For certain vehicles (e.g., select Dodge, Chrysler, Jeep, RAM, Alfa Romeo, Fiat, Maserati, and Nissan models), unlocking security gateway modules may require an AutoAuth account.

7. Maintenance

Proper maintenance ensures the longevity and reliability of your Autel ML619 scanner.

• Cleaning: Use a soft, damp cloth to clean the exterior of the unit. Do not use abrasive cleaners or solvents.
