Q: What does code U0265 mean?

Lost Communication With Image Processing Sensor A. U0265 means the module that supervises the vehicle's camera-based driver-assist system has stopped receiving valid data from Image Processing Sensor A, which is typically the forward-facing camera or its processing unit. The supervising module sets this code when the expected periodic CAN (Controller Area Network) messages from that sensor time out or fail their checksum, indicating a communication breakdown rather than a confirmed sensor failure.
