If you bought it new, you now have to register the device before it allows you to access to diagnostics. A year or two ago you were limited to about 10 cars before forced to register units , and several years or more ago, if the software it had on it was good enough to get by on with older cars, you could postpone registration for quite awhile without need to update getting newer car coverage that potentially disable some older car software functionality. Autel put an end to this practice since the warranty and 1 year update period started the day you registered the unit and they were likely to incur more warranty expense and not sell as many Total Care Updates .
WARNING , IF OUT OF UPDATE PERIOD WITHOUT DESIRE TO BUY AN UPDATE, DO NOT DO A FACTORY RESET AND THINK A COPY AND PASTE OF SCAN FOLDER BACKUP, WILL FIX IT. YOU WILL NEED TO CONNECT IT TO INTERNET AFTERWARDS AND GET AN ERROR CODE IF EXPIRED AND NOT BE ABLE TO ACCESS DIAGNOSTICS. ONLY DELETE THE PROBLEM APP AND CHERRY PICK WHAT YOU NEED FROM YOUR BACKUP SOFTWARE TO ATTEMPT REPAIR!
