Last night, as a celebration for my Forester turning 1 month old, I had the Check Engine light come on with a whole bunch of other warnings for nearly every function. I noticed my fog lights, which were on, not illuminated. The fuse had blown, so I replaced it and removed the aftermarket LED light bulbs, with the OEM bulbs installed as replacements. The fog lights worked again but my dash was still lit up like a Vegas casino. A trip to AutoZone revealed code U0284. They couldn’t tell me what it meant. Dr. Google suggested in other years/models that the code is related to the active grill shutter. I couldn’t identify specifically the fuse and/or relay for this so I just removed and inspected about 80% of them. Finally, I decided I’d rather dig further into the situation in my driveway instead of the AZ parking lot near closing time (10PM). I started up my vehicle and no CEL. It must be that time or my fuse R&R cleared it. Lucky me?
