Snap-on® reminds automotive repair technicians it’s good practice to perform a pre-scan before vehicle work is done to spot any hidden issues and make the customer aware of problems. The pre-scan code identification helps speed the diagnosis and repair, and when followed by a post-scan after work is finished, confirms all were completed properly. It gives the shop something to hand to their customer, showing them the issues found on the vehicle when it first arrived and how those have been resolved now, aiding customer satisfaction.
