1. A method to protect a vehicle, the method comprising:
- intercepting messages sent by a telematic dongle by a gateway that physically separates the telematic dongle from a vehicle data bus;
when the gateway is in a field state, blocking the messages sent by the telematic dongle to the vehicle data bus that include a first type of request; and
in response to the gateway transitioning to the field state, blocking the messages sent by the telematic dongle to the vehicle data bus that include the first type of request and a second type of request for a period of time.

10. A system to protect a vehicle, the system comprising:
-
a gateway in the vehicle electrically connected to a diagnostic port, the gateway physically separating the diagnostic port and a telematic dongle plugged into the diagnostic port from a vehicle data bus, the gateway including non-volatile protected memory and a processor; the non-volatile protected memory storing a value indicative of a feature status; and the processor to; when the gateway is in a field state, block messages that include a first type of diagnostic requests sent by the telematic dongle to electronic control units; and in response to the gateway transitioning to the field state, block, for a period of time, messages that include the first type of diagnostic requests and a second type of diagnostic requests sent by the telematic dongle to the electronic control units. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
