SOA has initiated a Service Program (WVE-15) to reprogram the Engine Control Module (ECM)
on certain 2008MY Impreza WRX STI vehicles.
Under certain harsh driving patterns, specifically when repeatedly or continuously operating the
engine above the “red-line” (RPM above 6,700), abnormal combustion could occur resulting in
serious internal engine damage in the form of broken piston ring lands. This abnormal
combustion condition is the result of an “over lean” fuel mixture caused by a combination of fuel
cut activation and high turbo boost. To prevent this condition from occurring, Subaru has
developed a modification to the Engine Control Module software logic that will improve
combustion management above “red-line” engine speed. This revised logic will not adversely
affect peak vehicle performance.
General information concerning this Service Program:
• The WVE-15 Service Program Bulletin will be posted on the Techinfo.Subaru.com
website on Thursday, August 14th. The Campaign Bulletin contains additional information
concerning identification of affected vehicles, repair and claim submission procedures.
• On or around August 14, 2008, dealers will be sent affected VIN lists by their Area
Service Office. Dealers are requested to immediately perform this campaign on all
affected vehicles in dealer inventory. Important: Some vehicles that appear on dealer
affected VIN lists may have already been updated by Subaru. Prior to performing
repairs, confirm coverage by using the Vehicle Coverage Inquiry in the Dealer
Communication System (DCS). Vehicles that have been updated by Subaru will
appear "completed" in DCS.
• CDS control numbers for this Service Program are currently available through DCS.
• Subaru will mail owner notification letters on or around August 15, 2008.
Reprogramming software:
The July 2008 SSMIII Software update was released by SOA on August 12, 2008 and contains
the reprogramming pack file needed to complete this Service Program.
Upgrade Version Numbers
• Software: 1.15.33.3
• Interface Box: 1.6.0
• Interface Box CF Card: 1.2.35
Pack File
22611AN351.pak. - 2008MY Impreza STI, ECM To prevent the abnormal combustion during fuel
cut and recovery condition by rev. limiter
