It is important to note that if you are unsure of the specific problem and solution, it is recommended to consult a Calf U dealer or technical support department for help and support. Before attempting any repair, be sure to turn off the power and take the necessary safety measures to ensure your personal safety.
1, it may be caused by the power supply circuit failure. The battery car suddenly does not supply power, which can lead to failure to start, which may be caused by poor contact between the battery and the car line or the motor and controller being burned out.
Solution: It is recommended to check the power supply system in time.
2. Power lock, check whether several wires of the power lock are securely inserted and whether there is line breakage. If the power lock is opened, the vehicle has no power, it can not start.
Solution: Check whether the power lock cable and the solder joint of the lock head are disconnected. It is recommended to reconnect and weld the solder joint.
Low battery power: The battery power may be consumed during the scrubbing process, resulting in insufficient power to ignite. You can try to connect the electric car to the charger to charge, make sure that you are fully charged before trying to ignite.

Ignition system failure: The cleaning process may cause the ignition system failure, such as ignition switch damage, ignition line short circuit, etc.
There may be a number of reasons why the Calf APP cannot start the vehicle.
First of all, it may be because the network is unstable or the signal is poor, which makes it impossible to connect to the vehicle's controller for starting operation.
Second, it may be because the battery is low or the vehicle fails to start normally.
Again, it may be because there is a problem with the user's account or vehicle information that it cannot be identified or authorized to start.
Therefore, it is recommended that users check the network connection status, vehicle power and fault situation, as well as the account and vehicle information is normal, and contact the customer service of Niu in time to solve the problem.
for the following reasons
Could be a fault in the power supply circuit.
Power lock, check whether the power lock several wires are firmly connected, whether the plug is good, whether there is a broken line.
Electric car brake power off, but not in place, may still be power off.
The handle, the controller, the circuit, the motor all broke.
The connection between the power cable and the battery is loose.
Check whether the electric vehicle battery output is normal.
The steering wheel is locked.
