NUMBER: WRH-20R
Rear Visibility FMVSS 111 Non-Compliance
DATE: 12/11/20
REVISED: 01/21/21
NHTSA ID: 20V-766
INTRODUCTION:
Subaru of America, Inc. (Subaru) is recalling certain 2020 model year Legacy and Outback vehicles
in which a firmware-over-the-air (FOTA) update to the Cockpit Control Module (CCM) software may
have timed out during the update.
A timeout failure during the data writing sequence could cause the data to become corrupted,
and if corrupted, may result in the Center Information Display (CID) going blank. The failure to
display the rearview image in the timing specified and/or periodic loss of rearview image creates a
noncompliance with the requirements of FMVSS 111 – Rear Visibility, increasing the risk of a crash.

Not all vehicles listed below are included in this recall. Coverage for all affected vehicles must be
confirmed by using the Vehicle Coverage Inquiry function on subarunet.com. This information is
now available.
The number of U.S. vehicles affected by this recall is 7,741.

MATERIALS REQUIRED:
An empty, USB 2.0 or 3.0 storage device (flash drive) will be needed to perform the update
procedure. The device should be dedicated to storing and transferring these updating files only. It
must be a minimum of 16GB or more in size and contain a NTFS file format before downloading the
update files onto it. Be sure to locate and re-format any existing USB drives used for updating Denso
CP1 audio units to remove any outdated update versions. They must be fully cleared and properly
formatted before adding these new update files to them.
IMPORTANT NOTES:
• NEVER change the update file names after downloading them.
• NEVER save any other files on the same flash drive.
There are various types of USB flash drive available from many suppliers. If the head unit does NOT
recognize the USB drive during the reprogramming process due to Controller IC type of USB drive
or compatibility with the Cockpit Control Module (CCM), confirm the flash drive format is NTFS.
The flash drive must be formatted for NTFS. If a recognition problem persists, use a different USB
flash drive from another manufacturer.
RECOMMENDED USB FLASH DRIVES:
•
Kingston®:
DataTraveler G3 Series, DataTraveler 100 G3 DT100G3, DataTraveler SE9 Series,
DataTraveler SE9 G2 3.0 DTSE9G2 and Digital Data Traveler 3.0 USB Flash Drive - Violet DTIG4
•
SanDisk®:
Ultra Series SDCZ48-064G-J57, Cruzer Blade Series and Cruzer Glide Series CZ60 SDCZ60064G-B35

IMPORTANT NOTE: There are 4 (FOUR) FILES required to complete this update for 2020MY
Legacy and Outback. ALL 4 update files MUST BE DOWNLOADED TOGETHER to the USB
Flash Drive before starting the update. PERFORMING THIS UPDATE USING A USB FLASH
DRIVE WITH ANY OF THE REQUIRED UPDATE FILES MISSING WILL LEAD TO A NONRECOVERABLE FAILURE OF THE COCKPIT CONTROL MODULE (CCM) REQUIRING CCM
REPLACEMENT.

STEP 1: Perform a Vehicle Inquiry on Subarunet to confirm WRH-20 applicability. If there is an
OPEN WRH-20 recall, proceed to STEP 2, otherwise this bulletin does not apply.
STEP 2: Turn the ignition ON and start the engine. Observe the Center Information Display
(CID) screen. If the vehicle presents with a black / non-responsive display or one that appears to
be continually rebooting, order a replacement Cockpit Control Module (CCM) following the normal
exchange unit procedure (NOTE: ONLY the CCM is required. Do NOT order a CID for this repair).
See STEP 2a BEFORE installing the exchange CCM to confirm the replacement part has been
updated with the latest (Version 4.0) software. If CCM replacement is not required, proceed to
STEP 3 below to continue with the reprogramming procedure.
STEP 2a: When receiving the exchange CCM,
inspect the back of the module for a GREEN dot
as shown here. This GREEN dot signifies the
module has already been updated with the latest
Version 4.0 software. NOTE: All related CCMs
shipped to retailers after 12/3/2020 have this
dot. The GREEN dot will be applied to related
exchange modules for six months. After that time,
the dot will be discontinued but the modules will
be OK for use. Proceed with CCM R&R following
the procedure in the applicable Service Manual.
VERY IMPORTANT:
•
Always record the serial number of the exchange CCM being installed on the Repair Order (RO).
•
Confirm and record the software version number installed in the exchange CCM on the RO. See
STEP 3 for instructions.
•
After CCM replacement, ALWAYS confirm proper back-up camera operation before releasing the
vehicle.
When complete, proceed to the Claim Reimbursement and Entry Procedures section and process a
claim for CCM replacement.

updates and an enhancement addressed by this reprogramming are outlined below:
•
Clarification of the post-FOTA procedure instructions
required to complete the update. The screenshot below
will appear and explain what must be done to complete
the update installation.
Software Update Installation Complete
To complete the update, your vehicle and STARLINK system must
be fully shut down. Please turn off the engine and exit the vehicle.
Lock doors, and let the vehicle sit for at least 5 minutes. It is recommended to walk at least 10 feet from the vehicle to prevent key
fob interference. After waiting at least 5 minutes, enter the vehicle
and turn the engine on. An “Update Successful” message will appear after a few moments. The update will then be complete.
•
Currently, the microphone level indication is incorrect. The indicator level has been corrected.
More microphone level indication information is included in TSB 15-275-20.
•
A reduced (low) volume (-6db) concern during handsfree conversation when using CarPlay has
been addressed to make the volume level consistent.
•
Voice recognition (VR) has been enhanced to improve recognition of short words (e.g. YES).
•
The program has been corrected to prevent repeated rebooting and system freeze-up immediately
after activation of AndroidAuto.
OPERATIONAL ENHANCEMENT INCLUDED:
The Auto Stop-Start On/Off function button has been moved from the bottom to top layer of the
system for easier use. A screenshot of how the button will appear is shown below.

If the vehicle is a 2020MY Legacy or Outback and the software version number (xxx-xxx) is
020-501, 020-502, 021-503 or 022-504, proceed to STEP 4 below. If the software version is
042-380 or higher, STOP as the module already has the latest software version installed. Proceed to
the WARRANTY / CLAIM INFORMATION section of the TSB and process a Version Check Only
claim. NOTE: The version identified MUST be entered in the Miscellaneous Detail field during
