# UpdateDecoderManifest
<a name="API_UpdateDecoderManifest"></a>

**Important**  
 AWS IoT FleetWise is no longer open to new customers. Existing customers can continue to use the service as normal. For more information, see [AWS IoT FleetWise availability change](https://docs.aws.amazon.com/iot-fleetwise/latest/developerguide/iotfleetwise-availability-change.html).

 Updates a decoder manifest.

A decoder manifest can only be updated when the status is `DRAFT`. Only `ACTIVE` decoder manifests can be associated with vehicles.
