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).
