When the U0422 fault code appears on the Ford F-150, it means there's a problem with the Body Control Module (BCM), which acts as the car's main computer. The BCM oversees and manages the various electronic components in the vehicle. If there's an issue with the BCM, it can impact the operation of other parts that rely on it for proper functioning. Signs of a faulty BCM can include unusual occurrences like hazard lights flickering or unexpected warning lights on the dashboard. It's crucial not to delay addressing a faulty BCM since it plays a vital role in the car's operation, so it's best to have it inspected promptly.
