Continued... Bulletin Number: WRK-21R; Revised: 07/18/22 Page 17 of 25 Appendix A STEP A-1: Subaru of America, Inc. (SOA) highly recommends connecting either the Subaru Midtronics DCA-8000 Dynamic Diagnostic Charging System or the Subaru Midtronics GR8-100 Diagnostic Battery Charger to the vehicle and utilizing the Power Supply Mode feature to supply a stable 13.5 volts 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. • If using a DCA-8000 Dynamic Diagnostic Charging System, set the power supply voltage to 13.5 volts. • DO NOT connect the DST-I, DST 010, 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, DST 010, 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 GR81100 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 it fully using the DCA-8000 or GR8-1100 before proceeding to reprogram the vehicle using the Power Supply Mode. Continued... Bulletin Number: WRK-21R; Revised: 07/18/22 Page 18 of 25 NOTES: • 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. • IMPORTANT: The FINAL Calibration Identification number (CID) for the FINAL programming (not the testing file) MUST be noted on the repair order as this information is required for claim submission. • The testing and FINAL pack 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. • AT Learning Procedure is ONLY required with CVT replacement. STEP A-2: (ONLY IF THE CVT HAS BEEN REPLACED) Using the SSM4, clear the AT Learning Data using the following procedure: • Start > Diagnosis > Vehicle Selection > Each System > Transmission > Work Support > Clear AT Learning Data. • Click “YES” and when “Execute Clear AT Learning” is displayed, click “YES” again. • Turn the ignition OFF, wait at LEAST 30 seconds then turn the ignition back ON. At this point, the AT Temp light will start blinking; 4 times in 2 seconds to signify the Clear AT Learning procedure has completed successfully. If the AT Temp light does not flash as described, repeat Step 2 again from the beginning. Continued...

Subaru of America, Inc. (Subaru) has decided that a defect, which relates to motor vehicle safety, exists in certain 2019-2020 model year Ascent vehicles and certain 2020 Legacy and Outback vehicles. You received this notice because our records indicate that you currently own one of these vehicles. This recall replaces Subaru’s previous WUV-07 recall issued in January 2020 for certain 2019 model year Ascent vehicles. Vehicles affected by the previous recall must return to complete the WRK-21 recall repair, even if the previous recall repair was complete. DESCRIPTION OF THE DEFECT AND SAFETY RISK Due to a programming error in the transmission control unit (TCU), the drive chain may slip, resulting in breakage of the chain guide. If the drive chain guide breaks, resulting fragments could inhibit the shift select mechanism. If the vehicle continues operation with the drive chain slipping, over time the drive chain could break. If the drive chain breaks while the vehicle is in motion, the vehicle may experience a loss of motive power, increasing the risk of a crash. WHAT YOU SHOULD DO As mentioned above, vehicles affected by the previous recall must return to complete the WRK-21 recall repair, even if the previous recall repair was completed. Subaru is in the process of acquiring the tools and reprogramming files necessary to perform this repair and expects to have a sufficient supply available in May. Once the repair is available, Subaru will contact you again by mail advising you to proceed with scheduling an appointment with your Subaru retailer (dealer). WHAT SUBARU WILL DO Once the tools and reprogramming files are available to perform this repair, your Subaru retailer will reprogram the TCU. The historical TCU data will be analyzed for chain slip characteristics and the chain guide will be visually inspected. If the vehicle is confirmed to have experienced drive chain slip or if the chain guide is damaged, the transmission assembly will be replaced. All remedy repairs necessary will be completed at no cost to you. Continued...
