[CAN-FD] Vehicle Diagnostic Communication Part 87 [python-can 1]

BusMaster does not support CAN-FD.The asc format of CAN-FD is different from CAN.FDF bit and BSR bit parameters are added.

[CAN-FD] Vehicle Diagnostic Communication Part 85 [Overview 1]

Switch from CAN to CAN-FD for the physical and data link layers.CAN-FD is described in Vector's "CAN/CAN-FD for Beginners".

[Dcm] Vehicle Diagnostic Communication Part 84 [Simulation 23]

We saw a pattern of returning NRC$10 (generalReject) when NRC$78 (ResponsePending) exceeds a certain number of times.This specification is not specified in ISO 14229-1.However, it is likely to be a de facto standard.Therefore, it is assumed that it is incorporated as an AUTOSAR specification.

[Dcm] Vehicle Diagnostic Communication Part 83 [Simulation 22]

Check the results of the WriteDataByIdentifier simulation.Confirmation of the message.Confirmation of CAN line.Often used in conjunction with ReadDataByIdentifier to check operation for reading after writing.NRC$78 returned atmosphere.In fact, NRC$78 is rarely followed three times.

[Dcm] Vehicle Diagnostic Communication Part 82 [Simulation 21]

I wrote Python code to simulate WriteDataByIdentifier.WriteDataByIdentifier is often protected by session and security, so the main test is to test it.

[Dcm] Vehicle Diagnostic Communication Part 81 [Simulation 20]

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.

[Dcm] Vehicle Diagnostic Communication Part 80 [Simulation 19]

I wrote Python code for simulation of ReadDataByIdentifier.Test pattern main related to ReadDataByIdentifier multi-DID.Multi-DID.Mix unsupported DIDs.Specify DIDs such that the response message length exceeds the maximum value.

[Dcm] Vehicle Diagnostic Communication Part 79 [Simulation 18]

Check the results of the TesterPresents simulation.Verification of messages.Checking the CAN line log.TesterPresents with suppressPosRspMsgIndicationBit is a special AUTOSAR-Dcm specification.After S3 time extension in Dsl, the message is discarded and not passed to Dsd and Dsp.The result is different from ISO14229-1, but the practicality is more important.
