ECM Reprogramming for DTC C1424
REVISED: 12/13/19
DATE: 12/10/19
INTRODUCTION:
In the interest of customer satisfaction, Subaru of America, Inc. (Subaru) is initiating a Service
Program to reprogram the Engine Control Module (ECM) on certain 2019-2020MY Ascent and
2020MY Legacy & Outback vehicles. In some vehicles, the current software may cause the sub
learning value control to operate improperly during the wake-up mode of the ECM. This could cause
repeated erroneous learning of the accelerator position which can result in the disabling of the VDC
function. When the VDC function is disabled, EyeSight, Reverse Automatic Braking (RAB), and
Electronic Parking Brake (EPB) auto release functions are disabled by the VDC fail signal causing
the VDC, EyeSight, RAB and EPB warning lamps to illuminate. This program affects approximately
115,729 vehicles.

Coverage for all affected vehicles must be confirmed by using the Vehicle Coverage Inquiry function
on Subarunet.com. This information is now available.
DESCRIPTION OF THE REPAIR:
Subaru retailers will reprogram the ECM.
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

RETAILER RESPONSIBILITY:
Retailers are to promptly perform this repair on any affected vehicles that may be in their inventory.
Additionally, whenever a vehicle subject to this Service Program is taken into inventory or in for
service, necessary steps should be taken to ensure the repair has been made before selling or releasing
the vehicle.
Any vehicles listed in a Service Program that are in the retailer’s stock must be:
•
Immediately identified
•
Tagged or otherwise marked to prevent their delivery or use prior to inspection and/or repair
•
Updated in accordance with the repair procedures outlined in this Service Program Bulletin.
OWNER NOTIFICATION:
Subaru is in the process of acquiring registration data and expects to notify affected vehicle owners
by first class mail beginning January 2020. Retailers will be advised when owner notification occurs.
RETAILER AFFECTED VIN LISTS:
Each Subaru retailer will receive an affected VIN list from their Zone Office. Vehicles will be
assigned to retailers as follows:
•
Original vehicle owners are assigned to the original selling retailer when their current address
is within a 100-mile radius of that retailer.
•
If the original selling retailer is inactive, the VIN has been assigned to the nearest active
retailer.
•
For any new owners or when original owners live more than 100 miles from the original
selling retailer, the VIN has been assigned to the nearest active retailer.
IMPORTANT: Retailer affected VIN lists include information for vehicles affected by this Service
Program. This information will enable retailers to follow up with owners of affected vehicles. The
lists contain owners’ names and phone numbers obtained from State Motor Vehicle Registration
Records. The use of such motor vehicle registration data for any other purpose is unlawful.
Accordingly, retailers are required to limit the use of these lists for the sole purpose of completing
this Service Program.

SERVICE PROCEDURE:
REMINDER: Customer satisfaction and retention starts with performing quality repairs.
•
Reprogram the ECM following the normal FlashWrite procedure.
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.
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.
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.

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.
CALIFORNIA “VEHICLE EMISSION RECALL - PROOF OF CORRECTION”
CERTIFICATE
The California Air Resources Board and the Department of Motor Vehicles Registration/Recall
Program requires that all emission related Recall/Campaign or Service Program repairs be completed

California a completed “Vehicle Emission Recall - Proof of Correction” certificate. Vehicle owners
should be advised to retain this certificate because the California Department of Motor Vehicles may
require they provide proof this service program repair has been completed.
