INTRODUCTION:

This bulletin announces availability of reprogramming files to optimize the Engine Control Module

(ECM).  These new files address concerns of the check engine light coming on and setting a DTC P0400: EGR “A” FLOW. The DTC can set if the ECM tests the EGR system when ambient / intake air temperatures are below freezing.

PACK FILE APPLICABILITY:

NOTE:  These files are included in the January 2020 SSM software update.

SERVICE PROCEDURE:

REMINDER:  Customer satisfaction and retention starts with  performing quality repairs.

• Reprogram the ECM following the normal FlashWrite procedure.

SERVICE PROCEDURE / INFORMATION:

Subaru of America, Inc. (SOA) highly recommends connecting either the Subaru Midtronics DCA8000 Dynamic Diagnostic Charging System or the Subaru Midtronics GR8-1100 Diagnostic Battery Charger to the vehicle and utilizing the Power Supply Mode feature anytime a vehicle control module is being reprogrammed.

Once the Midtronics charger is connected to the vehicle, if the battery is fully charged, it takes less than three (3) minutes to boot-up the charger, select the Power Supply Mode, and have the battery voltage stabilized and ready for reprogramming.

NOTES:

• For instructions on using the power supply mode, reference the applicable User Manual for the Midtronics DCA-8000 Dynamic Diagnostic Charging System and the Midtronics GR81100 Diagnostic Battery Charger on STIS.
• Confirm all electrical loads such as lights, audio, HVAC, seat heaters, and rear defroster are all switched OFF before setting up the charger for Power Supply Mode.
• Select the correct battery type (Flooded, EFB, Gel, AGM or AGM Spiral).
• Input the CCA which matches the vehicle’s battery. NOTE: OE and replacement batteries have different CCA ratings.  Always confirm the battery’s CCA rating before proceeding.
• If using a DCA-8000 Dynamic Diagnostic Charging System, set the power supply voltage to 13.5 volts.
• DO NOT connect the DST-i or SDI until the Power Supply mode function has completed its battery test mode and the Charging Voltage has dropped to and shows a steady 13.5 Volts on the display.
• Once Power Supply Mode reaches a steady 13.5 volts, connect the DST-i or SDI to the OBD connector and proceed with initiating the normal FlashWrite 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 is made.

VERY IMPORTANT:

This information is applicable to the Subaru Midtronics DCA-8000 Dynamic Diagnostic Charging System and the Subaru Midtronics GR8-1100 Diagnostic Battery Charger ONLY.  It does not apply to any other brand / type of “generic” battery charger whatsoever.  ONLY the DCA-8000 and the GR8-1100 and their Power Supply Mode feature have been tested and approved by SOA.

REMINDER:  If the DCA-8000 or GR8-1100 indicates the vehicle’s battery must be charged, charge the battery fully before proceeding to reprogram the vehicle while using the Power Supply Mode.

NOTE:  Control module failures resulting from 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, an applicable Emission Warranty period or covered by an active Subaru Added Security Classic or Gold plan, this repair may be submitted using the following claim information:

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 newly-installed 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 entry in the Miscellaneous Detail field during claim submission.

NOTE:  The pak 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.

Reprogramming

What J2534 reprogramming capabilities are available?

(4a) 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/TCMduring 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.

(4b) 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.
