01 QMR OF THE MONTH
We are pleased to announce this month’s winner of the QMR of
the Month.
Shaun submitted a very detailed QMR reviewing his diagnosis of a
2013 Outback with an unusual parasitic draw. Shaun successfully
split-halfed the system and was able to determine the source of
the draw was from the driver’s power seat memory control module
staying awake, but he didn’t stop there. Further testing led to
him finding a short to ground on the seat frame that simulated
the signals from the setting buttons which prevented the module
from entering its sleep mode. This resulted in a wiring repair
for the seat harness. This kind of detailed insight to the thought
processes applied during the diagnosis was very helpful to us
from several perspectives. In this case, it resulted in reviews of
the service information supplied, technical training, and of course
quality improvements based upon finding the root cause of the
condition. This demonstrates once again that individual reports
can have significant impact so, keep them coming!
In appreciation for going the extra mile and sharing his experience
with us, Shaun will be receiving the following from his FSE:
Any Subaru Service Technician can participate in QMR of the
Month. See the February 2013 Tech Tips for full details. You
may see your name here in a future Tech Tips.

New Techline Pre-Call Worksheets have been created and posted on Subarunet.com/Service/Pre-
Call Worksheets. These worksheets have been structured to provide technicians with an organized
format to record results of basic system diagnostic checks and other relevant information during an
investigation to help identify a root cause for concern. Use of these new forms is strongly encouraged
and may ultimately expose specific areas of investigation that might otherwise be overlooked.
In the event additional technical assistance is needed, complete a “Dealer Request for Technical
Assistance” form and submit it along with the specific system worksheet. Contact Techline and have
a case created. Inform the representative that you have completed the worksheets and would like to
send them in for review. Once received, they can be used to analyze your complete and accurate
results to better provide you with the best possible next step recommendation. This information can
also be accessed by field staff through an existing Techline case for further assistance when needed.
**In order to effectively manage incoming correspondence, worksheets should not be
forwarded to the Techline without an accompanying case number**
01 NEW TECHLINE PRE-CALL WORKSHEETS
Starting with 2010 Legacy and Outback CVT and continuing with each subsequent new model
release (2012 Impreza 2.0, 2014 Forester, etc…), FHI incorporated logic into the TCM for it to consider
the driver’s request for heat as a factor in determining where to set the CVT turbine speed. The
HVAC head unit supplies information through the CAN on the driver’s request for heat based upon
a combination of blower fan operation and temperature (blend door) settings. The TCM logic then
translates these into a High heat request, a Low heat request, or No heat request. Depending upon
the level of the request, the TCM then instructs the CVT to change the drive ratio to create a net
increase in turbine speed (engine rpm) so that additional heat is supplied to the passenger cabin. As
a result you may hear comments or concerns from customers during periods of cold weather. This is
particularly true during extreme or long lasting cold weather events. These may include comments
ranging from customers noting that the engine rpms seems to be staying higher, to the CVT not
entering its regular final drive ratio, to a concern that the CVT is hesitating (again not advancing to
its regular final drive ratio). In each of these cases a detailed interview and review of the customer
concern found that the symptom the customer observed was that the engine rpms were higher than
the customer had seen previously (during warmer weather). The reason in each case was simply
cold weather prompting an increased demand for cabin heat by the driver which resulted in the engine
rpms being kept high to provide that heat. This was easily verified during similar cold conditions by
turning the blower fan to the OFF position for several seconds while cruising at a steady speed in a
fully warmed car and watching the resultant drop in rpms. If a customer reports a concern with higher
rpm operation as a result of this logic and wants to reverse that effect, recommend that they reduce
the temperature setting (or turn the blower fan to OFF) until it has the desired effect on engine rpm.
Either of these actions will reduce or eliminate the input to the TCM that results the rpm increase.
Otherwise simply explain that this is characteristic operation of the engine and transmission during
cold weather resulting from the vehicle trying to meeting the driver’s request for more heat based upon
the HVAC temperature and blower settings.

parties involved. In an effort for us to assist you, please keep these points in mind when you contact
the Techline:
• Always get the name of the Techline Representative that you speak with.
• Get a Case Number.
• Follow-Up with the Techline Representative about your findings.
To close a case when the issue is resolved, we ask that you contact the Techline or use option #8 “To
Close a case” on the phone system during our business hours to advise us of the repair that fixed the

Should you receive a customer complaint
of the power rear tailgate not working
properly and you have checked the system
for Diagnostic Trouble Codes and found
a DTC B250F (Rotation Sensor Failure),
make sure the rear gate stays are not
bent at the attachment bracket as shown
in this photo to the right. If this condition
is confirmed, the gate stay will need to be
replaced. Do not attempt to repair the bent
bracket.

The SOA Techline and Quality Assurance
sections of the Service Department have
recently had inquiries regarding cylinder wall
discoloration noticed during installation of the
updated piston rings.
In some cases, the Technician also reports
measurements are out of specification
when measuring the cylinder bore. It is
required per the Service Manual that the
cylinder bore must be checked at 68 degrees
Fahrenheit, otherwise some variations are
normal. The photo to the right is an example
of this discoloration. It is in no way harmful to
install the updated piston rings and use the
existing block.
All of the Oil Control Ring TSBs have been
recently updated on STIS with additional
helpful information based upon field feedback, please make sure to review all of the enhancements.
We frequently encourage all technicians to download the very latest Service Bulletin from STIS before
performing it to ensure they have the latest information available.
02 DISCOLORATION OF CYLINDER WALLS
As mentioned in the February TIPS, the importance of taking quality pictures is essential when
submitting an Authorization Request (AR) for consideration. Subarunet allows for each picture to be up
to 5MB which is possible only when using a quality camera. Certain cell phones have the capability of
providing quality pictures however, they must be saved in the proper format, Actual Size.
Prior to the customer leaving your dealership, take a minute to review the pictures you are about to
submit to ensure their quality.
A camera is the best tool to use when taking pictures to attach to an AR. However, if you are sending
pictures taken by a cell phone, it is recommended to choose the Actual Size when prompted. This
will provide the best quality photo possible. The quality of the Small (KB), Medium (KB) or Large (KB)
size pictures in most cases have poor resolution. This makes it necessary for us to request additional
pictures.
Always review your pictures prior to attaching them to your AR request.
