4.3.1 Connecting the Scan Module
The Scan Module is a wireless device that is connected (using the vehicle data cable) to the
vehicle and transmits vehicle data to the Diagnostic Tool. To use the Scanner function the Scan
Module must be paired with the Diagnostic Tool. If the Scanner tries to communicate with the
vehicle and the Scan Module is not connected to the vehicle, a Connect Data Cable confirmation
screen will display. For Scan Module connection and operation information, see
4.3.2 Vehicle Identification
Connection of the data cable and Scan Module to the diagnostic tool and vehicle DLC is required
for Scanner testing.
Vehicle identification is the initial step in using the Scanner function. Once vehicle identification
information is entered it is saved in Vehicle History and can be selected again for later use to save
time when testing the same vehicle.
