Use the Vehicle Diagnosis Tester to get the anti-theft code. The radio card and the label on the radio that were used in the past are no longer used.
• The Vehicle Diagnostic Tester must be "online" (network connection) to access the anti-theft code. The user must have proper authorization to access the anti-theft code.
