SERVICE PROCEDURE / INFORMATION:
Step 1: Reprogram the TCM using the SSM4 following the normal FlashWrite procedure.
NOTES:
SOA now highly recommends connecting the Midtronics GR8 Diagnostic Battery Charger to the
vehicle and utilizing the Power Supply Mode feature anytime a vehicle control module is being
reprogrammed. Once the GR8 is connected to the vehicle and as long as the battery is fully
charged, it takes less than 3 minutes to boot-up the charger, select the Power Supply Mode, and
have the battery voltage stabilized and ready for reprogramming.
VERY 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 Subaru of America, Inc. (SOA).
•
If the GR8 indicates the vehicle’s battery must be charged, charge the battery using the GR8
before proceeding to reprogram the vehicle while using the Power Supply Mode.
•
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.
Step 2: 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.
Step 3: Using the SSM4, perform the AT Learning Control following the procedure outlined Service
Manual excerpt supplied below:
1. PREPARATION FOR LEARNING:
1. Warm up or cool down until the ATF temperature displayed on the Subaru Select Monitor is
40-65°C (104-149°F).
2. After stopping the vehicle, shift the select lever to “P” range.
3. Fully apply the parking brake.
4. Raise the vehicle.
CAUTION:
While working, be sure to keep the lower edge of the tires 30 cm or more above the ground

the beginning.
•
If the message «Execute AT learning again after fixing troubles of the vehicle» appears
during learning, select [OK] and display the DTC list. After repairing the locations
