Now the check engine light is on and the cylinder head and diagnostic head, something is wrong. They will fix the diagnostic head but not the cylinder head.

For example, it may work normally when I first start the car in the morning and back out of my parking spot, but later the same day—such as when I arrive at work—the camera stops working completely. The display stays black and does not recover even after shifting between gears or restarting the system. After parking and locking the car for a while, the ca
