-lit, and free from clutter.
Now, you can begin to inspect for loose connections. Firstly, check if the battery terminals are securely connected. Loose connections can cause power interruptions, which may trigger the E4 error. Next, assess the overall condition of the battery. Look for any signs of wear, corrosion, or damage. A battery that has exceeded its lifespan may struggle to hold a charge, leading to errors.
Then, ensure that all connections between the motor and the controller are secure and undamaged. Controllers regulate power flow in the scooter, and issues with power regulation can trigger error codes. If your scooter has a diagnostic mode, use it to check the controller's status.
Finally, check the wiring, connectors, and cables for any damage and ensure that everything is properly connected. Loose or damaged wiring could be the cause of the E4 error.

Replace the motor controller
If you're experiencing an E4 error code on your electric scooter, it typically indicates a speed or motor controller problem. Before attempting to replace the motor controller, there are a few troubleshooting steps you can try. First, check the scooter's motor for any debris, rocks, or other objects that could be obstructing its movement and remove them. Then, reset the scooter by unplugging the battery for a few minutes and reconnecting it. Finally, inspect the wiring, connectors, and cables for any damage or loose connections, and ensure everything is properly connected.
If the issue persists and you suspect the motor controller needs to be replaced, here's a step-by-step guide:
- Purchase a replacement motor controller: It is recommended to buy a replacement from the same manufacturer or retailer to avoid fake or faulty controllers. Ensure that the new controller has the same voltage, power output, and size as the original. If your scooter has lighting or turn signals, you may need to choose a controller with those features or consider disabling them for a simpler installation.
- Prepare your workspace: Place your scooter on a table or flat elevated space for easier access to the underside. Turn off the power switch before beginning any work.
- Access the motor controller: Electric scooter controllers are typically located underneath the deck, beyond the batteries. Remove the battery cover and set it aside, taking care not to lose any screws. Then, disconnect the battery.
- Install the new motor controller: Compare the new controller with the old one to ensure they are similar. If they are not, you may need to consult a professional or refer to a wiring diagram to ensure a correct installation. Start by connecting the motor wire to the new controller, followed by the rest of the wires. Be careful not to short-circuit any connector pins or battery terminals. Ensure all wires are in good condition and securely connected.
- Reassemble the scooter: Place the battery, controller, and wires back into the deck, ensuring they are in the correct order and fit snugly. Screw on the battery cover tightly.
- Test the scooter: Turn on your scooter and test it to ensure all components are functioning properly. If you encounter any issues, consult a professional for assistance.
Note: It is important to prioritize your safety when performing any maintenance or repairs on your electric scooter. If you are unsure about any steps or encounter complications, seek assistance from a professional technician or the scooter manufacturer.
