SERVICE PROCEDURE / INFORMATION
VERY IMPORTANT: Whenever replacing a CVT assembly with either a new OR remanufactured unit, the TCM MUST be reprogrammed with the applicable pack file from the table above as part of the repair procedure before releasing the vehicle.
SOA now highly recommends connecting the Midtronics GR8 Diagnostic Battery Charger to the vehicle and utilizing the Power Supply Mode feature anytime a vehicle control module is being reprogrammed. Once the GR8 is connected to the vehicle, as long as the battery is fully charged, it takes less than 3 minutes to boot-up the charger, select the Power Supply Mode, and have the battery voltage stabilized and ready for reprogramming.
VERY IMPORTANT: This information is applicable to the Midtronics GR8 Diagnostic Battery Charger ONLY. It does not apply to any other brand / type of “generic” battery charger whatsoever. ONLY the GR8 and its Power Supply Mode feature has been tested and approved by Subaru of America, Inc. (SOA).
- If the GR8 indicates the vehicle’s battery must be charged, charge the battery using the GR8 before proceeding to reprogram the vehicle while using the Power Supply Mode.
- Control module failures as a result of battery discharge during reprogramming are not a matter for warranty. Should any DTCs reset after the reprogramming update is performed, diagnose per the procedure outlined in the applicable Service Manual.
WARRANTY / CLAIM INFORMATION
For vehicles within the Basic New Car Limited and / or Emissions Warranty period, this repair may be submitted using the following claim information:
NOTE: The pack file listings provided in this bulletin are the latest available at the time of publishing. Updates are often released thereafter without revision to the original bulletin. For this reason, it is critical to always have the latest version of Select Monitor III software installed on your system. You can confirm if a later version is available by entering the CID listed in this bulletin into FlashWrite. If a newer CID is shown as available in FlashWrite, reprogram using that file.
REMINDER: SOA strongly discourages the printing and/or local storage of service information as previously released information and electronic publications may be updated at any time.
- Always refer to STIS for the latest service information before performing any repairs.
Subaru reprogramming files using a generic (non-OEM) SAEJ2534 pass-thru vehicle programming device are available by contacting Service Technical Information Company toll free at 1-866-428-2278. The cost for the CD-ROM with all reprogramming files is $75.00 plus S/H and applicable state tax. Files will be updated four (4) times per year, in CD-ROM format, with all available reprogramming service information at the same above offered cost. Authorized Subaru Dealers are provided the same reprogramming information.
Before purchasing, the reprogramming details can be found in the following Reprogramming J-2534 Files chart. Click the link to view the PDF chart.
Subaru J2534 Reprogramming software meets the latest available J2534-1 specification. Our Reprogramming J2534 Files chart does not specify the Calibration Identification Number (CID); however, this information is included in our offered CD-Rom.
Note: The ECM or TCM being reprogrammed may already contain some or all of the reprogramming files listed in the Reprogramming J2534 Files chart shown by release date. It is possible to damage the vehicles ECM/TCM during the reprogramming event. Once the reprogramming process has started, it is recommended not to interrupt the process until the event is completed. If you experience any problems, please contact your scan tool maker for further instructions.
No. Subaru has no reprogramming capability for model years 1996-1998. Starting with our 1999 model year, please see our Reprogramming Pre-J2534 Files chart for affected model reprogramming information.
