Error 310 + Corrupt or missing file: Config.json

Disclaimer: This update only works with Brose's Just Comfort display with the red color keys!

At the white key colors it doesn't work!

If you have a Marquardt just comfort display that only has 3 support steps and you want 4.

You have a Just comfort display and it gives the error Corrupt or missing file: Config.Json   

Then you can solve this by installing software version 1.8.1 on the display.

What is needed for this?
- a USB A to USB mini cable
- the bicycle on which the Just Comfort display is mounted
- The bicycle battery is preferably 100%, but in any case >80% charged - Updater Tool

 --> Step-by-step guide you can download it here.

 --> The Update Tool you can download it here.

 NB: Flashing the display is entirely at your own risk

QWIC error messages

QWIC's error messages are identical to those from Brose, except that a 2 is prefixed. Error 220 = Brose error 20. Therefore, for the non-matching errors listed below, please return to the Brose error messages. You can do this by pressing the "Back to Select Display" button.

ERROR 81 - Display/Battery - Communication failure

Check the wiring of the display and battery.

Also, check the battery connectors. There might be a short circuit somewhere.

If this problem is not resolved after swapping the components, please contact us.

ERROR 119 - Collection code

Connect the bike to the Brose Service Tool and run a full diagnostic. The corresponding error message should then be displayed. This can also be resolved with the QWIC Service Tool.

ERROR 234 - Battery - Drive Unit Connection Error - Torque Sensor Error

This error message may be caused by a short circuit or a Torquesensor error.

We kindly request that you carefully check the connection between the battery and the motor, especially the connectors in the battery compartment and the charging port. Corrosion can sometimes occur, especially around the charging port, which can then cause a short circuit. This can be easily cleaned with contact cleaner and/or a cloth or toothbrush.

If the problem persists, please contact us and we will remotely examine the engine using the Brose service tool.
