Tailgate pushbutton remote control
WARNING: This page is about a different car, the 2013 BMW X5, 2012 BMW X5, and 2011 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
The radio signal of the remote control is received via the rear window aerial. The remote control receiver forwards the signal via the K-CAN to the Car Access System. The Car Access System has the central responsibility for the function of the central-locking system. The ID transmitter used in vehicles with Comfort Access has the same functionality as the remote control.
