SERVICE PROCEDURE/INFORMATION

2022MY WRX ONLY: Confirm the current software information when programming the Eyesight Control Module is crucial. The system will not check to see if the current software information is installed in the Eyesight Control Module, allowing you to start the reflash with the most up-to-date software installed. Starting the reflash with the most up-to-date software already installed will cause damage to the camera assembly. Confirming that the current software information is not 0F21000131 or 062100072E is imperative. If the software does not have either of those numbers and is effected by either one of the symptoms, proceed with Appendix A for the FlashWrite procedure, as this procedure differs from the standard FlashWrite procedure.

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.

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.

APPENDIX A

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 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.

PREREQUISTS:

Confirm there are no faults within the EyeSight® system. If there are any faults, they must be diagnosed, repaired, and cleared prior to reprogramming. Confirm current software information using Eyesight data display does not show 0F21000131 or 062100072E. If current software numbers are not 0F21000131 or 062100072E please fully exit SSM prior to starting FlashWrite.
Apply the Electronic Parking Brake (EPB). Switch the ignition switch to the "ON" position (engine off). Using the gear selector lever, set the vehicle in the Neutral (N) range. Wait at least 5 minutes after complete.
CRITICAL:
- If the gear selector is in the Park (P) range, it is possible for the ignition switch to turn off automatically while reprogramming after approximately 60 minutes. This will cause the reprogramming procedure to fail.
- DO NOT operate SSM during reprograming.
- DO NOT have the engine running during reprogramming.
- You must recheck the software information after every attempted reflash. If 0F21000131 or 062100072E are displayed, the reflash was successful. If the software information is different, please reattempt the procedure up to three times.
- If the unsuccessful reprogramming attempts are made, the EyeSight Camera Stereo Assembly will require replacement as per the applicable Service Manual. Refer to the part information on page #2.
Confirm the PC being use for reprogramming is connected to a known good power source. Turn off any screen saver settings. Make sure the PC is not in power saving mode and is set to the normal power mode.
Confirm all electrical loads are switched off such as climate control, seat heater, audio system, etc.
Connect a Midtronics DCA-800 or GR8-100 battery charger to the vehicle, utilize the Power Supply Mode feature to supply a stable 13.5 volts.

NOTE:

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.
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.

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.

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.
