## Properties
<a name="aws-properties-iotfleetwise-decodermanifest-obdsignaldecoder-properties"></a>

`FullyQualifiedName`  <a name="cfn-iotfleetwise-decodermanifest-obdsignaldecoder-fullyqualifiedname"></a>
The fully qualified name of a signal decoder as defined in a vehicle model.  
*Required*: Yes  
*Type*: String  
*Minimum*: `1`  
*Maximum*: `150`  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`InterfaceId`  <a name="cfn-iotfleetwise-decodermanifest-obdsignaldecoder-interfaceid"></a>
The ID of a network interface that specifies what network protocol a vehicle follows.  
*Required*: Yes  
*Type*: String  
*Minimum*: `1`  
*Maximum*: `50`  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`ObdSignal`  <a name="cfn-iotfleetwise-decodermanifest-obdsignaldecoder-obdsignal"></a>
Information about signal messages using the on-board diagnostics (OBD) II protocol in a vehicle.  
*Required*: Yes  
*Type*: [ObdSignal](aws-properties-iotfleetwise-decodermanifest-obdsignal.md)  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`Type`  <a name="cfn-iotfleetwise-decodermanifest-obdsignaldecoder-type"></a>
The network protocol for the vehicle. For example, `CAN_SIGNAL` specifies a protocol that defines how data is communicated between electronic control units (ECUs). `OBD_SIGNAL` specifies a protocol that defines how self-diagnostic data is communicated between ECUs.  
*Required*: Yes  
*Type*: String  
*Allowed values*: `OBD_SIGNAL`  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
