Oil Status Indicator

The oil status indicator will light when the engine starts, but then that part of the VMM goes blank. Any ideas why?

This is what the manual says: The module lights all segments of the display for 1 second, blanks them for 1 second, and then goes to normal operation whenever the ignition key switches to the RUN position. The oil change display turns off after 15 minutes if the VMM module is not getting a tachometer signal. This is a diagnostic precaution that could be caused by the engine not running or an intermittent connection.
Is this what you're experiencing or does it go blank after less than 15 minutes?

It goes out immediately.
