2016 Buick Enclave P018B, P2635, U0074, U8A2 Codes Not Clearing After Fuel Pump Replacement

Hi everyone, My daughter drives a 2016 Buick Enclave that recently started making a squealing fuel pump noise, accompanied by a check engine light. She took it to a trusted repair shop where the fuel pump was replaced. However, the diagnostic codes—P018B, P2635, U0074, and U8A2—still remain and won't clear after the replacement. The mechanic suggested that the issue might be with the fuel pump control module (FPCM), which may require reprogramming. Unfortunately, he couldn’t perform this reprogramming on-site, so he recommended visiting the dealership. The dealer responded that they don’t recognize the need for FPCM reprogramming and believe the problem lies solely with the fuel pump itself. I’m confused about why these codes persist after a new fuel pump installation. Any insights or explanations regarding these specific OBD2 codes in a 2016 Buick Enclave would be greatly appreciated. Thanks in advance for your help!
