Scanner Operations
5.3 Operations
The Scanner allows you to establish a data link to the electronic control systems of the vehicle
being serviced in order to view live data parameters and perform tests. Data may be available from
multiple systems, such as engine, transmission, antilock brake system (ABS), and others.
Functional tests, troubleshooting tips, and trouble code information are typically available.
The Scanner has two main functions:
1. Scanner—provides access to vehicle systems to perform functions such as reading codes,
viewing data, and conducting functional tests.
2. Troubleshooter—provides the diagnostic power of Troubleshooter, a database of experience
based information developed by master technicians.
After a system is selected and the Scanner establishes communication with the vehicle, a
Scanner Main menu, which lists available tests, displays.
