STEP 1: Are DTCs P0016, P0017, P0018, or P0019 displayed in the ECM fault memory?
YES – Proceed to STEP 2.
NO – If DTC P0087 is stored, perform the reprogramming procedures outlined in STEP 2
ONLY. The service procedure is finished, no further action is required. For any other
DTCs not mentioned in the bulletin, performe diagnosis and repair as per the applicable
Service Manual.
STEP 2: Reprogram the ECM following the normal Flashwrite or SSM5-R procedure. Detailed
information regarding the SSM5-R reprograming procedures can be found in TSB 14-28-21R.
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 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 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.

Bulletin Number: 09-112-23; Date: 01/04/24
Page 5 of 14
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.
End of procedure for vehicles WITHOUT DTCs P0016, P0017, P0018, or P0019 stored in
the ECM.
STEP 3: Start the vehicle and allow to idle. Using the SSM, read the value the following four data monitor items

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 Miscellaneous 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.
For Situations Continuing after Step 4 or 5 of the Work Procedure.
When further Diagnosis and repairs are needed an additional job line / repair claim can be
submitted. Please refer to the Subaru Labor Time Guide for warranty time and coverage. Below is a
possible EXAMPLE.
