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.
Confirm your SSM III contains the applicable SSM III 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
^ Interface Box CF Card: 1.7.0 or higher
The chart indicates the applicable PAK files and date available.
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.
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.
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.
