SUBJECT:

P0890 TCM Power Relay Sense Circuit
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.
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.
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.
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.

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.
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 GR81100 and their Power Supply Mode feature have been tested and approved by SOA.
