    Hello. The rear view camera has not been working for some time. Just after dropping it on R (automaton), the camera turns on but there is black image. Then the problems with opening and closing the car with the button on the door handle started (now it does not work completely), the car has to be opened with the key. Now the car has a problem with starting. The board sometimes shows "Key is not detected" "Check steering wheel lock".

    A familiar mechanic, who is not an electrician, connected the car to a computer, where the U1112 error appeared.
    I googled a bit - 1 link from google with the password "hyundai ix35 2010 u1112 fault code", but since I do not know cars, I could ask for clarification what exactly is it?
    Can the battery be disconnected without any problems? Is there an option that the battery is too inefficient already and should be replaced?

    Hyundai ix35, 2010, automatic transmission, 2.0 CRDI, 183hp

    U1112 in the ECM system is an error of data transmission via the LIN data lines. In your car it applies to the AMS system, i.e. the battery sensor and the oil level sensor, if the car is equipped with this sensor. The error is not critical, but the start-stop may not work and charging the battery may not be effective. The sensor itself, the fuse and the installation to be checked, if it is an active error, if it is historical, it can be reset.
