All MiX 4000 devices running firmware version 4.10 will unlock the auto-commissioning feature when connected to CAN.
If an asset has been created in MiX Fleet Manager with the same VIN number that was read from the CAN bus, the device IMEI will be assigned to the asset automatically, hence linking the asset and MiX mobile device automatically.
In these cases, the VIN source is set to CAN bus (after the CAN scan is completed) and the CAN protocol, fuel type and VIN fields on the asset details page will be locked for editing.
When an asset is decommissioned/mobile device is removed, the VIN source will no longer be set to CAN and the locked fields will be unlocked again.
