B737 MAX pilot reported the ILS test on the First Officer side fails repeatedly. Reporter stated the problem exists and no one has been able to answer him as to why it fails.

Narrative

I'm writing to address a concern that there is an issue with the B737 MAX. Since it has returned to service; after the global grounding; I have flown it at least 13 times. I previously addressed this concern with an aviation group; but my dialogue with them came to no resolution; and it appeared there wasn't much concern.The matter I want to clarify is performing the ILS test on the First Officer side. Outside of one time on Date 1; it has never functioned correctly (12 failures). It fails each time you perform the test. It functions properly on the Captain side; but not on the First Officer side. I inform the Captain of the failure and explain the Guidance Maintenance Control will probably take; which is to pull X circuit breaker; then run the test again. Many Captains are reluctant to make an entry into the Maintenance logbook. I attempt to explain that unless we write up the discrepancy; it will continue to be ignored. After nearly a year and no guidance from Flight Operations; I'm guessing it will continue to be ignored. I am not sure how to escalate the issue rather than filing a report and hoping the aviation group will explore the matter in greater detail. Please reach out to me if you have addition questions.
