16. Issue: 

My printouts contain the wrong Shop name and phone number. 

Reason:  The contact information page was incorrectly filled out 
Fix:  Access the contact information page by touching the on-screen start menu in the 
lower left hand corner of the screen. Select information and then select user and the 
contact information page should appear. Edit the information using the keyboard icon 
located in the lower right of the screen.  

You will need to reboot your Launch tool for the 

change to take effect. 

 

17. Issue:

  The connector called for by the tool does not work, what should I do? 

Reason:

  

The screen displays all connectors used on the particular vehicle make. 

Fix:   Use the connector guide supplied by your authorized distributor. It is updated 
monthly and   should be very accurate. If you find inaccurate information in the 
connector guide, please contact your Authorized Distributor so it can be corrected.
