Radio antennas

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.

To check function of the radio antennas, the following tests are run.

The diagnostic fault memory entry "DAD2 diversity not connected" indicates an interruption in the connection from the CCC to the antenna diversity.
The antenna self-test is started and queried. If a fault is displayed, there is a problem with the antenna structure or the connection from the CCC to the antenna structure. The fault "DAD2 diversity not connected" must not be entered in the fault memory.
