Abstract
In an example of a method for performing vehicle antenna diagnostics, a transmitting and receiving (TX/RX) antenna of a multiple input multiple output (MIMO) antenna assembly of a vehicle is electronically caused to emit a check signal. A response of a receiving only (RX) antenna of the MIMO antenna assembly is electronically detected in response to the check signal. A received signal strength indictor output is generated in response to the response of the RX antenna. The received signal strength indictor output is converted to a digital signal. The integrity of the MIMO antenna is determined after comparing the digital signal with an expected power level of the RX antenna.
