CAN conformance testing

Minor improvement of ISO 16845-1

The internationally standardized CAN conformance test plan was published in 2016. Experts have detected some minor issues, which have been improved unofficially.

The automotive industry is committed to specify not just in-vehicle network protocols, but to standardize also related conformance test plans. The test plan for the CAN protocol is standardized in ISO 16845-1.

The last edition has been released in 2016. In the meantime, experts have found some issues regarding testing the REC (receive error counter) increment on CRC (cyclic redundancy check) errors.

Due to the fact that the ISO 16845-1 document cannot be updated frequently, CiA has published an improved specification for this test case on its website. Of course, this update will be submitted, when the test plan is going to be systematic reviewed.

The conformance test plan for high-speed transceivers compliant with ISO 11898-2:2016 is still under development. When the submitted comments are implemented, the document will be finally balloted. Publication is expected by end of this year.
