SERVICE BULLETIN APPLICABILITY: 2020-24MY Legacy & Outback 2.4L NUMBER: 09-117-24 2019-24MY Ascent DATE: 04/09/24 SUBJECT: Engine Not Cranking During Low Ambient Temperatures DTC P0890 - TCM Power Relay Sense Circuit Low INTRODUCTION: This bulletin announces the availability of new reprogramming files developed to address cases of DTC P0890 (TCM Power Relay Sense Circuit Low) detected by the Engine Control Module (ECM). When the engine is shut off after a short distance drive when the ambient temperature is 32°f (0°C) or below, Moisture may develop inside the starter relay and cause the internal contacts to stick or freeze. The new software allows the relay contacts to be cycled periodically to prevent any sticking or freezing of the contact points. If this situation is reported by a customer and/or DTC P0890 is stored in the ECM fault memory, perform the reprogramming procedure outlined below. 2020-2022 LEGACY AND OUTBACK PAK FILE APPLICABILITY: MY 20 21 22 22 Model LEGACY & OUTBACK LEGACY & OUTBACK LEGACY & OUTBACK OUTBACK Wilderness Specification 2.4L Turbo 2.4L Turbo 2.4L Turbo 2.4L Turbo File Description Old Part # Decryption Keyword New CID 22765AM978.pk2 22765AM970 22765AM971 22765AM972 22765AM973 22765AM974 22765AM975 22765AM976 22765AM977 68DC9050 LG7D901B00G 22765AR246.pk2 22765AR240 22765AR241 22765AR242 22765AR243 22765AR244 22765AR245 F3C7F721 LG7F601F00G 22765AR994.pk2 22765AR990 22765AR991 22765AR992 22765AR993 8990873C LG7G501G00G 22765AR254.pk2 22765AR250 22765AR251 22765AR252 22765AR253 BF3BAD7C LG7G501H00G CAUTION: VEHICLE SERVICING PERFORMED BY UNTRAINED PERSONS COULD RESULT IN SERIOUS INJURY TO THOSE PERSONS OR TO OTHERS.

Bulletin Number: 09-117-24; Date: 04/09/24 Page 2 of 4 2023-2024 ASCENT PFC FILE AVAILABILITY: MY Model Specification File Description Old Part # New CID 23 ASCENT 2.4L Turbo 22765AS633.pfc 22765AS630 22765AS631 22765AS632 LHBK301Y00G 24 ASCENT 2.4L Turbo 22765AU261.pfc 22765AU260 LHBP201A00G SERVICE PROCEDURE / INFORMATION: • 2019-22MY: Reprogram the ECM following the normal FlashWrite procedure. • 2023-24MY: Reprogram the VDC Control Module following the normal SSM5-R procedure. Detailed information regarding the SSM5-R reprograming procedures can be found in TSB 1428-21R. 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 itsbattery 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. Continued... Bulletin Number: 09-117-24; Date: 04/09/24 Page 3 of 4 • 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. WARRANTY / CLAIM INFORMATION: For vehicles within the Basic New Car Limited Warranty period, 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. 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.
