If your vehicle is not listed in the Specific Vehicle Exceptions, but if you are observing odd behavior, it
may be that the CarChip is trying to initialize a protocol that your vehicle does not use. When the CarChip
is first connected to a vehicle it cycles through the list of protocols to find the protocol that the vehicle is
using. If a protocol is selected from the list, the next time the CarChip is placed in a vehicle the selected
protocol is used. Do not select a specific protocol if you do not know your vehicle's protocol. Contact
Technical Support for assistance regarding selecting a specific protocol if you are uncertain.
