APPENDIX A
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 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:
1. Confirm there are no faults within the EyeSight® system. If there are any faults, they must
be diagnosed, repaired, and cleared prior to reprogramming. Fully exit SSM prior to starting
FlashWrite
2. 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.
3. 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.
4. Confirm all electrical loads are switched off such as climate control, seat heater, audio system,
etc.
5. 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.
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
allnswitched 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 GR81100 and their Power Supply Mode feature have been tested and approved by SOA.
