Troubleshooting
When controller detects failure, the truck stops working. LCD gives fault identification codes.
The LCD uses two-digit code. Two short flashing and one long interval means 11,two short flashing,
one short flashing and one long interval means 21, etc.
Note: Error code might change due to updated controller versions. Please refer to the actual
instructions on the controller or contact the technician.
No Error Code Error Possible Cause
1 11 Parameter error Wrong parameter setting
2 12 Overcurrent Motor short circuit or controller failure
3 14 M+ current 0 bit detection error Controller failure
4 15 M- current 0 bit detection error Controller failure
5 18 Motor hall sensor error
Motor hall sensor failure, controller failure, or
bad connection
6 19 Temperature sensor failure
Temperature sensor failure or circuit
disconnection
7 21 Potentiometer error Acceleration potentiometer failure or circuit fault
8 22 Overheating current limit Controller is overheated, causing current limit
9 23 Overheating protection
Controller is overheated, and automatically
stops working
10 25 Over temperature, current output limit Motor over temperature, current output limit
11 26 Motor stall Motor stall protection
12 27 Electromagnetic brake error
Electromagnetic brake is broken, causing open
circuit
13 29 Motor open circuit Motor open circuit or Motor failure
14 31 Low battery voltage, current limit Low battery voltage causing current limit
15 32 Low battery voltage protection Low battery voltage, truck is shut down
16 33 High battery voltage Lithium battery with high temperature
17 35 Contactor error Controller failure
18 38 Communication error LCD display fault or harness fault
19 39 Controller version error Controller version is not updated
