⚠️Caution
Prior to proceeding with the troubleshooting steps below, AVOID swapping the current Extender Battery with another functioning bike or replacing it with a new Extender Battery on the problematic bike for testing purposes. Incorrect steps may result in misdiagnosing the issue and potentially triggering additional error codes.
1 Check the Connection Cable
Long press the power button to turn off the e-bike.
Ensure the connection cable between the Extender Battery and the e-bike is securely plugged in. If it's loose, plug the connector back in tight carefully.
2 Reboot the e-bike
Reboot the e-bike to check if the error code still exists. If this doesn't fix the issue, proceed to the next step.
3 Replace the Connection Cable
Replace the [Connection Cable] between the extender battery and the e-bike with a new spare, then reboot the e-bike to check if the error code still exists. If this doesn't fix the issue, proceed to the next step.
4 Replace the Charging Socket Cable
Replace the main battery's [Charging Socket Cable] with a new spare, then reboot the e-bike to check if the error code still exists. If this doesn't fix the issue, proceed to the next step.
5 Replace Both [Main Battery] and [Extender Battery]
Replace the [Main Battery] with a new spare, then reboot the e-bike to check if the error code still exists. If this doesn't fix the issue, proceed to the next step.
