U024ELost Communication With Side Obstacle Detection Control Module C

U024E is a communication fault where the vehicle's main network controller has lost contact with the side obstacle detection control module C, which is one of the modules responsible for blind spot monitoring and cross-traffic alert on one side of the car. The computer has detected that the module is not responding to periodic network messages, so it flags the module as offline and disables the related driver-assist features.
