01 QMR OF THE MONTH
We are pleased to announce this month’s Winner of QMR of the Month:
Tau Jeppesen from
Young Subaru in Ogden, UT.
This month’s winning QMR involved a 2019 Outback 3.6R which
presented with a crank / no-start condition. After Tau confirmed
the reported condition, a failed fuel pressure test aimed him at the
fuel pump and related wiring as his first points of inspection. Tau
supplied an auxiliary power source to the fuel pump and the engine
started normally. He then proceeded with power supply checks while
working his way forward from the fuel pump to the fuel pump relay.
Further inspection revealed there was no ground signal coming from
the ECM to activate and close the fuel pump relay. Because his SSM
data for the ECM showed the pump was being commanded ON,
Tau felt there was a problem within the ECM which unfortunately,
was not the case. After replacement, the no-start condition persisted
although, the fuel pump relay was now operating normally. Next,
Tau removed the trunk trim panel to access the fuel pump controller
and proceeded with more voltage checks at the harness connection.
His checks revealed less than 1 volt was present on the controller’s
power supply wire. Using his DVOM and the split-half technique, Tau
isolated the root cause of the low voltage issue as a poor contact at
Pin 12 of harness connector B60. Repairing the poor connection
restored proper voltage to the fuel pump controller and normal engine
starting. Tau’s excellent QMR was accompanied by a selection of
detailed photos and test results to supplement his report.
In appreciation for going the extra mile and sharing his experience
with us, Tau will be receiving the following:
A $500.00 Snap-On gift card.

This series features TechTIPS articles frequently referred to by Techline. This month’s feature from
September 2015 helps Technicians understand which DTC to diagnose when multiple are present.
01 UNDERSTANDING DTCS AND HOW TO PROCEED PROPERLY WITH REPAIRS
The Techline has been receiving calls from Technicians who in some cases are following the wrong
trouble tree when diagnosing DTCs. When a vehicle comes in with multiple codes stored, you
should always look at the Freeze-Frame (FF) data and the Time Count PID first. This will be the best
place to get a direction as to what the first DTC to set in the affected system was. Never clear any
DTCs until all have been recorded and the corresponding FF data saved electronically.
In the example below, a customer could come in with a traction (VDC) light, Check Engine light and
A/T Temp light on. If the root cause issue is not current, they could come in with no warning lights
on at all. The Technician connects the SSM and the following DTCs are stored:
• VDC code C1424 (ECM failure): DTC indicates there is a code in the ECM.
• ECM code P0700 (AT request MIL on): DTC indicates there is a code in the TCM.
• TCM code P0841 (Secondary Pressure Sensor malfunction): This DTC is the root-cause
issue and should be the code the Technician diagnoses first.
In this case, the other codes (C1424 and P0700) are secondary codes. The TCM informed the other
control modules of its failure by setting the P0841. Whenever a control module has an issue and
stores a DTC, there is a strong possibility of DTCs in other modules due to the interdependence of
one system on another through operation of the high-speed CAN system.
You may also see CAN communication codes stored. These DTCs should be interpreted as
secondary or by-product codes unless no other codes are stored. Always check each system for
DTCs as once the issue has subsided, the only place you will see the DTC is in the affected system.
An All-System scan will only provide current codes which in the example above, would be the C1424.

01 CPO PROCEDURE FOR TURBOCHARGED SUBARU VEHICLES
Due to the high number of phone
calls presented to the Techline, we
felt it necessary to remind retailers
of the correct CPO procedures for
Turbocharged Subaru vehicles.
Checking the CID/CVN over the phone
for CPO purposes is NOT the correct
procedure. The information below
was published in the September 2015
TechTIPS Newsletter:
Please ensure all criteria are met
before sending in a CPO CID/CVN
Certification request to avoid delays.
Once the vehicle has passed this part of the inspection process, you should proceed with the rest of the
decision-making process on certifying the vehicle.
As the CPO 152-point inspection form indicates, if a vehicle has ANY performance modifications, it cannot
be enrolled as a Subaru Certified Pre-Owned vehicle. If there are any other non-performance related
modifications, the vehicle must be returned to stock, with all stock/OEM parts installed before it can be
enrolled as Certified. Non-compliance to these requirements may result in chargeback to the retailer for
replacements after it is sold as a Subaru CPO unit.
02 H6 CYLINDER HEAD REPLACEMENT PRECAUTION
Techline has received reports from the field concerning
AVCS related DTCs after H6 cylinder head replacement.
When replacing H6 cylinder heads, thoroughly inspect
both the new and old cylinder heads to ensure all parts
not included with the new cylinder head have been
transferred. The image to the right shows one of the oil
galley plugs that must be transferred from the old cylinder
head.

07 IDENTICAL ELECTRICAL CONNECTORS
Most electrical connectors in Subaru vehicles have unique designs that allow them to be plugged in to
only one component. However, this does not apply to all connectors. Some connectors have the same
physical shape and will connect to multiple components. These connectors don’t always have the same
power, ground, or signal pins. If the component receives the incorrect circuit path, the component could
be damaged. This is very common when installing Keyless Access Control Modules. Below are some
examples of identical connectors for different components.
07 2019 FORESTER DOOR MIRROR REVERSE TILT-DOWN FEATURE
When backing up the vehicle, the front passenger’s side outside mirror will turn downward automatically
to provide better rear visibility. The outside mirror glass will return to its original position approximately 9
seconds after shifting out of reverse or when the ignition is turned off. This feature is turned on and off via
the combination meter setting screen. By default, only the passenger mirror will tilt down. If requested by
a customer, the driver mirror can also be enabled to tilt down in reverse. This setting can be accessed by
using SSM and changing the appropriate power seat memory setting. Instructions to enable this are found
in the Service Manual under: POWER SEAT MEMORY(DIAGNOSTICS) > Customize.

16 VIBRATION AFTER TRANSMISSION OR ENGINE REMOVAL
Techline has received increasing concerns of vibration after transmission or engine removal. Multiple
cases have been identified where the vibration has been traced back to the snout of the torque converter
being broken. This can happen if the torque converter holder tool is not used. When removing an engine or
transmission the component needs to be released as straight as possible without any rocking or pitching.
The photo above shows the nose of the torque converter is broken off and remaining in the crankshaft.
Also note, there is no torque converter holder tool installed to the transmission.

During component removal it is imperative to follow all steps of the procedure as outlined in the Service
Manual. In addition, always confirm both dowel pins are installed in the engine block before engine reinstallation
to insure proper engine to transmission alignment.
