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

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.

SPECIAL TOOLS
Vehicle ECM reprogramming will require the following:
Subaru
Diagnostic System (SDS)
• SDS Toughbook
• Subaru
Select Monitor III (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 O2 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 of repairs 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 FlashWrite 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.

Once the applicable Pack File has been identified, proceed with the remainder of the
established ECM reprogramming procedure.
These Pack Files are to be used solely for completion of the WQD-40 Service
Program.
NOTE: Should the ECM become inoperative or un-responsive during the
reprogramming procedure;
1. Disconnect both the positive (+) and negative (-) battery terminals for at least
2 or more seconds.
2. Touch the cable ends together for a few moments, and then re-connect the
terminals to the battery.
3. Start the reprogramming procedure over again from the beginning.
STATE EMISSION TESTING ADVISORY
After ECM reprogramming, the OBDII system’s readiness code monitors will set to
“incomplete”. Normally, the vehicle needs to be driven under a variety of conditions before
the readiness code monitors will indicate “complete”. (See State I/M Program Advisory
Bulletin number 11-120-12, dated 9-20-2012 for details.)
SERVICE PROGRAM IDENTIFICATION LABEL
Type or print the necessary information on a Service Program identification label. The
completed label should be attached to the vehicle’s upper radiator support.
Additional labels are available through the Subaru
Claims Helpline at 1-866-782-2782.

Recall Program requires that all emission related Recall/Campaign or Service Program
repairs be completed before a vehicle registration is renewed. Please provide owners of
vehicles registered in the state of California a completed “Vehicle Emission Recall - Proof of
Correction” certificate. Vehicle owners should be advised to retain this certificate because the

Dear Subaru
Owner:
We would like to thank you for your selection of a 2008-2009 model year Subaru
Legacy,
Outback or Forester vehicle equipped with a 2.5 Liter engine and a California Partial Zero
Emission Vehicle (PZEV) system. At Subaru
, we take pride in our products and are committed
to your continued satisfaction.
Subaru
has determined that the efficiency of your vehicle’s front catalytic converter may
degrade over time. If the catalytic converter efficiency degrades beyond an acceptable level,
your vehicle may be releasing air pollutants that exceed California standards. To correct this
condition, Subaru
will replace the front catalytic converter and reprogram the Engine Control
Module software logic to improve management of the catalytic converter. This software
change will not adversely affect fuel economy or the performance of your vehicle.
WHAT WE ARE ASKING YOU TO DO PROMPTLY
We ask that you schedule an appointment with your Subaru
Dealer as soon as possible to have
your vehicle’s front catalytic converter replaced and Engine Control Module software reprogrammed. Doing so will help ensure your vehicle’s full protection under the emission warranty as failure to do so may be considered a lack of proper maintenance. This will take approximately 1 hour to complete. However, it may be necessary for you to leave your car longer on
the day of your appointment to allow your dealer flexibility in scheduling. Your Subaru
dealer
will perform this modification at no cost to you.
Please present this letter to your Subaru
Dealer on the day of your service appointment.
CALIFORNIA REGISTERED OWNERS
The California Air Resources Board requires that emission related campaigns be completed
prior to California’s vehicle registration renewal process; without this repair, you will not
be able to register your vehicle during your next annual registration. Upon completion of
this campaign, your California dealer will complete and provide you a “Proof of Correction
Certificate.” If required, present the certificate to the California Department of Motor
Vehicles (the “DMV”) when renewing your California registration as proof of campaign
completion. If the DMV does not request the certificate, we recommend that you keep it for
your records.
