ERROR CODE DEFINITION
The DP C01.UART display can show e-bike faults. When a fault is detected, the icon will be displayed. In the
speed field one of the following error codes will be displayed:
Error Explanation Troubleshooting
03 Brakes enabled Check whether a brake cable is stuck.
07 High voltage protection Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
08 Fault with motor hall sensor inside Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
10 The motor temperature reaches to
the max protection value Stop the e-bike for a rest.
12 Fault with current sensor inside
controller
Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
13 Fault with temperature sensor inside
battery
Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
21 Fault with wheel speed detecting
sensor
Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
22 BMS communication fault Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
25 Torque sensor torque signal fault Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
26 Torque sensor speed signal fault Bring your Pedelec to your dealer or to a
specialist to have the error fixed.
30 Communication fault Bring your Pedelec to your dealer or to a

Note: Error Code 10 will probably appear on the dispaly when the e-bike is climbling for a
long time. This indicates that the motor temperature has reached the protection value, in
which case the user needs to stop the e-bike for a rest. If the user continues to run the e-
bike, the motor will automatically cut off the power.
