DATE: 08/15/19
REVISED: 10/12/22

SUBJECT: New Immobilizer Registration Procedures
INTRODUCTION:
This Service Information Bulletin outlines a new required procedure to follow when performing
immobilizer-related repairs on the 2020-22 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.

G and H Types are new. (I-Type is for Canada-spec. only.)

•

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 June 30th, 2022, the Authentication Key has been revised to

previously released information and electronic publications may be updated at any time.

•

Always check for any open recalls or campaigns anytime a vehicle is in for servicing.

•

Always refer to STIS for the latest service information before performing any repairs.
