After the current software update, I checked for OBD Codes
2022 Bolt EUV Premier Launch Edition.
Note: Charging Port door was open, could this cause P0148?

I had 10 listed

P0148 Fuel Delivery Fault
C1043 Left Rear ABS (ICE)
P312D
C0879
C2272
C2964
C1074
C0374
C326C
P3100

I cannot find the meanings for these codes. Any help would be appreciated.

All of the C codes are communications errors.
Are any warning lights on, or are these just history codes that may have been set during programming, and not cleared by the technician?

I drove the car and tested again; all codes were gone. I can recreate the P0148 by having the charge port door open. I then connected my bi-directional scanner and looked at each module. The software sets 'C' codes when a specific test is not performed during a 'drive cycle'.

Thanks for the help
