NOTE: See Appendix A for additional information regarding control module reprogramming.
STEP 1-B: Display the following data using the Subaru Select Monitor (SSM4).
•

Switch the ignition switch to the OFF position, wait 30 seconds then switch back to the ON
position.

•

IMPORTANT: Restart the SSM application after the TEMPORARY PAK file is installed.

•

Verify the VIN information is correct and select “Diagnosis”.

•

Select “Target Each System.”

•

Select “Transmission” then select “Data Monitor”.

•

If required, click the “Delete All” button to move all items to the left side of the screen before
making the selection. Scroll through the select signal list and confirm the “Slip A Information,
Slip A Mileage 1, Slip A Mileage 2, and Slip A Mileage 3” items are selected (Blue
Highlighted). Once the items are highlighted, click the “Add” button.

IMPORTANT: In the case of failed control module communication with SSM after the installation
of the temporary PAK file, check and confirm the interface setting is matched to the equipment being
used (SDI, DSTI, & DST 010).
•

Confirm the selections are now transferred to the column on the right side. Continue by clicking
the “OK” button.

STEP 2A: Determining the CVT chain slip data.
•

If CVT chain slip has been detected, the “Slip A Information” will display a value higher than
zero and the mileage will be recorded in any of the three mileage monitor (Maximum, Minimum,
Average) items.

•

If CVT chain slip is NOT detected, there will be a zero in all four mileage monitor items.

Go to STEP 3

1

Review the vehicle repair history

Go to STEP 2B

STEP 2B: Check the vehicle repair history and confirm if the vehicle has had any previous CVT
replacements.
NOTE: For the best accuracy, always refer to the “out mileage” of the repair claim history.
Has the CVT assembly been previously replaced?
YES – Proceed to STEP 2C.
NO – Proceed to STEP 4.

STEP 2C: Compare the mileage of the latest CVT chain slip checked in STEP 2A with the mileage of
the previous CVT assembly replacement.
NOTE: The Slip A Mileage values shown within the data will ALWAYS be in miles
regardless of what unit is specified.

•

If the values of “Slip A Mileage 1, 2, and 3” are ALL greater than the mileage of the last CVT
replacement , proceed to STEP 4.

•

If the values of “Slip A Mileage 1, 2, and 3” are NOT ALL greater than the mileage of the last
CVT replacement, proceed to STEP 3.

STEP 3A: Disconnect the vehicle from the SSM. Remove the 10mm bolt retaining the insulator cover
on the right side of the CVT.

Bulletin Number: WRK-21_22R; Revised: 08/26/22

Page 10 of 32

STEP 3B: CAREFULLY lift the insulation only as far as necessary to expose the plug as shown
below.

STEP 3C: Install and align the specialty plug / holder (18361AA090) as shown below.
•

The holder is designed to provide the proper insertion angle for the videoscope camera.

•

Install the tool by tightening the holder down BY HAND ONLY.

•

Slightly loosen the holder so the flat section of the tool is facing downward (parallel to the floor).
See the example illustrations below.

NOTE: NEVER use any wrench, socket, etc. when
tightening the plug / holder tool. Teflon Tape can be
applied to the holder threads for added stability.

Bulletin Number: WRK-21_22R; Revised: 08/26/22

Page 11 of 32

STEP 3D: Perform a visual inspection of the chain guide rail.
•

Make sure the OTC videoscope's threaded camera tip is screwed on tight prior to usage. Prepare
the videoscope camera by measuring and marking approximately 5mm (0.2inch) from where
the metal section of the scope tip meets the flexible portion. This section can be marked using a
marker or tape. Use the example photos below as a guide.

•

Identify the top section of the scope camera lens while performing a function test of the
videoscope. This can help for the scope view positioning.

•

Insert the videoscope camera into the plug / holder up to the previously marked line

CRITICAL: To prevent any unwanted damage to the videoscope tip, ALWAYS use caution
when inserting and removing the videoscope camera into the holder.

•

Set the magnification of the videoscope to 1.0.

STEP 3F: Remove the holder (18361AA090).
•

Reinstall the original plug with a NEW gasket.
Tightening torque: 35 N·m (25.8ft-lbs.)

•

Install the bolt retaining the insulator cover.
Tightening torque: 8 N·m (5.9ft-lbs.)

STEP 3G: Using the inspection results from STEP 3E, see the table below to determine the next
course of action.

CORRECT POSITION

Proceed to STEP 5

INCORRECT POSITION 1 OR 2

Proceed to STEP 4A

STEP 4A: Replace the CVT assembly.
The service procedures for CVT assembly replacement remain unchanged. Always refer to the
applicable Service Manual and review the full requirements of the repair being performed. The
Service Manual procedures contain information critical to performing an effective repair the
first time, every time. This includes but is not limited to important SAFETY precautions, proper
inspection criteria, necessary special tools, required processes and related one-time-use parts needed
for a complete and lasting repair.
Refer to STIS: Transmission/Transaxle > CONTINUOUSLY VARIABLE TRANSMISSION >
Transmission Assembly > Removal/Installation
IMPORTANT NOTE: When replacing the CVT assembly, ALWAYS perform a transmission cooler
flush as per the Claims Policies and Procedures Manual using SOA868V9255.
STEP 4B: Proceed to STEP 5.
STEP 5: Reprogram the TCM with the applicable PAK file. When reprogramming is complete,
confirm there are no faults stored in the TCM.

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
before a vehicle registration is renewed. Please provide owners of vehicles registered in the state of
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. Additional certificates
are available through normal parts ordering channels using part number MSA6P1301. Quantity 1 = 1
booklet of 50 certificates.

SERVICE PROGRAM IDENTIFICATION LABEL:
Type or print the necessary information on a Campaign Identification Label. The completed label
should be attached to the vehicle’s upper radiator support. Additional labels are available through

Appendix A
PRECAUTIONS:
Confirm the PC being use for reprogramming is connected to a known good power source. Turn off
any screen saver settings. Make sure the PC is not in power saving mode and is set to the normal power
mode. Always inspect the DST-I/DST-010 and PC cables prior to programing. Confirm the cables are
CORRECT and there is no exposed wiring, corroded connections, or loose fitment. See the example images below.

STEP A-1: Subaru of America, Inc. (SOA) highly recommends connecting either the Subaru Midtronics DCA-8000 Dynamic Diagnostic Charging System or the Subaru Midtronics GR8-100 Diagnostic
Battery Charger to the vehicle and utilizing the Power Supply Mode feature to supply a stable 13.5 volts
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 (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
