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 No repair parts are needed to perform this procedure. 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 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. 1. ECM Reprogramming Instructions 1. Verify the status of the “CHECK ENGINE” malfunction indicator light (MIL) located on the vehicle’s instrument cluster. 2. If no malfunction is indicated, reprogram the ECM. 3. 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. Bulletin Number: WQC-39; Date: October 2012 (Revised 11/30/12) Page 4 Continued… Important reminders about reprogramming the ECM on all vehicles: • Follow ECM reprogramming procedures and precautions found in the applicable Subaru service manual. • Start the engine and allow it to run until base idle speed is achieved. The reprogramming procedure must be performed within 1 hour. • Should the ECM become inoperative or un-responsive while performing the reprogramming procedure, disconnect both the positive (+) and negative (-) battery terminals for at least 2 or more seconds. Touch the cable ends together for a few moments. Re-connect the terminals to the battery. Begin the normal reprogramming procedure for a second attempt.

Box 6000 Cherry Hill, NJ 08034-6000 www.subaru.com Service Program WQC-39 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 (OBDll) 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.

Important Information Regarding Service Program Bulletin WQC-39 TO: SDC, EST, CEN, WST and SNE FROM: Subaru of America, INC. DEPARTMENT: Service DATE: 11/14/2012 CATEGORY: Show in all Categories It has come to our attention some 2011 model year (MY) Legacy and Outback model vehicles affected by the WQC-39 Service Program may not require the ECM reprogramming update to correct the thermostat monitoring logic. As a result, there may be instances where a customer brings their vehicle into your Service Department for the WQC-39 ECM reprogramming procedure and it cannot be completed as indicated in the campaign bulletin. In those cases, when the Technician selects the appropriate file for reprogramming as listed in the Campaign Bulletin, the Select Monitor III returns a message stating the “ECU is not suitable for reprogramming” as shown in the illustration below. If your Technician receives this “not suitable” message, we request the following steps be completed: 1. The Technician must confirm the Calibration Identification (CID) number of the ECM is included on the following “Ineligible” CID list below. 2. The Technician should then review the list to see if “Another Update” is available. 3. If “Another Update” is available, the Technician should install the ECM update and a WARRANTY CLAIM should be filed as indicated below. (The WQC-39 campaign should NOT be claimed in this case. It will be closed by SOA based upon your Warranty Claim submission.) 4. If there are no other updates for the vehicle as shown below, a WARRANTY CLAIM should be filed as indicated below. (The WQC-39 campaign should NOT be claimed in this case. It will be closed by SOA based upon your Warranty Claim submission.) “Ineligible” CID for WQC39 (ECU part# level) Eligible for “Another Update”?

For a very small number of vehicles, this additional scenario may apply: if a customer presents a letter indicating they have an open WQC-39 Campaign open on their vehicle and your Vehicle Coverage Inquiry check shows no open or completed WQC-39 campaign, the following steps should be followed: 1. The Technician must check FlashWrite for any update which the vehicle ECM may be eligible for and install it. 2. Use the coding below to claim for this check and / or installation of any available ECM update. IMPORTANT NOTE: Whether the ECM has been updated or not, when submitting your warranty claim, be sure to include in the Claim Comments section the ECM’s final CID number displayed by the SSMIII the car leaves your dealership with.

Subarunet Announcement To: All Subaru Dealers From: Subaru of America, Inc. Date: October 26, 2012 Subject: Subaru Service Program WQC-39: ECM Reprogramming 2011-2012MY All Models & 2013 BRZ; Only Vehicles Registered in California Emission States: CA, CT, MA, MD, ME, NJ, NY, OR, PA, RI, VT, and WA. Subaru of America, Inc. has initiated a Service Program to reprogram the Engine Control Module on all 2011 and 2012 models within specific VIN ranges and certain 2013 BRZ models. This program only involves vehicles that are registered in the California emission states (CA, CT, MA, MD, ME, NJ, NY, OR, PA, RI, VT, and WA). A modification to the ECM software logic has been developed to improve the monitoring parameters within the On-Board Diagnostic (OBDll) 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 the driver that corrective action may be required. ECM reprogramming PAK files will not be available for all models at the time this Service Program is initially released. PAK files will be available in accordance with the schedule found on page 4 of the WQC-39 bulletin.
