Action: Check the cable connection. Many times error code 10 occurs due to a loosely connected communication cable between the motherboard and the display.
Error code 11: Wrong phase current A
Description: Error code 11 is most often linked to problems with phase current A (blue) and is caused by moisture and corrosion.
Action: Inspect phase A on the motherboard. If moisture intrusion or corrosion is detected, correct these problems to restore normal operation.
Error code 12: Wrong phase current B
Description: Error code 12 is most often linked to problems with phase current B (brown/black) and is caused by moisture and corrosion.
Action: Inspect phase B on the motherboard. If moisture intrusion or corrosion is detected, correct these problems to restore normal operation.
Error code 13: Wrong phase current C
Description: Error code 13 is most often linked to problems with phase current C (yellow) and is caused by moisture and corrosion.
Action: Inspect phase C on the motherboard. If moisture intrusion or corrosion is detected, correct these problems to restore normal operation.
Error code 14: Faulty throttle control
Description: Error code 14 is usually linked to problems with the throttle and its cable.
Action: Check throttle, display unit and cable connection. The throttle body contains two magnetic poles that may need to be adjusted if they have separated due to shock or vibration.
Error code 15: Incorrect brake handling
Description: Error code 15 can occur due to problems with the brake control and its cable.
Action: Inspect the brake control, display unit and cable connection. The brake control also contains two magnetic poles that can be damaged by impacts or corroded by contact with water.

Action: Try reinstalling the firmware or consider replacing the motherboard if the problem persists.
Error code 28: Short circuit of motor control MOS upper bridge
Description: Error code 28 relates to a short circuit in the motor control MOS upper bridge.
Action: Replace the motherboard to fix this problem.
Error code 29: Short circuit of motor control MOS lower bridge
Description: Error code 29 indicates a short circuit in the motor control MOS lower bridge.
Action: Replace the motherboard to resolve this issue.
Error Code 35: Invalid device serial number
Description: Error code 35 is associated with an incorrect device serial number.
Solution: Identify the motherboard with the scooter's serial number (for example, Essential/1S/Pro2 can use the Xiaoflasher app to pair the serial number).
Error code 39: Incorrect temperature from the battery sensor
Description: Error code 39 indicates incorrect temperature from the battery sensor.
Action: Replace the battery or repair the Battery Management System (BMS).
Error code 40: Incorrect temperature from the motherboard
Description: Error code 40 is linked to incorrect temperature from the motherboard.
Action: Check the motherboard. It may be necessary to replace the motherboard if the problem cannot be resolved.
