This Campaign applies to vehicles with motor vehicle registration in the following
states:
2008MY: California, Connecticut, Maine, Massachusetts, New York,

INTRODUCTION
Subaru of America, Inc. has determined vehicles affected by this Service Program require
front catalytic converter replacement and ECM reprogramming.
For vehicles affected by this Service Program, efficiency of the front catalytic converter may
degrade over time. If the catalytic converter efficiency degrades beyond an acceptable level,
the vehicle may be releasing air pollutants which exceed California standards. To correct this
condition, it will be necessary to replace the front catalytic converter and reprogram the ECM
software logic, improving management of the catalytic converter. This software change will not
adversely affect fuel economy or performance of the vehicle.

AFFECTED VEHICLES
• 2008-2009MY 2.5L PZEV Legacy, Outback and Forester
Affected vehicles are identified in the VIN range chart below. NOTE: Not all vehicles in
the VIN ranges are affected. Prior to performing repairs, confirm coverage by using the

DEALER PROGRAM RESPONSIBILITY
Dealers are to promptly perform the applicable service procedures defined in this bulletin to
correct all affected vehicles in their inventory (new, used and demo). Additionally, whenever
a vehicle subject to this Service Program is taken into dealer new or used inventory, or is in
the dealership for service, necessary steps should be taken to ensure the Service Program
correction has been made before selling or releasing the vehicle.
New or used vehicles listed in a Service Program that are in dealer stock must be:
•

Immediately identified

•

Tagged or otherwise marked to prevent their delivery or use prior to repair

•

Repaired in accordance with the repair procedures outlined in this Service Program
Bulletin

PARTS INFORMATION
Catalytic converter replacement will be required.

Due to limited part availability, dealers are requested to order catalytic converter kits as
needed. It is suggested parts be ordered at the time a customer contacts a dealer to schedule an
appointment. This will ensure the necessary parts are available on the day a customer brings
their vehicle in for service.

The kit contains the following components:

SPECIAL TOOLS
Vehicle ECM reprogramming will require the following:

Subaru Diagnostic System (SDS)
•
•
•
•

SOS Toughbook
Subaru Select Monitor Ill (SSMIII Application Software)
Subaru Diagnostic Interface Box (SDI)
USB Data Link Cable and Reprogramming Cable.

Note: If you require assistance with using the Subaru Diagnostic System (SDS), use the
"Help" function, which will allow you to access the tutorial information.

SERVICE PROCEDURE
•

This service procedure involves replacement of the front catalytic converter
assembly and reprogramming of the ECM with updated logic to correct an OBDII
system deficiency.

•

The catalytic converter must be replaced BEFORE reprogramming the ECM.

•

IMPORTANT: Both procedures must be done during the same repair visit.

1. Front Catalytic Converter Replacement
Replace the front catalytic converter following the procedures outlined in the applicable
Subaru Service Manual and any related Technical Service Bulletins. When replacing the
converter, the A/F and 02 sensors should be reused.

Note: To avoid potential damage to the threaded portions of the sensors, allow the converter
to cool down before attempting to remove them. Application of a spray-type penetrating
lubricant to the thread areas and allowing it to soak in for at least a minute or more is
recommended to help ease sensor removal. Be sure to wipe away all excess lubricant. Before
installing the sensors into the replacement converter, application of a small amount of nickle
based anti-seize compound to the sensor threads is also recommended.
2. ECM Reprogramming Instructions
Information regarding ECM reprogramming procedures can be found by accessing the Help
menu located at the top of the Main Menu screen of the SSMIII application.
•

Verify the status of the "CHECK ENGINE" malfunction indicator light (MIL)
located on the vehicle's instrument cluster.

•

If no malfunction is indicated, proceed with reprogramming the ECM .

•

If a malfunction is indicated by the MIL remaining continually "on" or "flashing",
diagnose the cause and perform any necessary repairs. Once repairs have been
completed, clear all DTCs then reprogram the ECM.

NOTES:
• In the event the cause of the check engine light illumination is not covered by
applicable warranties, the cost ofrepairs is the vehicle owner's responsibility.

•

Under no circumstances should the ECM be reprogrammed until the proper
corrections have been made and the catalytic converter replaced.

Confirm your SSM III contains the applicable SSMIII Flash Write File Update which includes
the reprogramming PAK files shown in the chart below. PAK files will be released and
automatically sent electronically to dealer equipment on or prior to the dates indicated in the
"Date Available" column found in the following table.
