INTRODUCTION:

This Service Information Bulletin outlines a new required procedure to follow when performing immobilizer-related repairs on the all-new 2020-24 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 approximately 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.

 

SERVICE PROCEDURE / INFORMATION:

REMINDER:  Customer satisfaction and retention starts with performing quality repairs.

• After connecting the SSM4 to the vehicle and starting the application, from the Main Menu, select Immobilizer etc. registration, select the Vehicle then Immobilizer Type and Confirmed.

 

• When the vehicle utilizes either a G or H -Type system, an Authentication Key is required to perform any of the immobilizer-related functions listed in the menu shown below.

 

• Currently, for all other models, the immobilizer registration process is unchanged.

• For 2020MY Legacy and Outback with a G or H -Type system, the Server Connection screen shown below will be displayed. Input the current Authentication Key and select “Connection”.

 

IMPORTANT NOTE: As of December 30th, 2023, the Authentication Key has been revised to 6P4TXWMC.

 

• Detailed instructions for performing all immobilizer-related functions can now be found on STIS under the Other/Miscellaneous Publication Type: “20MY Registration Manual for Immobilizer” or by searching Document Code: S1108BE.
