"This Service Information Bulletin outlines a new required procedure to follow when performing immobilizer-related repairs on the all-new 2020 Legacy and Outback. To further enhance vehicle security, this new procedure requires connection to a secure SBR server for authentication and to access immobilizer information. An 8-digit “Authentication Key†supplied by SBR will be a required input when working with SSM4. Unlike the previous system where Teaching Codes have been unchanged, the new Authentication Key will change every 6 months. This bulletin will be updated with the latest Authentication Key as it becomes available. The new vehicles utilize an Immobilizer
Type “G†or “H†system depending on model:
• G: Vehicles with a turn key ignition switch
• H: Keyless Access with Push-Button Start."
