1 Charge the Battery
Charge the e-bike until the battery reaches over 10%, making sure the charger indicator turns red and the battery level increases. Then, reboot the e-bike to check if the error code still exists. If charging fails or the charger indicator displays an abnormal status, proceed to the next step.
2 Replace the charger if it doesn't work properly
Replace the charger with a new spare and charge the e-bike until the battery reaches over 10%. Then, reboot the e-bike to check if the error code still exists. If charging fails or the error persists, proceed to the next step.
3 Check the Charging Port
If the e-bike's battery is charged through a charging port on the frame rather than directly plugging the charger into the battery, replace the charging socket 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.
(The reason for needing to reboot the e-bike is that the system will detect whether the error code still exists during the reboot.
This allows us to determine whether the troubleshooting mentioned above has successfully resolved the issue.)
4 Connect the bike to DST and update Battery Firmware
Connect the e-bike to the Trek Dealer Service Tool and update the [Battery] firmware to the latest version. Then, reboot the e-bike to check if the error code still exists. If charging fails or the error persists, proceed to the next step.
5 Replace the Battery
Replace the [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.
