Subject: VDC System Filter Clogged
Noncompliance with FMVSS No. 126, “Electronic Stability Control Systems”
The brake fluid used during the production of the potentially affected vehicles may have contained excess moisture. Excess moisture in brake fluid may cause a gelatinous material to form in the brake system. This material may accumulate and temporarily clog stability control-related valve filter(s) in the Vehicle Dynamics Control (VDC) system. In this situation, VDC performance may not fully comply with the FMVSS No.126 requirement. However, the brakes will continue to operate normally
If a stability control-related valve filter becomes temporarily clogged as described above, the system might exhibit reduced yaw rate control. In certain situations, when the VDC system is activated, it may not be as effective in preventing loss of vehicle control, which may increase the risk of a crash.
Retailers will perform an ABS sequence control (activation), then flush and replace the brake fluid in all potentially affected vehicles.
Not all vehicles in the VIN ranges listed below are affected by this campaign. Coverage for all affected vehicles must be confirmed by using the Vehicle Coverage Inquiry function on subarunet.com. This data will be available in the system before owner notification begins.
|Model Year||Models||Potentially Affected VIN Range (last 8 digits)|
|2015||Legacy||From F3076001 to F3076277|
|2015||Outback||From F3363225 to F3363905|

Subaru Service Bulletins are intended for use by professional technicians ONLY.They The international standard for excellence are written to inform those technicians of conditions that may occur in some vehicles, or in Environmental Management Systems. to provide information that could assist in the proper servicing of the vehicle. Properly Please recycle or dispose of automotive trained technicians have the equipment, tools, safety instructions, and know-how to products in a manner that is friendly to our do the job correctly and safely.

Subaru will notify all potentially affected vehicle owners by first class mail. This is expected to occur in May. Retailers will be advised when owner notification begins. A copy of the Owner Notification Letter is included at the end of this bulletin.
Each Subaru retailer will receive an affected VIN list from their Zone Office when owner notification begins. Vehicles will be assigned to retailers in the affected VIN list as follows:
Important: Retailer affected VIN lists include owner name and address information for ve- hicles affected by this recall. This information will enable retailers to follow up with owners of potentially affected vehicles. The lists contain owners’ names and addresses 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 purpose of completion of this recall.
RETAILER PROGRAM RESPONSIBILITY
Any vehicles listed in a recall/campaign that are in retailer stock must be:
Retailers are to promptly perform the applicable service procedures to correct all affected vehicles in their inventory (used, demo & SSLP). Additionally, whenever a vehicle subject to this recall is taken into retailer inventory, or in for service, necessary steps should be taken to ensure the recall correction has been made before selling or releasing the vehicle.
This repair requires brake fluid, which is available through the “Genuine Subaru Automotive Chemicals” program. No other parts are required for this repair.
For parts ordering purposes, retailers should use the part number listed below. Each case contains 24 bottles.
|Part Number||Description||Case/ Order Quantity|
|SOA868V9220||Brake Fluid – one 12-ounce bottle||24|
For claim reimbursement purposes, retailers should use the part number listed below which represents one 12-ounce bottle. Up to three 12 ounce bottles can be claimed for this repair.
|Part Number||Description||Claim quantity|
|SOA635004||Claim reimbursement for brake fluid– per 12 ounce bottle||Maximum 3|
will consist of 4 basic steps:
Step 1: Perform the Sequence Control
Step 2: Flush and bleed the brake system
Step 3: Perform the Sequence Control
Step 4: Perform a final bleeding of the brake system
Never let brake fluid come into contact with the painted surface of the vehicle body. If a spill occurs, wash away with water immediately and wipe dry.
Step 1: Perform the Sequence Control
If any ABS / VDC DTC(s) are stored, the sequence control function will not operate.
You can do it with Subaru Select Monitor SSM 3 or SSM 4.
Attach both instructions
Done with Subaru SSM 3:
select All other models – Each System Check – Brake Control System – ABS/VDC System
Done with SSM 4 (VXDIAG Subaru Scanner don’t support SSM4):
Select ABS Sequence Control Mode in the Work Support item list
The following screens will display in order:
Press the brake pedal firmly to the value established (approximately 100 bar), press OK and the Sequence Control will start. Keep the brake pedal depressed until the check is complete. Releasing the brake pedal before the Sequence Control is finished will result in an incorrect check
Note: there are lots of Subaru diagnostic tools in the markets.
For ABS Sequence Control, you can choose original Subaru SSM 3 scanner or cheap VXDIAG Subaru diagnostic tool. Both are confirmed to work good with Subaru diagnosis and programming.

Step 2: Flush then bleed the brake system
NOTE: There are several methods of bleeding the brakes including manual bleeding, vacuum bleeding, and pressure bleeding. Each method has its own advantages and disadvantages. To support these methods, a wide variety of brake bleeding equipment exists in the automotive industry. If a specialty tool is to be utilized, always consult the manufacturer’s specifica- tions and guidelines before attempting to bleed the brakes. Currently, the Service Manual supports the manual bleeding method.
VERY IMPORTANT: Always keep the Master Cylinder reservoir filled with brake fluid at the MIN level marked on the reservoir or higher to prevent entry of air.
VERY IMPORTANT: Flush and bleed the brake system (calipers) in the following sequence: RF → LF → LR → RR. Failure to perform bleeding in this sequence can result in air remaining trapped in the system resulting in a low or “soft” brake pedal.
the brake pedal slowly over the full range of travel until no air bubbles and fresh brake fluid is seen in the transparent vinyl tube. Tighten the caliper bleed screw and add fluid to the reservoir as it is depleted. Never let the fluid level fall below the minimum level (MIN) marked on the reservoir.
NOTE: Air bubbles should be removed after repeating the depressing operation approximately 15 times or more for the front calipers, and 20 times or more for the rear calipers.
Step 3: Perform the Sequence Control (Step 1) again
Step 4: Bleed the system a final time (5 – 8 above) to complete the procedure.
