INTRODUCTION:
This bulletin provides helpful information about operating conditions observed in the eld for Technicians to use
when diagnosing customer concerns which may arise while operating Harman Gen 3 Navigation and Display Audio
systems. We will continue to add to this bulletin as more information becomes available.
CONDITION# 0.1 Head Unit Lockup:
a. HMI (Human Machine Interface) locked up
b. Touch screen not taking input
c. Complete system locked up (no hard keys and no audio)
d. Only the STARLINK screen is shown
CAUSE:
1. Checking for audio in an internally amplied system will indicate, if the microprocessor is
communicating and processing audio. In Harman Kardon amplier equipped audio systems,
if audio is present, it means the Head Unit is sending CAN data to communicate with the
amplier. If you do not hear anything on a Harman Kardon amplier equipped system, no
absolute conclusions can be drawn as there can be multiple causes of no audio (e.g. no CAN
activity, faulty audio connections, faulty amplier, etc.).
2. If hard keys are working, this could indicate that the touch panel is having issues. The system
is up and running, but touch screen input is not being registered.
3. If hard keys are working, this helps determine the system is receiving input and responding
to that input (volume, source changes, preset advance, VR, etc.).
4. Another example of checking that the Operating System is responding. From past reports,
detecting a CD/USB was often reported as a freeze or lockup, but the rest of the system was
operating.
NOTE: Past reports of not receiving phone calls on the head unit were reported as a freeze or lockup
but found to have lost connection between phone and Head Unit.
Based on the data collected follow the service manual to complete diagnostic and isolate the concern
leading to a repair.

Bulletin Number: 15-221-18R; Revised 02/12/21 Page 3 of 45

RECOMMENDATION:
List of things to try:
1. Conrm if audio is working- Note if working from all speakers and if volume can be adjusted
2. Are the hard keys working?
3. Are the steering wheel controls working?
4. Is the USB detected? CD detected? -> is audio playing?
5. Does the phone show that it is still paired? Does the head unit show active pairing?
Based on the data collected follow the service manual to complete diagnostic and isolate the concern
leading to a repair.
CONDITION# 0.2 Blank/Black Display:
• Backlight o
• HMI showing black screen
• Broken volume knob
CAUSE:
1. If the HMI is still visible, this points to an issue with the display backlighting.
2. Backlit buttons indicate the HU is receiving power and certain components on the HU are
operating. Note: that ashing buttons may indicate the system is rebooting.
3. Audio output present and volume level adjustable indicates the microprocessor is running –
this could narrow the issue down to a service crash (HMI) or for example, a connection issue
(but not necessarily guarantee either of these are the cause).
4. If the screen is turned o via the volume button or Settings menu entry, hard keys will turn
the screen back on. If the user is experiencing this every ignition cycle without turning the
screen o themselves, this could be a problem with the volume knob being broken or stuck.
5. For vehicles not equipped with an external amplier, a beep sound when the screen is pressed
indicates the microprocessor is running and receiving input from the touch panel. Possibly a
backlighting issue. For vehicles equipped with a Harman Kardon amplier, if a beep is not
heard, this could indicate the amplier is not communicating or the system is not sending a
request to the amplier to play a beep. In this scenario, it is hard to draw a conclusion.
6. Conrm the Head Unit (HU) is communicating on CAN. If none of the HU CAN messages
are being seen, the HU could be stuck in an o state as it is not reacting to CAN wakeup.
RECOMMENDATION:
List of things to try:
1. Short or Open circuit: Current draw (use clamp meter on battery wire going into the radio).
Note the current draw to help determine what state the HU is in.
2. Shine ashlight on the screen and see if HMI is still there
3. Are the buttons backlit?

