applicable Service Manual.

STEP 3: Refer to the applicable Service Manual and review: General Description > Repair Contents>
Action required before & after Battery Disconnect. Additionally, record any stored seat position(s)
before proceeding. Relearn any seat position memory after work is complete. If the power rear gate
(PRG) height has been customized, that position must also be noted and relearned. CAREFULLY
disconnect the ground terminal from the battery sensor.
STEP 4: CAREFULLY Raise the vehicle and locate the ELCM located behind the fuel tank.
STEP 5: CAREFULLY disconnect the ELCM drain tube. Inspect for signs of water or oil.

STEP 6: Connect the vehicle to a recommended power supply. See APPENDIX A for additional
information regarding power supply. Using SSM, perform the Evaporative System Leak Test. Collect
and save all data.

Once the evaporative system leak test is complete, check the DTCs and examine the vacuum value
results. Record the value shown in the row labeled MID: $3C, TID: $C4, and Scaling ID: $FE. This
value should be lower than -0.26 PSI.

Is DTC P2404 stored within the ECM?
NO – Proceed to STEP 7.
YES – Proceed to STEP 8.

STEP 7: Was the vacuum value result observed in STEP 6 found to be lower than -0.26 PSI?
YES – Proceed to STEP 11.
NO – Proceed to STEP 8.

STEP 8: Using SSM, perform the ELCM Pump Active Test for a period of 35 minutes or more. See
APPENDIX A for additional information regarding power supply.

Once the ELCM Pump Active Test has been performed for a period of 35 minutes or more, repeat the
Evaporative System Leak Test outlined in STEP 6. Check the DTCs and the vacuum value results.
Is DTC P2404 stored within the ECM?
NO – Proceed to STEP 9.
YES – Proceed to STEP 10.
STEP 9: Was the vacuum value result observed during the second Evaporative System Leak Test
found to be lower than -0.26 PSI?
YES – Proceed to STEP 11.
NO – Proceed to STEP 10.
STEP 10: Replace the Evaporate Leak Check Module and repeat the Evaporative System Leak Test
outlined in STEP 6. Check the DTCs and the vacuum value results.
Is DTC P2404 stored within the ECM?
NO – Proceed to STEP 11.
YES – Contact Subaru Techline with ability to provide SSM data and the testing results
attained using this bulletin.

STEP 11: Reprogram the ECM following the normal SSM5-R procedure. See APPENDIX A for
addition information regarding power supply.
NOTE: If DTC U0100 is stored after reprogramming, proceed to SECTION C.

SECTION C - DTC U0100 SERVICE PROCEDURE INFORMATION:
During low ambient temperatures, DTC U0100 can become stored within the EyeSight, VDC, etc.
This is caused by the relay contacts within the main relay not operating during low temperatures.
Using SSM, check the Freeze Frame Data (FFD) of DTC U0100. If the ambient air temperature in the
FFD is higher than 0°C (32°F), further diagnosis will be required. If the ambient air temperature in
the FFD is 0°C (32°F) or lower, the fault is cause by insufficient main relay operation. Reprogram the
ECM following the normal SSM5-R procedure. See APPENDIX A for addition information regarding
power supply.
EXAMPLE: EyeSight ECM FFD (22.8 Degrees Celsius is shown)

IMPORTANT: Always note the original Calibration Identification number (CID) the vehicle came in
with on the repair order before reprogramming and, make sure to list the NEW CID for any newlyinstalled programming (as confirmed from the actual control module AFTER installation). The NEW
CID MUST also be noted on the repair order as this information is required for entry in the claim
specific data 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
BATTERY CHARGING INFORMATION
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 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 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.
