[Quick Solutions] How to Fix eBike Error Codes – Electric Bicycle – Error Code

Electric bikes (or ebikes) will display error codes to warn bikers that something about the system has gone wrong. An Electric Bike error code for Bosch, Giant, Yamaha, MAHLE ebikemotion, Panasonic or Shimano Steps motors can occur when least expected. For instance, when the sensor fails to calibrate appropriately, when the software encounters a glitch, or when the connection is interrupted.

REMEMBER: If there is any error, the e-bike will be flashing. Please connect your smartphone and open your eBike APP to get a detailed description about the error. The following are general tips and tricks on how to troubleshoot common error codes on your electric bike for your Bosch, Giant, Yamaha, MAHLE ebikemotion, Panasonic or Shimano Steps motor.

 

 

Various error codes may affect your bike’s electrical system. These may be expressed differently depending on the brand of bike you’re riding. However, the errors will have more or less the same solutions. Let us consider them below:

Why my electric bike battery is not working?

Your battery for your electric bike could be providing insufficient or incorrect voltage for your bike because the battery hasn’t been charged or there has been a blown fuse as electronic bike battery could be too high causing it to cut-off. If you have a voltmeter, you can check the voltage of an electric bike and ensuring you are using 48 or 52 volt kit. Please make sure you should also check the battery charger in case there are any faults.

Low-voltage Cut-off Protection

In this case, your bike’s battery pack is providing insufficient voltage. To correct it, recharge the battery pack. Remember to confirm that you’re using a 52V or 48V battery with your kit.

High-voltage Cut-off Protection

This will happen when your battery pack is producing too much of a voltage. In this case, you can only use a 52V or 48V battery. Remove the battery and reinsert it before starting the system again. This should remove your electric bike error code.

Electric Bike Error Codes and Solutions

Throttle Error

If the throttle on your electric fat tire electric bike is not working, try unplugging and replugging it, making sure that the arrows and pins are in line for a proper connection. Check the throttle pins to ensure they are not bent. If this does not work, unplug and replug all connections on the kit Main Wiring Harness (throttle, display, brake levers), including the connection leading to the motor lead.

Ensure that no pins are damaged and line up the pins and arrows when reconnecting for a proper connection. The last option if this does not work is to unplug the throttle from your kit. If you’re still encountering the error, you probably need a new throttle.

EBIKE-BRAND	Electric Bike Error Code	Solution
MAHLE ebikemotion	THROTTLE FAULT	Throttle damaged or out of operation. Contact your eBike dealer
MAHLE ebikemotion	TORQUE FAULT	Torque damaged or out of operation. Contact your eBike dealer.
MAHLE ebikemotion	THROTTLE NO GO BACK	Switch off the eBike System. Ensure that the throttle is released and try again.
Other	Error 04 Throttle no homing	Unplug and plug the throttle.
Other	Error 05	Throttle Abnormality. Check the throttle case for damage and check wiring for loose, pinched wire or bad connection.

Speed or Torque Sensor Error

Occasionally, the speed or torque sensors get errors as they have been overused. These are one of the most common electric bike error codes.

If it’s the speed sensor, check to see whether the Speed Sensor and magnet have been installed correctly. Ensure that the magnet is installed within 1 or 2mm of the speed sensor and the magnet’s smooth side should be facing the speed sensor. Also, be sure to fully screw the speed sensor into the motor lead plug. If this doesn’t work, it’s possible your speed sensor is broke and you need another one.

Check your brand of bike below and the solution to fix your ebike error code.

Other	Error 21 or 15H	Red light comes on when the magnet is closest and passing the sensor only. Your speed sensor may be broke, most likely need replacement.

Electric Bike Hall Sensor Error

Start by unplugging and replugging all the connections on your kit, which should include all Main Wiring Harness connections like the throttle, display, and brake levers, as well as the Motor lead connections with the Speed Sensor and Battery. Check the pins to confirm they are not bent on any connection plug and that they are in line with the arrows.

If you don’t succeed in rectifying the issue, the Hall Sensor connection from the controller to the motor core may be loose or is experiencing silicone interference blocking the connection. To fix this, try to loosen the controller to unplug and replug the Hall Sensor plug.

You’ll need to assess all the pins on the plug to ensure they are straight and get rid of any silicone interference on the connection area. From here, proceed to properly replug your white hall plug back into your bike’s motor core.

Error 08 Hall sensor; Sometimes error 8 shows if if the motor has been unplugged or if the pins are bent. Look over the motor plug to make see it is connected properly, unplug and replug and check that the plug pins are straight.

 

Temperature Error (Max Temp Protection Cut-off)

This error occurs when the electric bike is outside the agreeable temperature range (usually higher than 80 degrees Celsius or lower than -10 degrees Celsius). Turn off the e-bike system and let the drive unit heat up or cool down to the permissible temperature. Try restarting the system!

If you have a MAHLE, Panasonic or Shimano E7000, E6100 or E5000 STEPS motor, you can follow as below.

Panasonic	6A-38	The motor temperature is higher than normal, take a break and let the motor cool down.
Other	Error 10 and Error 11	The motor temperature is higher than normal, take a break and let the motor cool down.

Controller Error

If you get a controller error, you are likely in need of a new controller. However, you can try to unplug and replug all the connections and checking that there are no bent pins. Ensure everything is properly connected. There is a remote likelihood the issue could be that one of the plugs from the controller isn’t appropriately connected to the motor. Try opening the controller to see if this is the case. 

 

EBIKE-BRAND	Electric Bike Error Code	Solution
MAHLE ebikemotion	32 – COMM FATAL ERROR	Fatal Error. Restart the eBike System. If the problem persists, contact your eBike dealer.
MAHLE ebikemotion	11 – COMMUNICATION FAULT LOST FRAME JOB	Error in the communication with the Remote control. Please check the remote connector. If the problem persists, contact your eBike dealer.

Yamaha/Giant	A3	Bluetooth error – Switch the system off, wait 20 seconds to see if it works. If not, replace the RideControl Control Unit or switch off the Bluetooth device

Occasionally, the controller can also overheat. When you get this error, the implication might be that the temperature of the sensor inside the controller has likely been triggered. Allow it to cool a bit and see what happens. 

Configuration Error

This happens when there is a wrong software installation for the Line series (Performance Line) or the type of bike (Speed/Cruise, Gearbox in the hub, Derailleur). Try upgrading and updating the software to rectify the product line. From here, restart the system.

Communication Error

This may be the result of a simple connection issue. Unplug and replug every connection on the kit and this should include all the Main Wiring Harness connections, as well as all the motor lead connections with speed sensor and battery. Ensure that the pins are not bent and that they are in line with the arrows for a proper connection.

If this does not solve the situation, confirm that the wiring on your setup is not being pinched, more so the cables from the controller. Also, ensure that the wires are not too taught. Open the controller and unplug all the plugs; replug them and ensure you have no silicone interference.

 

Intermittent Power Cut-off

This will typically occur when there’s a connection issue in the battery and mount. It can lead to intermittent as opposed to constant power between the motor and battery. For the battery to power the motor adequately, it needs a solid connection with the mount connecting the battery leads to the motor. Such an issue may result from wear and tear. To fix this, follow the above guide: 

Turn the system off and remove the battery. From here, turn on the motor with the power button. Use a pair of pliers to squeeze the two outer prong connectors on the battery mount inwards while making sure that your battery has a solid connection with the battery mount.