Bulletin Number: 15-221-18R; Revised 02/12/21 Page 4 of 45
Continued...
4. Do you hear audio? Can you change the volume? Can you change the audio source?
5. Does pressing hard keys awake the display screen?
6. When pressing the screen – do you hear a beep (conclusion can only be drawn when hearing
a beep)?
7. Check CAN for trouble.
Based on the data collected follow the service manual to complete diagnostic and isolate the concern
leading to a repair.
CONDITION# 0.3 HMI partially shown:
CAUSE:
1. Audio output means the services are working => the microprocessor is operating.
2. For vehicles not equipped with an external amp, a beep sound when the screen is pressed
indicates the microprocessor is running and receiving input from the touch panel. Possibly
a backlighting issue. For Harmon Kardon amplier vehicles, if a beep is not heard this
could mean the amplier is not communicating or, the system is not sending a request to the
amplier to play a beep. In this scenario, it is hard to draw a conclusion.
3. Certain buttons/labels are dependent on software conguration or CAN messages. Knowing
what is shown and what isn’t shown helps to diagnose the root cause.
4. Audio services are running, indicating the microprocessor is not locked up.
5. If the issue is addressed, this points to something causing the HMI to not update correctly,
helps narrow down the issue to possibly a timing issue or an issue with the HMI.
RECOMMENDATION:
List of things to try:
1. Do you hear audio? Can you change audio source?
2. When you press the screen – do you hear a beep (conclusion can only be drawn when hearing
a beep)?
3. Are button labels there - no/some/all labels?
4. Is metadata shown (album, name of song, …) on the display?
5. Can you change between screens using the hard keys?
a. When you go back to blank screen – still in that state?
Based on the data collected follow the service manual to complete diagnostic and isolate the concern
leading to a repair.

Bulletin Number: 15-221-18R; Revised 02/12/21 Page 5 of 45

CONDITION# 0.4 Audio Output:
• No audio could be heard
• No control of audio
• Poor audio quality
CAUSE:
1. When the head unit is congured for an external amplier but installed in a vehicle without
an external amplier results in no volume control. Head unit to be set for four speakers or six
speakers installed into a vehicle with an HK amplier will experience things like double (or
echo) beep sounds when the touch screen is pressed, NAVI prompts and music playing at the
same time.
2. Conrming speaker wiring and related connections.
3. Knowing the audio source which a concern helps with trying to recreate the issue and
determine if it is a signal strength issue (for tuner sources) or possibly an audio processing
issue. If the condition occurs on all sources, it could be audio processing or a problem with
speaker connections, the speakers, or the amplier.
4. Audio will either not output on certain channels if speaker outputs are open. Audio will
sound static or distorted when shorted.
5. Four speakers or six speaker Head Units will report DTCs for short or grounded connections
for each channel in case of the wrong conguration. External amplier will register DTCs
for HK amplier systems.
6. If the volume indicator is shown but volume level does not change, this could be because
the Head Unit is congured for external amplier, but no external amplier is connected. If
the volume indicator is not shown, it is possible certain audio services are not responding or
crashed.
RECOMMENDATION:
List of things to try:
1. Is the part number of HU for internal or for use with an external amplier?
2. Is there continuity on all the speaker outputs?
3. Does the issue occur on a specic source? Are any speaker outputs grounded/shorted?
4. Any DTCs for speakers (for externally amplied radios path between HU and amplier is
not checked)?
5. Is volume control functional?
6. Is static heard on all channels (only left/right, front/back)?
In case the audio output is not restored, please follow troubleshooting owchart using the link on
Subarunet (Service Operations & Technical/ Forms and Downloads) and capture the results in the
applicable questionnaire.

• Gen 3 Harman
Based on the data collected follow the service manual to complete diagnostic and isolate the
concern leading to a repair.
CONDITION# 0.5 iPhone is connected to the hub but CarPlay doesn’t launch/function:
CAUSE:
• Indication of the phone charging conrms the USB hub is connected to power.
• If CarPlay/Android auto button is colored, this indicates the system recognizes that a CarPlay
or Android Auto device is connected.
• When connected the CarPlay logo should appear. It means the phone is reacting to the
request to load CarPlay. Some devices will just change the top status bar color to blue.
• Sometimes cables that are not Apple certied are purchased from Amazon (cheaper cost) but
do not allow for data transfer speeds required for CarPlay.
• Hub is only powered on via ACC line.
• This helps narrow down the variables, if the phone isn’t working in multiple cars then this
points to an issue with the phone. If another phone does not work in customer’s vehicle, then
some of the other components should be looked at (hub, cables, HU).
• Device compatibility is important here, certain devices may be too old and no longer
supported, or newer devices may have some new software that is not yet supported.
• Always important to note the version the phone is running. There are cases where certain
versions of iOS may have had stability issues.
RECOMMENDATION:
List of things to try:
• Is phone charging? Conrm connection from hub to Head Unit.
• Carplay icon gray or in color?
• Does Carplay show up on the phone? Does it show blue bar on the top of the phone?
• Original cable used? Damages?
• Is ACC on?
• Does phone work in another vehicle? Does another phone work in this vehicle?
• Is the phone listed as a compatible device in the owner manual?
• What’s the IOS version?
Based on the data collected follow the service manual to complete diagnostic and isolate the concern
leading to a repair.

