Radio antennas

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.
