Hard alarm every 60 sec. safe mode

[Bigmike58]

I have a weird one. Hooked up the rinds to a 2016 5.7. Alarms exactly every 60 secs. Nothing pops up on the dash display.

Boat does go into “guardian” mode

I will attemp to attach pics of the diagnostic screens.

The SPN = 110 will put it in guardian mode.
