Service Procedure / Information:
Subaru of America, Inc. (SOA) highly recommends connecting the Subaru Midtronics GR8 Diagnostic Battery Charger to the vehicle and utilizing the Power Supply Mode feature anytime a vehicle control module is being reprogrammed. Follow the procedure as outlined in document GR8-1100 on STIS for use of the GR8’s Power Supply Mode:
- Confirm all electrical loads such as lights, audio, HVAC, seat heaters, and rear defroster are all switched OFF before setting up for Power Supply Mode.
- Select the correct battery type (Flooded, AGM or AGM Spiral).
- Select the CCA which matches the vehicle’s battery (NOTE: OE and replacement batteries have different CCA ratings. Always confirm the battery rating before proceeding.)
- If the “Charge Battery” WARNING appears, the battery MUST be charged before attempting reprogramming.
- DO NOT connect the DSTi or SDI until the GR8 Power Supply mode has completed its battery test mode and the Charging Voltage has dropped to a steady 13.5 Volts on the display.
- If the GR8 “beeps” or the Status Light flashes, a diagnostic charge should be performed on the battery before proceeding further.
- Once Power Supply Mode reaches a steady 13.5 volts, connect the DSTi or SDI to the OBD connector and initiate the reprogramming process.
- Amperage will fluctuate based upon the vehicle’s demand for power. NOTE: If the voltage rises beyond 14V while programming is in process, the procedure will abort. This can indicate a need to test or charge the vehicle battery before any further attempt at programming.
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 SOA.
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 Power Supply Mode, and have the battery voltage stabilized and ready for reprogramming.
REMINDER: If the GR8 indicates the vehicle’s battery must be charged, charge the battery using the GR8 before proceeding to reprogram the vehicle.
NOTE: 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:
| Labor Description | Labor Operation # |
Fail Code |
Labor Time |
|---|---|---|---|
| MFI OBDII ECM Reprogramming | A455-288 | UPG-48 | 0.4 |
IMPORTANT: Always note the original Calibration Identification number (CID) the vehicle came in with on the repair order before reprogramming and, make sure to list the NEW CID for any newlyinstalled programming (as confirmed from the actual control module AFTER installation). The NEW CID MUST also be noted on the repair order as this information is required for claim submission.
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 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.
IMPORTANT REMINDERS:
- 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 check for any open recalls or campaigns anytime a vehicle is in for servicing.
- Always refer to STIS for the latest service information before performing any repairs.
J2534 Reprogramming
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.
Are all pre-2004MY Subaru vehicles compatible with J2534?
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.
Both pre-J2534 reprogramming and J2534 pass thru reprogramming files are included in the offered HDS kit software for aftermarket service provider application.
