AWS IoT FleetWise is no longer open to new customers. Existing AWS IoT FleetWise customers can continue using the service. The [Guidance for Connected Mobility on AWS](https://aws.amazon.com/solutions/guidance/connected-mobility-on-aws/) provides guidance on how to develop and deploy modular services for connected mobility solutions that can be used to achieve equivalent capabilities as AWS IoT FleetWise.

# Manage AWS IoT FleetWise vehicle models
<a name="vehicle-models"></a>

You use signals to create vehicle models that help standardize the format of your vehicles. Vehicle models enforce consistent information across multiple vehicles of the same type, so that you can process data from fleets of vehicles. Vehicles created from the same vehicle model inherit the same group of signals. For more information, see [Manage AWS IoT FleetWise vehicles](vehicles.md).

Each vehicle model has a status field that contains the state of the vehicle model. The state can be one of the following values:
+ `ACTIVE` – The vehicle model is active.
+ `DRAFT` – The configuration of the vehicle model is saved. 

**Important**  
You must have a signal catalog before you can create a vehicle model using the `CreateModelManifest` API operation. For more information, see [Create an AWS IoT FleetWise signal catalog](create-signal-catalog.md).
If you use the AWS IoT FleetWise console to create a vehicle model, AWS IoT FleetWise automatically activates the vehicle model for you.
If you use the `CreateModelManifest` API operation to create a vehicle model, the vehicle model stays in the `DRAFT` state.
You can't create vehicles from vehicle models that are in the `DRAFT` state. Use the `UpdateModelManifest` API operation to change vehicle models to the `ACTIVE` state.
You can't edit vehicle models that are in the `ACTIVE` state.