CONDITION# 0.6 Black display/No Rear View Camera image displayed when vehicle is in
reverse:
• System does not switch to rear camera view.
• Gridlines not shown on screen.
• Active, static or both types.
• Black screen shown.
• With or without gridlines?
CAUSE:
1. Seeing an indication on the dashboard the vehicle is in Reverse means CAN signal is being
sent on the CAN bus (where CAN is used).
2. Power on the reverse line going to the Head Unit when shifting to reverse.
3. Conrm the harness is fully connected between HU and camera. Check for loose/bent/
broken pins.
4. If the Head Unit works normally in another vehicle, this points to a possible issue with the
camera or the harness connections.
RECOMMENDATION:
List of things to try:
• Does the cluster indicate the vehicle is in reverse?
• Is there power on the reverse line going to the Head Unit when shifting to reverse? Measure
voltage on Pin 2 of the 28 pin harness then check if there is a non-zero voltage present on the
line when the vehicle is shifted to reverse.
• Is there CAN activity? Use the dealer menu to check for CAN presence or, use SSM tool to
check for any DTCs and HU part number.
• Dealer menu has a rear camera section which allows for gridlines to be enabled/disabled.
• Is the connection to the camera complete?
• If the HU is swapped into another vehicle, does the issue still occur?
Based on the data collected follow the service manual to complete diagnostic and isolate the concern
leading to a repair.

CONDITION# 0.7 Learning about three types of resets: Reboot, Restart and Factory Reset:
RECOMMENDATION/EXPLANATIONS:
This procedure represents the ordinary shutdown process of the Head Unit (HU) and explains how
the state of the HU changes due to actions and with time.
States:
Radio on: Is booting or is booted but display, audio and is not available (like a computer where
display is disabled)
Radio active: Radio is on + display is shown, entertainment features are available
CAN on/o: Vehicle bus is on and sending messages back and forth
Point of no return: At this point, you can‘t stop the shutdown process anymore > radio won‘t turn
back on until the shutdown is completed.
What would happen if ignition was turned on at certain points in the shutdown procedure?
1. Radio would stay on and active.
2. Radio would stay on and active.
3. Radio would stay on and get active.
4. HU would complete the shutdown procedure and start up again > it could take up to 15
seconds until the radio turns back on.
Critical point: If driver shifts into reverse during this period, the shutdown process would stop
(Reverse Camera delay) > if undo reverse the HU will continue the shutdown process and only show
the reverse camera screen > during this time frame no other features will be available!

Bulletin Number: 15-221-18R; Revised 02/12/21 Page 9 of 45
Continued...
CONDITION# 0.8 The shutdown process of the HU inuenced by an ACC delay:
RECOMMENDATION/EXPLANATIONS:
ACC delay:great
Occurs if ignition is turned o and door is not opened. It takes 3 minutes until the start of radio
shutdown.
What would happen if ignition was turned on at certain points in the shutdown procedure?
1. Radio would stay on and get active.
2. HU would complete the shutdown procedure then start up again > it could take up to 15
seconds until the radio turns back on.
Critical point: If driver goes to reverse during this period, the shutdown process would stop (Reverse
Camera delay) > if undo reverse the HU will continue the shutdown process and only show the
reverse camera screen > during this time frame no other features will be available!
CONDITION# 0.9 Shutdown process of the HU inuenced by a Smart Accessory delay:

