Flashing CDL, no codes, help? (1 Viewer)

[acruisinf]

On cold start, I’ve got a flashing CDL, a few times per week. Every time it happens, I fire up OBD Fusion to check codes. Diagnostics show everything normal, no codes.
Vehicle performs normal, no noticeable odd behavior.
2015 with ~116k.

Any ideas? Thanks!

I took mine out in the pasture and did slow figure 8s. No issues since.

It will do that if you haven't used it in a while. If you use it every couple weeks, even for just 3 minutes, it tends to not happen.
