The Bosch system is continuously monitored. If an error is detected, the corresponding error code is displayed on the on-board computer. The drive may be automatically shut down, depending on the type of error. However, if you wish to continue cycling, you will always be able to do so without assistance from the drive. Before undertaking any other journeys, the Carqon should be checked. Have all repairs performed only by your own Carqon dealer or at an authorised Carqon dealer.
