SERVICE BULLETIN
APPLICABILITY:
2015-19MY Legacy & Outback 3.6L
SUBJECT:
Reprogramming Files for DTC P0116
NUMBER:
02-195-26
DATE:
06/01/26
INTRODUCTION:
This bulletin announces the availability of reprogramming files for the Engine Control Module
(ECM) for certain vehicles equipped with 3.6L engines. The updated logic has been developed to
address Diagnostic Trouble Code (DTC) P0116 – Engine Coolant Temperature Sensor 1 Circuit
Range/Performance, which may be triggered when the vehicle is equipped with a block heater.
Under specific conditions, this DTC may set while the block heater is in use due to cool coolant
circulating immediately after startup. This rapid change in coolant temperature can cause the sensor
reading to drop quickly, resulting in the DTC being set.
If DTC P0116 is detected by the ECM, follow the reprogramming procedure outlined in this bulletin.

SERVICE PROCEDURE / INFORMATION:
REMINDER: Customer satisfaction and retention starts with performing quality repairs.
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 Warranty, For vehicles registered in
SULEV states, California Emissions Extended Defect Warranty coverage applies, or covered by an
active Subaru Added Security Classic or Gold plan, this repair may be submitted using the following

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 SSM4-R
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.
