the access key on their person can operate the Keyless Access System if the key is within range. The
update ensures that only the door nearest to the access key can operate the keyless entry system.

SERVICE PROCEDURE / INFORMATION:
REMINDER: Customer satisfaction and retention starts with performing quality repairs.
IMPORTANT: Due to the duration of the reprogramming of the Keyless Access Control Module, a
Subaru approved Denso SSM cable is STRONGLY recommended. Cables from other manufacturers
may not meet data transfer rate and interference shielding requirements to ensure error-free data
transmission during reprogramming.
CAUTION: Ensure the Midtronics GR8 / Midtronics DCA-8000 set to Power Supply Mode is
connected to the vehicle, the parking brake is engaged, ignition is in the “ON” position, the engine
is OFF, the shift selector in NEUTRAL and the wheels are blocked. This must be done to ensure the
power supplied to the Keyless Access Control Module is not turned off. If this step is not performed,
the Keyless Access Control Module will power down the Keyless Access Control Module during the
reflash, and the reprogramming will fail, resulting in irreparable damage.
For vehicles with PAK file availability reprogram the Keyless Access Control Module following the
normal FlashWrite procedure once the vehicle is confirmed to be in NEUTRAL, the DCA-8000 is set
to power supply mode and connected to the vehicle’s battery, and a charger is connected to the laptop.
For vehicles with PFC files availability reprogram the Keyless Access Control Module following the
standard SSM5-R procedure once the vehicle is confirmed to be in NEUTRAL, the DCA-8000 is set
to power supply mode and connected to the vehicle’s battery, and a charger is connected to the laptop.
Detailed information regarding the SSM5-R reprograming procedures can be found in TSB 14-2821R.

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 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 GR8-1100
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 SSM5-R 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.
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, 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) / ROMID the
vehicle came in with on the repair order before reprogramming and, make sure to list the NEW CID /
ROMID for any newly installed programming (as confirmed from the actual control module AFTER
installation). The NEW CID / ROMID MUST also be noted on the repair order as this information is
required for entry in the Claim Specific Detail field during claim submission. These numbers can be
read using SSM5-R.
NOTE: The 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 SSM5-R. If a
newer CID is shown as available in SSM5-R, 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.
