Reprogramming File Availability for Startability

NUMBER: 11-199-20
DATE: 02/11/20
INTRODUCTION:
This bulletin announces availability of reprogramming files to optimize the Engine Control Module
(ECM). The new logic will address isolated concerns of a hard start condition occurring in cold
weather (+10 degrees Fahrenheit or lower) and / or high-altitude areas. When this scenario occurs,
the A/F learning control values move toward lean. In addition, if the condition were to occur on an
engine with relatively high mechanical friction (typically, an engine with low mileage), a hard start
condition may result.
PRODUCTION CHANGE INFORMATION:
This bulletin will be updated with the starting VINS for these logic changes when they become
available.

NOTE: All these reprogramming files were 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 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.
