STEP 1: Are DTCs P0016, P0017, P0018, or P0019 displayed in the ECM fault memory?
YES – Proceed to STEP 2.
NO – If DTC P0087 is stored, perform the reprogramming procedures outlined in STEP 2
ONLY. The service procedure is finished, no further action is required. For any other
DTCs not mentioned in the bulletin, performe diagnosis and repair as per the applicable
Service Manual.

STEP 2: Reprogram the ECM following the normal FlashWrite procedure.
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 and utilizing 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 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 GR81100 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 SSM5-R 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.

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.

NOTE: 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.
End of procedure for vehicles WITHOUT DTCs P0016, P0017, P0018, or P0019 stored in
the ECM.

STEP 3: Using SSM, read the value the following four data monitor items (ALWAYS Save SSM
Data):
1. VVT Initial Position Learning Value #1
2. VVT Initial Position Learning Value #2
3. VVT EX Initial Position Learning Value #1
4. VVT EX Initial Position Learning Value #2

Are all of the data monitor item values within the acceptable range listed in the table above?
YES - proceed to STEP 5.
NO - proceed to STEP 4.
STEP 4: Perform the procedures outlined in “#7 INSPECTION MODE N” and “#12
INSPECTION MODE T”. Then re-check the threshold values in STEP 3 along with the OBD
MODE test results (*1)
“#7 INSPECTION MODE N” procedure.
Using the applicable Service Manual, refer to: DIAGNOSTICS > ENGINE> Inspection Mode> #7
DRIVE CYCLE N
A. Confirm the battery voltage is 12 Volts or more and the fuel tank is at least half full.
B. Using SSM, clear the fault memory. Prepare the SSM to be kept in the vehicle during the
following road test.

deceleration.
NOTE: Depending on road conditions, an appropriate gear might have to be selected to maintain the
desired engine speed. The vehicle speed is not important as long as the engine speed is within range
during the declaration.
F. In a suitable area, safely bring the vehicle full stop and allow it to idle for 5 minutes.
“#7 INSPECTION MODE N” procedure is complete. Proceed to “#12 INSPECTION MODE T”
procedure.
“#12 INSPECTION MODE T” procedure.

B. Start the engine.
C. Allow the engine to idle for at least 3 minutes.
D. Accelerate the vehicle speed to approximately 37 mph.
E. While maintaining approximately 37 mph, cycle the accelerator from a 0% to 20% opening angle.
Try to keep these cycles within 5 second intervals. Maintain this driving pattern for 20 minutes or
more.
NOTE: It is acceptable to stop the vehicle if needed depending on road/traffic conditions during this
driving pattern.
F. Release the accelerator pedal and brake pedal (and clutch for MT models) and allow the vehicle to
decelerate with any gear shift changes.
G. In a suitable area, safely bring the vehicle full stop and turn off the engine.
