display status report even though the module is disabled
That's not possible.

For hooks to be executed, your module must be enabled. From the docs:


  To extend Drupal, a module need simply implement a hook. When Drupal wishes to allow intervention from modules, it determines which modules implement a hook and calls that hook in all enabled modules that implement it.


Emphasis mine.

Allowing modules to run code even when they're not enabled would be a massive security risk, and could cause all sorts of other unforeseen problems.
