The TCU is capable of showing 7 error messages and notifications.

We support both Riders and Retailers with further advice how to resolve issues:

For Riders, error messages, their meaning and potential solutions are covered in:

1. Mission Control App – here, messages are translated into User Actions in case of live bike issues.
2. Turbo bike manuals – here, we give general advice what to do in case of error messages

As a Retailer, you have deeper diagnostic insights by using Turbo Studio:

1. Always run digital diagnostics through the Event Log after having connected the bike to Turbo Studio or after the Rider has uploaded the „Advanced Diagnostic“ via Mission Control.
2. Service Actions are aimed at helping you to resolve issues at workshop level

Although the Service Actions are the most important reference within digital troubleshooting, it is worth knowing the fundamental difference between component „errors“ and „not found“ or „no xy“ messages:

• Component errors can be caused by a defect component, but there are exceptions – for instance, a missing speed sensor magnet would trigger a motor error. Errors always require further investigation and, potentially,  the replacement of parts.
• “Not found” or “no xy” messages are mostly caused by communication issues between components and often relate to a lost connection. The root cause could be a loose/damaged connector or a defect cable.
