INTRODUCTION: This bulletin announces the availability of reprogramming files to optimize the Engine Control Module (ECM). The new logic will address customer concerns of: • Hard starting in sub-freezing (below 32 degrees Fahrenheit) conditions: Main Relay contacts may freeze in an “open” condition when turning the engine off after a short trip then attempting to restart. • Check Engine light illumination with a DTC P0400 stored in memory: ECM may test the EGR system in error when ambient / intake air temperatures are below freezing. • Surging / vibration condition when using the cruise control in high-altitude areas (FORESTER ONLY): Incorrect amount of throttle compensation when EGR is switched on or off. Operation of the self-shut relay has been changed to minimize the temperature difference inside the relay to prevent condensation / moisture (which may freeze) from occurring. The EGR system parameters have been changed to prevent testing when ambient temperatures do not meet specified criteria. Throttle control software has been optimized to prevent the surging condition. PRODUCTION CHANGE INFORMATION: The new logic was incorporated into production starting with the VINS as listed in the table below: Model Starting VIN Legacy L3016625 Outback L3163560 Impreza 4-Door L3609516 Impreza 5-Door L1720389 Crosstrek LH230394 Forester LH506789 SERVICE BULLETIN ATTENTION: GENERAL MANAGER q PARTS MANAGER q CLAIMS PERSONNEL q SERVICE MANAGER q IMPORTANT – All Service Personnel Should Read and Initial in the boxes provided, right. © 2020 Subaru of America, Inc.

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 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 (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. Bulletin Number: 11-200-20R; Revised: 02/03/21 Page 4 of 5 Continued… • 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: Labor Description Labor Operation # Fail Code Labor Time MFI OBDII ECM Reprogramming A455-288 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 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 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. Bulletin Number: 11-200-20R; Revised: 02/03/21 Page 5 of 5 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.
