Routing activation establishes a diagnostic path through a DoIP entity. A rejection at that stage is different from a module failing during programming.

Interpreting the evidence

Save the exact rejection and distinguish it from a later diagnostic negative response. Review tool compatibility, authorised access and the approved connection requirements. If no programming operation started, describe the incident accurately rather than reporting an interrupted flash.

Keep this evidence

Provide the vehicle identity, tool version and the last successful connection stage.

A routing rejection does not authorise bypassing access controls. The next step is the supported connection or account route for that vehicle.
