As you all know, the ECO model has the grill shutters. The shutters have to be removed when installing aftermarket FMIC kits. This threw two codes: P069E, and U0284. The P069E is available, and as I understand it, it sets whenever the fuel pressure control module system has a fault (it must control the shutters because the car ran great, no fueling issues). The U0284 is not available to be disabled.
Can U0284 be added to the DTC list for the Cruze? Should I email support with any additional information? Another option (if it's available) would be a master enable/disable for the shutter system. Since it seems to be a part of the FPCM, I'm not sure if it's a possibility. Again, just let me know if you need me to email anything to support.
Thanks!
