Abstract: A mobile communication system of a motor vehicle includes a primary antenna. The system further includes a telematics module having a processor and at least one memory including a computer program code. The memory and the computer program code are configured to, with the processor, cause the system to detect a predetermined vehicle event and measure a primary signal quality of the reference signal received at the primary antenna. The memory and the computer program code are configured to, with the processor, cause the system to determine a maximum primary signal quality and compare the maximum primary signal quality with a threshold. The memory and the computer program code are configured to, with the processor, cause the system to determine a defect in the primary antenna and activate a diagnostic trouble code associated with the defect, in response to determining that the primary maximum signal quality is below the threshold.

Abstract: A communication system for a vehicle includes a transceiver and a telematics control module. The transceiver receives data from a network device using first antennas disposed external to a vehicle and second antennas disposed internal to the vehicle. The transceiver receives the data using a first antenna combination including two antennas, which include one or more of the first antennas or one or more of the second antennas. The telematics control module: reads channel state information including reference signal received power (RSRP) and rank indicator (RI) values; determines if the RSRP value is greater than a threshold value and the RI value is less than a minimum number of antennas being used to transfer the data; and based on the first RSRP value being greater than the threshold value and the RI value being less than the number of antennas, switches from the first to a second antenna combination.

Abstract: A system for updating vehicle time information includes a communication device configured to wirelessly communicate with a wireless network using a network communication protocol. The system also includes a processing unit configured to assess communications between the vehicle to determine whether a condition related to a potential local time offset error exists, and based on determining that the condition exists, transmit a message supported by the communication protocol to the wireless network. The message is configured to prompt the wireless network to return a response message including a local time offset. The process is also configured to update a vehicle local time record based on the local time offset.
