Mercruiser service soon message?

[lrdchaos]

Just pulled the new to me 2015 350 mag out of storage and installed a new Dist cap and rotor bug. I noticed when I started the boat it had a service soon message, any way to check what it was? The boat starts, idles and runs great on the muffs. Much smoother that when I ran it a couple weeks ago to dewinterize it.
There are no audible beeps or other messages.
Also, in only cycles across the screen right after the system boots up. It will say smart craft and then service soon. Nothing scrolls when it’s running.


thanks in advance.

Also, will low voltage cause this service soon code? The boat has old batteries that are going to be replaced tomorrow. They show 12.3 on the digital boat meter.