Bulletin Number: 15-221-18R; Revised 02/12/21 Page 10 of 45
Continued...
RECOMMENDATIONS/EXPLANATIONS:
Smart Accessory delay:
The delay occurs when customer pairs a phone > starts a phone call then turns o the ignition o
during the call. As a result, the normal accessory delay time of 3 minutes changes to 10 minutes,
as long as the phone call is active and unless a door is opened. If a door is opened, the procedure
continues from action „Door open“ as shown in the diagram above.
What would happen if the ignition was turned on at certain points during the shutdown
procedure?
1. Radio would stay on and get active.
2. HU would complete the shutdown procedure and then start up again > it could take up to 15
seconds until the radio turns back on.
Critical point: If driver shifts into reverse during this period, the shutdown process will stop
(Reverse Camera delay) > if shifted back out of reverse, the HU will continue the shutdown process
and only show the reverse camera screen. During this time frame, no other features will be available.
CONDITION# 0.10: Restart vs. Factory Reset:
RECOMMENDATION:
1. Restart HU by holding the volume button and select button for 10 seconds. This forces a
“cold” boot > there is no ordinary shutdown procedure.
2. Factory reset: by clicking Factory Data Reset in Settings > Factory reset should be the last
thing to try. Only for use in serious cases as it clears the following settings/data:
• Radio presets
• Paired phones
• Phonebook data
• Driver Proles
• Synced media device data
• Navigation sensor calibration
• Parts of the settings go back to default

Bulletin Number: 15-221-18R; Revised 02/12/21 Page 11 of 45
Continued...
CONDITION# 0.11 When selecting the MySubaru Application on the head unit, a
Communication Error may occur that displays along with a specic code. In the example image
below, the error code is 101:
CAUSE: Communication Errors can occur for many dierent reasons. For example, the issue
causing the Communication Error could be that a Smartphone had not been paired to audio head unit.
RECOMMENDATIONS:
Before selecting the MySubaru application on the audio head unit, be sure to rst pair the customer’s
smartphone. Allow the smart phone to sync all contacts and allow notications if requested. This
procedure will allow the current date and time to sync with the audio head unit. It is also possible to
manually set the date and time by using the Vehicle Settings menu on the Multi-Function Display to
set the clock.
Information about Communication Error codes can be found in the Troubleshooting Section of the
2019 SUBARU STARLINK Safety and Security Owner’s Manual.

Bulletin Number: 15-221-18R; Revised 02/12/21 Page 12 of 45
Continued...
CONDITION# 0.12: Subject vehicle consistently displays multiple horizontal lines across the
display screen each time the backup camera feature is operated. NOTE: This condition applies
to 2017MY Impreza ONLY.
CAUSE: Investigation found the cause of this condition to be connector R98 not fully connected /
engaged.
RECOMENDATIONS: Access and disconnect R98 and examine closely for any bent or displaced
terminals. If OK, rmly reconnect and ensure a solid connection. Retest backup camera operation and
conrm a consistent, high-quality image is displayed.
Rear View Camera (RVC)/Back-up Camera1.0
CONDITION# 1.1 No backup camera after head unit replacement or battery disconnect (2016
Dec TechTIPS):
CAUSE: Whenever the Audio / Navigation head unit requires removal on a 2017 Impreza, it is
important the Service Manual procedure be followed. The Service Manual advises to disconnect the
battery before servicing the audio unit. Failure to follow this instruction, can result in a customer
concern of the backup camera becoming inoperative since the service. The reason, when connecting
power to the unit, a self-check is performed. If the backup camera has not been connected yet, the
unit assumes there is no back up camera and renders it inoperative.
RECOMMENDATION: A quick x for this condition is to remove and reinstall the transit (PDI)
fuse or remove and reinstall the negative battery terminal. The situation can be avoided completely by
following the Service Manual and disconnecting the battery before starting the service.
IMPORTANT CAUTIONS:
• If swapping an audio system for diagnostic purposes, be sure the DCM remains with the original
vehicle or network communications will be severed.
• The SXM ESN is assigned by VIN. Moving audio units permanently between vehicles will
disrupt the customer’s SXM services.
Below is an image of what the screen will look like if a line check is performed before the issue is
corrected:

