車両診断通信 [Dcm] Vehicle Diagnostic Communication Part 64 [Simulation 3]
The interface specification of AUTOSAR-Dcm is figured out.The buffers for communication are managed by AUTOSAR-Dcm, which is a memory-saving and copy-saving design implementation.AUTOSAR-Dcm consists of three sub-modules.dsl: Diagnostic Session Layer.dsd: Diagnostic Service Dispatcher.dsp: Diagnostic Service Processing.

The following is an example of a specific transmission/reception of the WriteDataByIdentifier service.I have explained examples of transmission/reception including NRC$78.
車両診断通信 [DoCAN] Vehicle Diagnostic Communication Part 60 [UDS 21]
Explanation of the request message for the WriteDataByIdentifier service.Unlike the ReadDataByIdentifier service, one DID is fixed.Explanation of the response message of the WriteDataByIdentifier service.In practice, NRC$78 may be interleaved.

The WriteDataByIdentifier service has been explained.Usage scenarios.Communication characteristics tied to non-volatile memory.
車両診断通信 [DoCAN] Vehicle Diagnostic Communication Part 58 [UDS 19]
Confirmed single DID transmitted and received.Confirmed transmitting and receiving multi-DIDs.Confirmed some DIDs are undefined patterns.
車両診断通信 [DoCAN] Vehicle Diagnostic Communication Part 57 [UDS 18]
Explanation of the request message for the ReadDataByIdentifier service.Multiple DIDs can be set.There may be a limit on the number of DIDs that can be set, and it is an error if the number is exceeded.It is also an error if the response message exceeds 4095 bytes.Explanation of the ReadDataByIdentifier service response messageCombination of DID and dataRecord.In case of multiple DIDs, the above combination is placed in one message.
