Q: Check engine light is on with codes U110C and U0140
Having problems with the warning lights on my car. The car was turned off, but all of the lights on the dash were on. I pressed the door lock and all the lights turned off. I let the car sit for a bit, and turned it back on. It runs normally, but now the check engine light is on. I got these two codes: U110C Manufacturer Control and U0140 Lost Communication With Body Control Module. What do these mean and how do I fix it?
