1938 code
I keep getting this code. It seems like it throws it when cold. I’m thinking it’s the actuator. I checked wiring seems ok. One thing I noticed is the def system is initializing when the code is thrown. Why would I have a def system initializing when it’s Demandated. The truck is a 2250 with 100k on the actuator. Anyone see this code when a actuator started acting up.
