pin diagnostic connector into the OBD-II interface module. Also make
sure you have the vehicle’s ignition turned to the ON position, or go
ahead and start the engine.

Manager?
Yes:
Continue to the next step.
No:
Right-click on your desktop and click the “Properties” menu item. This
will open the Display Properties dialog. Click the “Settings” tab and
check your screen resolution setting. For best results, we recommend
running a screen resolution of at least 800x600. Now click the
“Advanced” button in the lower right corner of the same dialog. This will
open another dialog. Make sure your DPI setting is set to “Normal size
(96 DPI)”. If it was set to something else, you will need to restart your
computer for the display changes to take effect.
7. Can you establish a connection with the vehicle by clicking the “Connect”
button on ProScan’s Vehicle Connection Manager?

Congratulations, you can begin using ProScan on your vehicle!
No:
Continue to the next step.
8. Are you receiving an error stating that the serial port could not be opened?
Yes:
Make sure that no other application is currently using the serial port. If
you have previously used any other serial device, there may be another
application using the serial port. Exit any such applications or command
them to quit using the serial port.
If you are using a USB-to-Serial adapter, make sure that you have
installed the drivers according to the manufacturer’s instructions. Also
make sure that the serial port being emulated by the adapter is the one
selected under ProScan’s Communication Settings.
No:
Continue to the next step.