Bulletin Number: 15-221-18R; Revised 02/12/21 Page 13 of 45
Continued...
A. Go to the Dealer Settings screen by holding the HOME button and pressing the TUNE knob 6
times.
B. Select “Connection”.
C. Conrm if the “Rr_CAM” shows “OK”. (Please take a photo of the screen)
CONDITION# 1.3 On vehicles equipped with reverse automatic braking (RAB), a red area
appears in backup camera display:
CAUSE: If a customer states they see a red box or area in their backup camera display, the system is
most likely operating as designed. Always perform a visual check of the sensors on the rear bumper
rst. If any of the sensors are covered over or obstructed by ice and / or snow, the RAB system may
not function properly and the red area shown in the example photo below will most likely appear.
RECOMMENDATION: When this condition occurs, the RAB system is unable to properly
dierentiate between what really is an obstacle and what is not. In the image below, the sensor is iced
over and the red area is displayed with no obstacle present. The Owner’s Manual provides a list of
other potential causes for this condition to occur.

Bulletin Number: 15-221-18R; Revised 02/12/21 Page 14 of 45
Continued...
CONDITION# 1.4 Orange park assist lines on the backup camera not moving or no longer
present:
CAUSE: Park assist lines position is reecting the steering angle. If the data is not supplied to the
head unit from CAN bus or the data supplied is wrong, the lines position is not changing. Park assist
lines display could be turned o via head unit setup.
RECOMMENDATION: Conrm the guide line settings and steering angle line data to determine
the reason for concern.
Select camera setting option to verify the CONDITION# 1.4 and use Factory Settings/Camera Setting
option to verify setup:

Bulletin Number: 15-221-18R; Revised 02/12/21 Page 15 of 45
Continued...
The steering angle reading is shown on the photo below (“Steering 326.9 deg”).
Rotate the steering wheel to conrm the number is changing with the steering wheel rotating.
Clock2.0
CONDITION# 2.1 Display audio (non-navigation),clock not synchronized (2016 Dec TechTIPS):
CAUSE: NOTE: This information is applicable to iPhone (IOS) users only. If a customer states
the time displayed on their iPhone is not synchronized with the instrument panel clock display, the
information below is an easy solution. Always ensure the latest software version is installed.
RECOMMENDATION: First, select the setting mode for the clock by following these steps:
• Press the “Home” button on the audio unit display.
• Press “Settings”
• Press “Vehicle”
• Select “Clock Adjustment”
• Select “Auto”

Bulletin Number: 15-221-18R; Revised 02/12/21 Page 16 of 45
Continued...
Once “Clock Adjustment” is set to “Auto”, the iPhone “Show Notications” setting must also be
conrmed as set to ON following the steps below.
• From the iPhone Home screen, tap “Settings”.
• From the Settings menu, tap “Bluetooth” and make sure it is set to “On”.
• Select the device being used (in this case, SUBARU BT) then tap on the blue i icon to dis-
play the device options list.
• Once “Show Notications” is switched on, the device and vehicle clocks will synchronize
automatically.

