SERVICE PROCEDURE / INFORMATION:
Reprogram the ECM following the normal FlashWrite procedure.
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 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 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.

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.
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 GR81100 and their Power Supply Mode feature have been tested and approved by SOA.
WARRANTY / CLAIM INFORMATION:
For vehicles within the Federal Emissions Extended Defect and Performance Warranty period, this
repair may be submitted using the following claim information:
Labor Description
Labor Operation #
Fail Code
Labor Time
ECM REPROGRAMMING FOR DTC P0011
& P0021
A451-086
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 entry in the
Miscellaneous Detail field during claim submission.
NOTE: The PFC and 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.
