I had a check engine light come on referring to excessive regen while driving and not towing. Cleared alarm and truck drives fine but looking through truck info on dash it says Regen is in process but it never clears or stops. I drove some with exhaust brake on constant and it gave me a message of repetitive regens, turned off exhaust brake and cleared check engine light and has been fine until now. I can't tell if DEF usage is up, doesn't seem to be. Any ideas on action needed.
