Code
Sub Error CodeWhat Code MeansHow to Fix/Repair issue
A
FAFront motor communication issue/failureCheck front motor wire and see if any damage and check controller 3 phase wires (Yellow, Green, Blue) for heat damage.

bARear motor communication issue/failureCheck rear motor wire for damage and check controller 3 phase wires (Yellow, Green, Blue) for heat damage.
bBad throttleReplace throttle
CFCFront motor hall sensor faultCheck motor wires and 3 phase wires at controller for any damage. If no damage then motor will need to be replaced.

bCRear motor hall sensor faultCheck motor wires and 3 phase wires at controller for any damage. If no damage then motor will need to be replaced.

EUnder voltage alarmCheck battery voltage to make sure battery is not defective. If battery voltage good then replace
F
FF
Over Current alarm of front drive controller
1.The MOSFET is damaged/short circuited after shutdown. This requires replacing the controller.
2. In the process of high-speed riding, when suddenly passing through a pothole or going faster than designed down hill. The motor is subject to strong resistance and generates a large reverse current. This will disappear after turning off. If not then controller will need to be replaced.

bF
Over current alarm of rear drive controller
1.The MOSFET is damaged/short circuited after shutdown. This requires replacing the controller.
2. In the process of high-speed riding, when suddenly passing through a pothole or going faster than designed down hill. The motor is subject to strong resistance and generates a large reverse current. This will disappear after turning off. If not then controller will need to be replaced.

dF
Over current alarm of Dual drive controller
Read Above.
H
Brake handle Failure
Check brake handle wires and inspect switch for any damage. If no damage then replace brake handle.
d
Fd
Front motor stall alarm
Push motor and should self recover to fix the issue. If not, then turn unit off then back on.

bd
Rear motor stall alarm

Push motor and should self recover to fix the issue. If not, then turn unit off then back on.

dd
Dual motor stall alarm
Read Above
L
bL

Rear Starting Current is Abnormal
Unplug both controller's power supply/plug from battery. If this does not reset the error code then you need to replace REAR controller.


FL
Front Starting Current is Abnormal

Unplug both controller's power supply/plug from battery. If this does not reset the error code then you need to replace FRONT controller.
