Detailed information regarding the SSM5-R reprograming procedures can be found in TSB 14-28-21.
SERVICE PROCEDURE / INFORMATION:
•
PAK Files - Reprogram the TCM following the normal FlashWrite procedure. If P0711
cannot be cleared or is still current after reprogramming, review the additional diagnostic
information found in APPENDIX A.
•
PFC Files - Reprogram the TCM following the normal SSM5-R procedure. Detailed
information regarding the SSM-R reprograming procedures can be found in TSB 14-2821. If P0711 cannot be cleared or is still current after reprogramming, review the additional
diagnostic information found in APPENDIX A.
Subaru of America, Inc. (SOA) highly recommends utilizing either the Subaru Midtronics DCA8000
Dynamic Diagnostic Charging System or the Subaru Midtronics GR8-1100 Diagnostic Battery
Charger to the vehicle in 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 will take 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 (Enhanced Flooded, Flooded, 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 DST-010 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 DST-010 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 14 Volts 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.

•
ALWAYS set the power supply voltage to 13.5 Volts when using Power Supply Mode. NEVER
turn the ignition switch on when charging at voltages 15 Volts or higher.
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
it fully using the DCA-8000 or GR8-1100 before proceeding to reprogram the vehicle 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 or Powertrain Warranty period or covered by a
Subaru Added Security Powertrain, Classic or Gold plan, this repair may be submitted using the
following claim information:
Labor Description

IMPORTANT: The NEW Calibration Identification number (CID) for any newly-installed
programming (as confirmed from the actual control module AFTER installation) MUST be noted on
the repair order as this information is required for claim submission.
NOTE: The PAK file and PFC 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.
