P0890 TCM Power Relay Sense Circuit
P05A0 Active Grille Air Shutter “A” Stuck on
Low DTC P015A & P015B / Delayed O2 Sensor Response
INTRODUCTION:
This bulletin announces availability of new reprograming files for the Engine Control Module
(ECM). These files have been developed to address concerns of the starter motor not operating
and/or illumination of the engine warning lamp. This concern may occur under any of the four
driving scenarios outlined below. It is IMPORTANT to fully review the details below to
accurately confirm the concern and perform the reprogramming procedure when necessary.
DESCRIPTIONS OF CONCERN:
Scenario A:
While attempting a restart after a short drive cycle in low ambient temperatures (less than 0 Degrees Celsius / 32 Degrees Fahrenheit), the starter motor may not operate. DTC P0890 (TCM
Power Relay Sense Circuit Low) will likely be stored in the ECM under this condition. Condensed
moisture in the ignition relay can cause the contact points to freeze under these conditions. The
new logic enhances the relay self-shutdown program, eliminating the possibility of frozen relay
contacts.
Scenario B:
DTC P05A0 (Active Grille Air Shutter “A” Stuck On) may be stored in the ECM when the vehicle is driven in low ambient temperatures (less than 0 Degrees Celsius / 32 Degrees Fahrenheit)
and/or harsh weather including snow and freezing rain. This is caused by an inaccurate freezing
estimation of the Active Grille Shutter (AGS) by the ECM. The new logic optimizes the freezing
estimation program within the ECM.
Scenario C:
P015A (A/F /02 Sensor Delayed Response - Rich to Lean Bank 1 Sensor 1) & P015B (A/F /02
Sensor Delayed Response - Rich to Lean Bank 1 Sensor 1) may set when stabbing acceleration
(ON then quickly OFF the accelerator) and similar braking are performed repeatedly such as in
stop and go driving while the engine is warming up.
CAUTION: VEHICLE SERVICING PERFORMED BY UNTRAINED PERSONS COULD
RESULT IN SERIOUS INJURY TO THOSE PERSONS OR TO OTHERS.
Subaru Service Bulletins are intended for use by professional technicians ONLY. They
are written to inform those technicians of conditions that may occur in some vehicles,
or to provide information that could assist in the proper servicing of the vehicle. Properly
trained technicians have the equipment, tools, safety instructions, and know-how to
do the job correctly and safely. If a condition is described, DO NOT assume that this
Service Bulletin applies to your vehicle, or that your vehicle will have that condition.
Subaru of America, Inc. is
ISO 14001 Compliant
ISO 14001 is the international standard for
excellence in Environmental Management
Systems. Please recycle or dispose of
automotive products in a manner that is friendly
to our environment and in accordance with all
local, state and federal laws and regulations.

Page 1 of 8
Scenario D:
A hesitation and/or lack or power may be felt while operating the vehicle with an engine speed
of 1500-3500rpm.
NOTE: Reprogram the ECM ONLY after confirming any of the scenarios as described above are
present.
SERVICE PROCEDURE / INFORMATION:
REMINDER: Customer satisfaction and retention starts with performing quality repairs.
• Reprogram the ECM following the normal FlashWrite procedure.
• See the information below for pak file applicability.
Subaru of America, Inc. (SOA) highly recommends connecting 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 (Flooded, EFB, 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 SDI 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 SDI 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 14V 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.

Bulletin Number: 09-90-22; Date: 05/20/22
Page 2 of 8
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.
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
GR8- 1100 and their Power Supply Mode feature have been tested and approved by SOA.

WARRANTY / CLAIM INFORMATION:
For vehicles within the Basic New Car Limited Warranty period, this repair may be submitted using
the following claim information:
Labor Description
Labor Operation #
Fail Code
Labor Time
MFI OBDII ECM Reprogramming
A455-288
UPG-48
0.4
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
newly- installed 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 Miscellaneous Detail field during claim submission.
NOTE: The pak file listings provided in this bulletin are the latest available at the time of publishing. Updates are often released thereafter without revision to the original bulletin. For this reason,
it is critical to always have the latest version of Select Monitor software installed on your system.
You can confirm if a later version is available by entering the CID listed in this bulletin into FlashWrite.
If a newer CID is shown as available in FlashWrite, reprogram using that file.
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.
