Please kindly check whether all power already turned on.
Please kindly check whether throttle connection is correct (Throttle is Red/Back/Blue wires).
Please kindly check PAS speed level on LCD, whether it is not 0 (0 will turn off PAS and throttle).

4) Why my speed display is not correct?
Please kindly check whether you have correct setting.
Correct wheel size setting: according to your wheel size.
Correct max speed setting: set it at max value 99.
Correct P1-P5 setting: P1=46,P2=0,P3=0,P4=0,P5=12 .

5) Why always cut off during riding?
Please kindly check whether your battery support enough discharge current (Battery has enough capacity and battery BMS board support max continuous discharge current at 40A).

If your controller connect LCD display, please don't plug the jumper on cruise connector:
SM-2Y Female Black Connector with Black/Blue wires.
Please set C7=1 from LCD, save and restart LCD.
With hold throttle and keep definite speed not change, press "Down" key of LCD display Button 3 seconds at same time, cruise function is activated.  
Any other operation will cancel cruise function.
How to disable cruise function?

7) Why after turn on, LCD show "03_Info"
This is because of hall sensor abnormal, and most time is because hall sensor wires connection doesn't contact well, please kindly check the 5-wire hall sensor connector and also inside whether any pin bent doesn't contact well.If use quick release wire, please kindly check whether connector plugged very tight. If every connection is ok, then the most possible reason is hall sensor burned.
(Very important: during installation, if need to remove the white hall sensor plug, please don't let hall sensor connector terminal touch phase connector terminal, otherwise hall sensor is very easy to be burned)
