- 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 icon, which will allow you to access the tutorial information.
SERVICE PROCEDURE
This service procedure will involve reprogramming the ECM with an updated PAK file to correct the deficiency in the OBDII system thermostat monitoring logic.
ECM REPROGRAMMING INSTRUCTIONS
- Verify the status of the "CHECK ENGINE" malfunction indicator light (MIL) located on the vehicle's instrument cluster.
- If no malfunction is indicated, reprogram 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 codes and reprogram the ECM.NOTE: 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 corrections have been made.
Confirm your SSM III contains the applicable SSMIII Flashwrite File Update which includes the following reprogramming PAK files.
VERSION NUMBERS
- Software: 1.35.49.7 or higher
- Interface Box: 1.7.6 or higher

STATE EMISSION TESTING ADVISORY
After ECM reprogramming, the OBD 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 date 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.
CALIFORNIA "VEHICLE EMISSION RECALL - PROOF OF CORRECTION" CERTIFICATE
The California Air Resources Board and the Department of Motor Vehicles Registration/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 California Department of Motor Vehicles may require they provide proof this service program repair has been completed.
Additional certificates are available through the Subaru Claims Helpline at 1-866-782-2782.
CLAIM REIMBURSEMENT AND ENTRY PROCEDURES
Credit to perform this service program will be based on the submission of properly completed repair order information. Dealers may submit claims through Vehicle Claim Entry on Subarunet.com.

Engine Control Module Reprogramming
Vehicles Registered in the States of
CA, CT, MA, MD, ME, NJ, NY, OR, PA, RI, VT, WA
October 2012
Dear Subaru Owner:
We would like to thank you for your selection of a Subaru vehicle. At Subaru, we take pride in our products and are committed to your continued satisfaction.
Subaru has developed a modification to the Engine Control Module software logic to improve the monitoring parameters within the On-Board Diagnostic (OBDII) system for the engine coolant thermostat. This correction ensures that should there be an abnormal condition (i.e., the engine coolant does not reach or maintain the proper operating temperature), the "check engine light" will illuminate. The proper illumination of the "check engine light" is needed to alert you that corrective action may be required.
This software change has no effect on fuel economy or vehicle performance.
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 Engine Control Module software reprogrammed. This will take approximately 30 minutes 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.
In addition, the State of California requires that every vehicle must pass an emission test (SMOG Check) every two years and before it is sold. Without the service we are providing at no charge, your vehicle may not pass this test.
