ReadDataByIdentifier simulation results (CAN line)
And the CAN line log.
There’s a long message in there, so I’ve omitted that part.

End TriggerBlockSome thoughts on the results of the ReadDataByIdentifier simulation.
The multi-DID specification is still troublesome.
For the user side, it is good because it improves data collection efficiency, but for the design side, it is troublesome for both the off-board tester and the ECU side.
A request for a DID that does not exist is an error, but if there is a DID that exists as a multi-DID, it is not an error, or all DIDs exist as DIDs, but it is an error due to the response message length.
Well, on the other hand, it is not so scary because we already know the trouble.
It is just a matter of incorporating it into the test items from the beginning.
Conclusion.
- Check the results of the ReadDataByIdentifier simulation.
- Confirmation of the message.
- Check CAN line logs.
- Multi-DID specification is tricky.
- A request for a non-existent DID is an error.
- However, if the DID exists in the multi-DID, it is not an error.
- If the DID exists, it is not an error.
- However, an error may occur due to the response message length.
- A request for a non-existent DID is an error.
