IMPORTANT: There are two distinct Service Procedures outlined in this bulletin. Be sure to
follow the one applicable to the vehicle being worked on.
• The first procedure applies (ONLY) to “In-Stock / Undelivered” vehicles.
• The second applies (ONLY) to vehicles already “Delivered” to customers (vehicle left the
retailer and later returned for this campaign).
• Follow the procedure applicable based upon the vehicle status as In-Stock / Undelivered
or Delivered.
Procedure for “In-Stock / Undelivered” Vehicles:
Adjust the CVTFII level following the procedure outlined in the applicable Service Manual and
outlined below for reference.
•
•
•
•
•
•
Connect the SDS Notebook and DST-I to the vehicle. Select SSM4 from the GUI.
When SSM4 opens, select Diagnosis.
After the vehicle specification populates, click OK.
Select Each System followed by Transmission and click Next.
Select Data Monitor and when all PIDs are displayed, click OK.
Select the data for “ATF TEMP”
CAUTION:
• CVTFII level changes along with CVTFII temperature. When inspecting CVTFII level,
observe the specified CVTFII temperature.
• Always use the specified CVTFII. Using other fluid will cause malfunction.
• Pay special attention to the following operations as the engine is at idle.
1. Idle the engine to raise CVTFII temperature to 35 — 45°C (95 — 113°F) on the Subaru Select
Monitor.
2. Operate the select lever in P → R → N → D and D → N → R → P to circulate CVTFII with the
engine idling.
3. Lift up the vehicle while the engine is running.
4. Remove the under cover front - transmission.

6.
When there is no CVTFII leakage, add the specified fluid up to the filler plug hole lower section.
A small amount of CVTFII may drain initially from the filler plug hole due to the presence of
residual fluid in the access port. It is expected 700 ml of fluid will need to be added to achieve
correct fill in all cases. If the CVT appears to need significantly more or less than 700ml, confirm
the fluid temperature is still correct for inspection and that the engine is running.
Specified Fluid: CVTFII by the quart (Part# SOA427V1660 – 12 quart case) or 5 Gallon
pail (SOA427V1670)
CAUTION:
If CVTFII is added up to the lower section of filler plug hole while the
transmission is in cold condition, overfilling of CVTFII occurs, causing the oil to spill out.

is necessary to measure the engine stall speeds in “R” and “D” range.
Purposes of the stall test:
• Operational check of forward clutch and reverse brake
• Operational check of the torque converter assembly
• Engine performance check.
1. Place wheel chocks at the front and rear of all wheels and engage the parking brake.
2. Turn the A/C OFF.
3. Using the Subaru Select Monitor, check if the throttle valve operates when you depress the
accelerator pedal.
•
Connect the SDS Notebook and DST-I to the vehicle. Select SSM4 from the GUI.
•
When SSM4, opens select Diagnosis.
•
After the vehicle specification populates, click OK.
•
Select Each System followed by Engine and click Next.
•
Select the data for Throttle Opening Angle and Accel. Opening Angle then click OK.
•
Confirm the throttle valve operation by viewing the data while manipulating the
accelerator pedal.
4. Check the engine oil level.
•
Park the vehicle on a level surface
•
After the engine has been off for at least 5 minutes, remove the engine oil level dipstick,
wipe clean and reinsert.
•
Remove the dipstick again and inspect. Confirm the engine oil level is between the
upper and lower marks on the dipstick before proceeding.

Check the engine coolant level. When adding coolant, always use SUBARU Super Coolant.
•
Park the vehicle on a level surface.
•
Check the engine coolant amount and if the coolant level is low, check for the coolant
leakage, then add if required to bring the level to full.
•
Make sure the coolant level in the reservoir tank is between “FULL” and “LOW”
with the engine in a cold condition.
•
CAUTION: Coolant may be HOT. Do NOT perform the following if coolant is hot.
Open the radiator cap and make sure that the radiator is filled with engine coolant up
to the filler neck.
Adjust the CVTFII level.
CAUTION:
• CVTFII level changes along with CVTFII temperature. When inspecting CVTFII level,
observe the specified CVTFII temperature.
• Always use specified CVTFII. Using other fluid will cause malfunction.
• Pay special attention to the following operations as the engine is at idle.
Idle the engine to raise CVTFII temperature to 35 — 45°C (95 — 113°F) on Subaru Select
Monitor.
Operate the select lever in P → R → N → D and D → N → R → P to circulate CVTFII with the

When the engine speed stabilizes, quickly record the engine speed and release accelerator
pedal. Shift the select lever to “N” range. Let the engine idle for at least one minute or more
allowing it to cool down.
Shift to “R” range and perform the same test again.
NOTE:
• Do not perform a stall test for over 5 seconds at a time. (From closed throttle, fully
open throttle to stall speed reading.) Failure to follow this instruction will cause the
engine oil and CVTFII to deteriorate and the clutch and brake to be adversely affected.
• Always cool down the engine for at least one minute after each stall test with the
select lever set in the “P” or “N” range and with the idle speed of 1,200 rpm or less.
• If the stall speed is higher than the specified range, attempt to finish the stall test in
as short a time as possible, to prevent the CVT from sustaining damage.
