What's the u0422 code Ford f150?

When the U0422 fault code displays on the Ford F-150, it is an indication there is a fault in the Body Control Module (BCM). This is the component of the car that functions as the car's computer. It monitors and regulates the numerous electronic components of the car. If there is a problem in this unit, it will affect the functioning and performance of other parts, as they depend on it to work accurately. You might notice abnormal things like Your hazard lights flashing, or random lights on the instrument cluster signaling warnings. A faulty BCM isn't something to suspend repair on, as it is a central part of the car, so get it checked out immediately.
