4.1.2.1 Auto Scan
Auto Scan performs an automatic system test to determine which control modules are installed on
the vehicle and obtain diagnostic trouble codes (DTCs) overview. Depending on the number of
control modules, it may take 10 minutes or longer to complete the test. However, if you have used
the Models (Guide Function) to identify the vehicle, it takes much shorter time to determine the
installed controllers.
To perform an automatic system scan:
1. Scroll with the arrow keys to highlight Auto Scan from the menu and press ENTER to start.
