This summary uses the existing diagnostic information shown in full below.
The car's steering wheel has buttons that help control different functions. This code means there's a problem with those buttons, like pressing two buttons at once by mistake.
This code indicates an issue with the multifunction steering wheel interface, specifically a bit error or simultaneous pressing of the '+' and another button. It can also relate to a camshaft position actuator control circuit issue in certain models.
The P1565 code is triggered when the Engine Control Module (ECM) detects a bit error in the Multifunction Steering Wheel interface, or when the '+' button and another button are pressed at the same time. In some older models, it refers to an open circuit in the 'B' camshaft position actuator control circuit for Bank 1.
