MUKUTA electric scooters are known to be a popular choice for commuting and off-road riding. However, encountering error codes can sometimes disrupt the smooth operation of your scooter. This article is designed to help you understand these codes and learn how to troubleshoot them, which can help you get back on track quickly.
COMMON ERROR CODES
# ERROR CODE 00: NORMAL STATUS
This error is the exception to all of the others, it could mean one of two things.
1. Your system had a fault detected somewhere that has since resolved itself or it was detected in error.
2. You have a system error that will arise via another error code in the future.
Troubleshooting Step: Turn the scooter off and on again to reset your system
Resolution: Normally, after reset, the error code will not pop up again.
# ERROR CODE 02: BRAKES
This error is the result of a malfunctioning brake. Whether it's a brake lever that's not functioning properly or brake calipers not going back to their original position, something in your braking system is not working properly. (Take disc brake as an example)
Troubleshooting Step 1: Work your way from the top down. Start at your brake lever and ensure that after being pressed, it springs back to its original position.
Resolution: After giving a few hard presses if it doesn't spring back to the original position, work to find the source of the blockage.
Troubleshooting Step 2: If the lever is functioning properly, move on the calipers. Here we'll need to check that the brake lines spring back to their original position.
Resolution: If they aren't use a little WD40 to make sure it springs back to its original position. If both the lever and the calipers are in proper working order, do a reset of the scooter and the error code should go away.
(But for oil brakes, check whether the brake power-off switch sensing module is displaced.)
# ERROR CODE 06: BATTERY UNDER VOLTAGE
When most riders see this and look it up somewhere, their first thought is "Oh no, my battery must be failing!" Considering it's an electric scooter, that concern is fully warranted, but some simple setting adjustments may be causing this malfunction and the problem isn't as dire as it seems.
Troubleshooting Steps: Check your LCD and access the P03 and P15 settings. Give the battery a full charge and see if the issue persists.
Resolution: Some factory settings are set lower than what's optimum for function and performance. For example, in some cases, the MUKUTA 10PLUS 60V 20.8ah will have its P03 setting set at 52V, this should be set to 60V. It is worth mentioning that the voltage value of P15 will be automatically adjusted according to P03 without manual setting.
# ERROR CODE 07: MOTOR FAULT
This error can be an especially alarming one, much like the battery because the cost of replacement (outside of the warranty) can range from $150-$500 depending on the model you have. Generally speaking, the MUKUTA motors have been proven to be of good build quality, so let's check some other things that could've triggered the E07.
Troubleshooting Steps: Check your LCD and access the P03 and P15 settings. Give the battery a full charge and see if the issue persists.
1. Unplug the motor wire (phase wires) and plug them back in until you hear a secure click sound to see if the code persists. Also, repeat this process with the Hall Sensor to ensure it's securely connected.
Resolution: If #1 worked for you, fantastic, you're ready to go. If not, and the connections in step #2 all look solid and have no signs of wear, you may need to replace the motor entirely.

# ERROR CODE 07 ADDITIONAL STEP FOR DUAL MOTORS
Additional troubleshooting Steps:Unplug the Phase Wire and Hall Sensor wire and plug them into the opposite motor connections. In doing so, this will help you easily determine which motor is causing the fault.
# ERROR CODE 08 THROTTLE
This error code comes up when the throttle isn't reacting as it should to the rider. For this troubleshooting, you'll need an Allen wrench.
Troubleshooting Steps:
1. Disconnect the connector between the LCD and the main control cable and re-plug it.
2. Disconnect the connector between the throttle and the LCD and plug it in again.
3. Check the throttle magnet (make sure it hasn't moved out of position) and hall sensor for damage or disconnection. The hall sensor will have 3 links on it, all 3 must be intact.
4. Check the throttle spring to ensure it's seated correctly and functioning as it should. The trigger should immediately spring back to its original position if functioning properly.
Resolution: After steps 1-4, you should be ready to ride, but if an error code persists, you will need to replace the LCD/Throttle assembly entirely.
# ERROR CODE 09: CONTROLLER
When thinking of the controller, think of it as the nerve center of your scooter. For most situations, this means something has burned out as a result of harsh riding, water damage, or your MOSFET burning out.
Troubleshooting Steps:
From a troubleshooting standpoint, there is not a list of steps to try and fix the problem, but rather steps that need to be taken to ensure that the E09 code is truly a controller. Each retailer of MUKUTA products is different, but this is a warrantied part so they'll ask for a video confirming this issue. Here's what will need to be included in the video:
Place your scooter above ground level (on a crate, chair, jack stand, etc.), take the deck cover off, take a continuous video with the VIN number and the controller serial number in the shot, and then film the issue at hand. This should give the engineer looking at the video a good idea of what the issue is.
Resolution: Change out the controller entirely. One note, the white wire going to the controller is the speed limiter, if that is not something you need to remain lawful while driving the scooter, leave it disconnected. Otherwise, it is a wire-for-wire hookup and will be fairly straightforward.
# ERROR CODE 10/11: COMMUNICATION/ RECEIVING FAULT
These error codes most often present themselves when a quick twitch turning of the handlebars happens and a loose connection is a result. There are 2 steps we can go through to check to make sure the wiring harness didn't produce a code in error.
Troubleshooting Steps:
1. Gain access to under your deck and search in front of the controller for the round black waterproof connection to the wiring harness. In some cases, it may be easier to remove the controller to gain easier access. Once you've found the connection, unplug and plug it back in to ensure a proper connection.
2. Check the round black waterproof connection going into the LCD to ensure it is properly connected and sealed.
Resolution: After going through Steps 1 and 2 you should be in good shape. If the problem persists, you will have to replace the wiring harness entirely.
General Troubleshooting Tips:
# Restart the Scooter
Often, a simple restart can resolve minor glitches. Turn off the scooter, wait for a minute, and then turn it back on.
# Check Connections
Ensure all cables, connectors, and components are securely connected and free from damage or corrosion.
# Update Firmware (if applicable)
Some error codes might be resolved by updating the scooter's firmware. Check the manufacturer's website for any available updates.
# Inspect for Physical Damage
Examine the scooter for any visible damage, loose parts, or wear and tear that might be causing the error.
# Consult the User Manual
The scooter's user manual often contains specific error code explanations and troubleshooting steps provided by the manufacturer.
# Contact Customer Support
If none of the above steps resolve the issue, reaching out to MUKUTA's customer support or a certified technician is recommended for further assistance.
