6. The FixAdvisor will automatically start a
check of the vehicle’s computer to determine
which type of communication protocol it is
using. When the FixAdvisor identifies the

communication link is established, and the

lists the three most recently selected vehicles.
A PROTOCOL is a set of rules and
procedures for regulating data
transmission between computers,

and computers. As of this writing,
five different types of protocols
(ISO 9141, Keyword 2000, J1850

manufacturers. The FixAdvisor automatically identifies the
protocol type and establishes a communication link with the
vehicle’s computer.
