Rapid blinking CEL, only @ idle?

[SquareOne]

Question on a 13 Cascadia w/ISX... My truck has an auto-shutdown when idling too long (not sure of the interval, but it seems to be 5min or less). Very rarely do I ever let it idle. Most of the time I bump the idle from 650 to 8-900 if for some reason I have to get out with the truck running. The oil press will come up 10+ lbs easily (typically 23-24 @ hot idle, 35+ when rpm bumped up). Here's my question...

- Have any of you with the auto-shutdown feature, in a Cascadia, noticed a rapid blinking CEL (picture of the eng with the word "check", at the upper left corner of the cluster) just before shutdown?


This may not be what it is, but as soon as a touch the throttle, the light will go out. Insite has no recorded event and it only seemed to occur the 2 times I jumped out and didn't bump the idle (again after a few minutes, not right away). At first I thought it was a low oil pressure warning, but then I got to thinking maybe this is the warning just before the auto-shutdown...a countdown just before the engine actually cuts off?

I skimmed through the owner's manual but did not see any info regarding this.

Thanks everyone.
