1. A system comprising:
- a control unit included in a vehicle including a processor and a memory;
a first radio frequency transceiver included in the vehicle and communicatively coupled to a vehicle communication bus included in the vehicle,a first antenna connected to the first transceiver;
a second radio frequency transceiver included in the vehicle and communicatively coupled to the vehicle communication bus; and
a second antenna connected to the second transceiver;
wherein the control unit is programmed to;
provide a command via the vehicle communications bus to set the first transceiver in a transmit mode and set the second transceiver in a receive mode;
instruct the first transceiver to transmit a first test signal at a first predetermined strength via the first antenna; and
receive data representing at least one characteristic of a first return signal from the second transceiver based upon the first test signal received by the second antenna.

Abstract
A system includes a control unit and multiple transceivers connected by a communication bus. The transceivers are respectively connected to antennas. The control unit tests the operation of the transceivers by transmitting a test signal from a first transceiver to a second transceiver, receiving a return signal based on the test signal from the second transceiver, and determining if the strength of the return signal is within a predetermined range.

20. A method, carried out according to instructions stored in a non-transitory read memory of a control unit in a vehicle comprising:
-
setting, via a vehicle communications bus in the vehicle, a first in-vehicle radio frequency transceiver included in the vehicle and connected to a first in-vehicle antenna in a transmit mode; setting, via the vehicle communications bus in the vehicle, a second in-vehicle radio frequency transceiver included in the vehicle and connected to a second in-vehicle antenna in a receive mode; instructing the first transceiver to transmit, via the first antenna, a first test signal at a first predetermined strength; receiving data representing a strength of a first return signal from the second transceiver based on the first test signal received by the second antenna; and determining if the strength of the first return signal is within a first predetermined range.
