Continued… INTRODUCTION: This bulletin announces reprogramming file availability to optimize the Body Integrated Unit (BIU) and address the following customer concerns: • If a customer exits the vehicle with the ignition OFF, all the doors closed and leaves the hazard warning switch ON, after about 75 seconds, the access key (models with push-button start) or the RKE fob buttons (models with key start) will not lock or unlock the doors. • The power driver seat position control buttons are inoperative when opening the driver’s door after the push-button ignition switch is OFF. • The power rear gate (PRG) is inoperative when using the dashboard control buttons or the access key button when the push-button ignition switch is OFF and all doors are closed. PRODUCTION CHANGE INFORMATION: This new logic was incorporated into production starting with the following VINs: • Legacy: J*016913 • Outback: J*243738 PACK FILE APPLICABILITY: Model PAK File Name Target Unit Part Number New BIU Part Number Decryption Keyword 2018MY LEGACY / OUTBACK W/ PUSH-BUTTON START 82201AL30B_smt.pak 82201AL30B 82201AL30C 3DFBAEE1 2018MY LEGACY / OUTBACK KEY START MODELS 82201AL31B_key.pak 82201AL31B 82201AL31C C574CBA5 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. ©2017 Subaru of America, Inc.

Bulletin Number: 07-124-17R; Revised 08/17/20 Page 2 of 3 SERVICE PROCEDURE / INFORMATION: NOTES: • The October 2017 (or newer) FlashWrite 2 software version is required to perform this reprogramming. • When performing this reprogramming procedure, after checking the Vehicle Spec box, select “BIU” from the CPU drop-down list. • Proceed with reprogramming the BIU following the normal FlashWrite procedure. Subaru of America, Inc. (SOA) highly recommends connecting the Subaru Midtronics GR8 Diagnostic Battery Charger to the vehicle and utilizing the Power Supply Mode feature anytime a vehicle control module is being reprogrammed. Follow the procedure as outlined in document GR8- 1100 on STIS for use of the GR8’s Power Supply Mode: • Confirm all electrical loads such as lights, audio, HVAC, seat heaters, and rear defroster are all switched OFF before setting up for Power Supply Mode. • Select the correct battery type (Flooded, AGM or AGM Spiral). • Select the CCA which matches the vehicle’s battery (NOTE: OE and replacement batteries have different CCA ratings. Always confirm the battery rating before proceeding.) • If the “Charge Battery” WARNING appears, the battery MUST be charged before attempting reprogramming. • DO NOT connect the DSTi or SDI until the GR8 Power Supply mode has completed its battery test mode and the Charging Voltage has dropped to a steady 13.5 Volts on the display. • If the GR8 “beeps” or the Status Light flashes, a diagnostic charge should be performed on the battery before proceeding further. • Once Power Supply Mode reaches a steady 13.5 volts, connect the DSTi or SDI to the OBD connector and initiate the 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. IMPORTANT: This information is applicable to the Midtronics GR8 Diagnostic Battery Charger ONLY. It does not apply to any other brand / type of “generic” battery charger whatsoever. ONLY the GR8 and its Power Supply Mode feature has been tested and approved by SOA. Once the GR8 is connected to the vehicle, as long as the battery is fully charged, it takes less than 3 minutes to boot-up the charger, select Power Supply Mode, and have the battery voltage stabilized and ready for reprogramming. REMINDER: If the GR8 indicates the vehicle’s battery must be charged, charge the battery using the GR8 before proceeding to reprogram the vehicle. NOTE: Control module failures as a result of 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.

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.