Bulletin Number: 15-221-18R; Revised 02/12/21 Page 17 of 45
Continued...
• Once “Show Notications” is switched on, the device and vehicle clocks will synchronize
automatically.
Please remember to review TSB 15-229-18: “Clock-Related Concerns and Troubleshooting” for
additional reference details.
CONDITION# 2.2 Clock Setting Information (December 2016 TechTIPS):
CAUSE: With the release of the 2017 Impreza Harman Gen 3 SUBARU STARLINK™ 6.5”
Multimedia System and SUBARU STARLINK™ 8.0” Multimedia Navigation systems, there have
been inquiries about the clock adjustment. There are two dierent modes of adjustment available:
Automatic and Manual. Figure 1 shown here is an excerpt from the 2017 Impreza Owner’s Manual
describing both modes.
RECOMMENDATION: Automatic setting of the clock is accomplished dierently between the
navigation and non-navigation systems. As shown above, the navigation system will automatically set
the time according to GPS location. Non-navigation systems utilize a paired smartphone connected
via Bluetooth to accomplish the automatic setting. During the PDI process, it is recommended to
manually set the clock on non-navigation models. This will ensure the correct time is displayed
and allows the opportunity to show the customer the automatic feature should they choose to use it.
Please review the Owner’s Manual for the applicable manual clock setting procedure.
Please remember to review TSB 15-229-18: “Clock-Related Concerns and Troubleshooting” for
additional reference details.
Head Unit or Display On/Off3.0
CONDITION# 3.1 Audio unit stays powered up after key o (2017 Feb TechTIPS):
CAUSE: All the new 2017MY Impreza audio systems include a feature where the audio system stays
powered for a period of time after the ignition is switched OFF. If the vehicle has been equipped with
the accessory Rockford Fosgate audio amplier, some confusion may arise when comparing audio

Continued...
unit operation of one Impreza to another. Although the audio unit will continue to operate after the
ignition is switched OFF on all models, the power supply for the accessory amplier is switched o
along with the ignition resulting in the loss of audio output. This may cause confusion for customers
when seeing the audio unit appear to be operating but not hearing any audio output.
NOTE: Later versions of the Rockford Fosgate amplier used in 2018 MY vehicles no longer share
this characteristic. Vehicles / audio systems equipped with these enhanced ampliers function like
those equipped with factory-installed ampliers.
RECOMMENDATION: Be advised, this is a normal operating characteristic and no attempt
should be made to repair or replace any of the system components. This operating characteristic
is also briey described on pg. 118 of the Multimedia System guide contained in the Owner
Information Kit as shown here.
Please remember to review TSB 15-211-17R: “Reprogramming File Availability for Additional
Optimization of Harman Gen 3 Audio and Navigation Head Units” for additional reference details.
CONDITION# 3.2 Keeping the Display OFF during loading:
CAUSE: Customer asks to keep the display o (black screen) following ignition ON.
RECOMMENDATION: Press and Hold Power/Volume knob for 4 seconds prior shutting o
engine.
NOTE: Audio will still play following ignition ON, but display will remain blank. If customer is
concerned about volume as well as display, see CONDITION# 3.3 for more details.
CONDITION# 3.3 Keeping display and Audio OFF during loading:
CAUSE: Customer asks to keep the display OFF (black screen) and audio muted following the
ignition ON step.
RECOMMENDATION: This condition has been addressed by software update released Summer,
2018. Until the software update is installed, clear the condition by performing a capacitive discharge
or exchange the head unit.
Please remember to review TSB 15-211-17R: “Reprogramming File Availability for Additional
Optimization of Harman Gen 3 Audio and Navigation Head Units” for additional reference details.

Audio Output4.0
CONDITION# 4.1 Audio Volume is turned to MAX when monitoring infotainment data
monitor (March 2017 TechTIPS):
CAUSE: If you are monitoring the Infotainment System Data Monitor and the volume level display
(Figure below) appears showing the volume level increasing but the sound level remains the same,
this is a normal operation of the Harman unit.
RECOMMENDATION: When a Technician accesses the Infotainment System Data Monitor, the
unit enters “Diagnostic Mode” and the volume level will be displayed in this manner. No repairs
should be performed to address this concern as it is a normal operating characteristic.
CONDITION# 4.2 No audio sound after turning o the ignition:
CAUSE: The audio signal is routed through the Amplier, which boosts the signal and sends the
converted data to output through the speakers.
Two lines are used for the interrupt, where one is for NAV and the other one is for the phone. Two are
used for CAN, while the other two are used for entertainment (radio, media, etc.).

Bulletin Number: 15-221-18R; Revised 02/12/21 Page 20 of 45
Continued...
RECOMMENDATION: SOA oers an accessory called the Rockford Fosgate Premium Audio
Upgrade. When this accessory is installed, although the head unit will continue to operate after the
ignition is turned o, the power supply for the accessory amplier is switched o, resulting in the
