Outgoing CallsClearing the HFL System
23-367
If a client says that they cannot place a call using the
HFL system, ask if the call was initiated through the HFL
system or the cell phone itself.
IfthecallisplacedbytheHFLsystem:
1. Make sure the Bluetooth feature is turned on in the cell phone.
2. Make sure the cell phone is paired to the HFL system and linked.
3. Make sure the client is pressing the HFL TALK button before each command and going through
the calling process correctly.
4. Make sure the client is pressing the HFL TALK button and not the HFL BACK button or the
navigation buttons.
5. Check if the cell phone has an Authorized Connections or Trusted option.
6. Do a soft reset to the cell phone.
If the call is placed by the cell phone:
The call will remain on the handset until you transfer it
over to the HFL system. To continue the call on the HFL
system, you must use the Transfer command by
pressing and releasing the HFL TALK button during an
active call and saying ‘‘Transfer.’’ The client can now
continue the call using the HFL system. NOTE:
 This operation clears the HFL system of all passcode(s), any paired phones, and all names in the
HFL phonebook.
 Clearing the HFL system is recommend before selling the vehicle.
 If the system is locked and the pass code is lost or forgotten, see the symptom troubleshooting.
1. Press and release the HFL TALK button. After the beep, say ‘‘System clear’’ and the HFL system
responds, ‘‘This process will clear all paired phone,
clear all entries in the phonebook, clear the
passcode and restore all defaults in the system
setup. Is this what you would like to do?’’
2. Press and release the HFL TALK button. After the beep, say ‘‘Yes’’ and the HFL system responds,
‘‘Preparing to clear all paired phone, all phonebook
entries, the passcode. This may take up to 2
minutes to complete’’.
3. Press and release the HFL TALK button. After the beep, say ‘‘OK’’ to proceed, or say ‘‘Go back’’ or
‘‘Cancel’’.
4. If you said ‘‘OK’’, after a short period of time, the HFL system responds, ‘‘System has been cleared.
Returning to the main menu, the Clearing HFL
system procedure is now complete’’.

General Troubleshooting Information (cont’d)
NOTE: This procedure should be used only if HDS is
unavailable.
To run the self-diagnostic function, do the following:
1. Turn the ignition switch to ON (II).
2. Press and hold the HFL BACK button for more than 5 seconds.
3. When the HandsFreeLink system enters the self- diagnostic function, the following will occur.
 If the system has not completed testing for DTCs, the HandsFreeLink system says ‘‘The hands free
system test is in progress’’.
 If there is no DTC, the HandsFreeLink system says ‘‘The hands free system is OK’’.
 If there is any DTC, the HandsFreeLink system says ‘‘The hands free system needs to be
serviced’’.
NOTE:  The self-diagnostic function can only be initiated while the HFL is in its idle state.
 The self-diagnostic function is considered start once the 5 seconds press and hold is detected, and ends
when the units returns to idle state. This cell phone setting forces incoming calls to
automatically be answered by the handset. Disable this
feature on the phone when using the HFL system, as it
may interfere with the HFL system answering incoming
calls. Set the phone setting to:
SendKey
AnyKey
 Multi Key answer
These cell phone settings allow you to select how you
would like to answer an incoming call on the handset.
The answer option in the phone can affect inbound calls
on the HFL system.
This cell phone setting allows the phone to connect
automatically with the HFL system without prompting
the client for permission to connect. In some instances,
it can affect the ability of the phone to properly route
sound to the HFL system.
This cell phone function enables or disables the
Bluetooth application. When using a hands-free device
such as HFL, the Bluetooth application needs to be
enabled.
You need to have the cell phone in Discovery Mode to
allow other devices with Bluetooth capabilities (such as
the HFL system) to find the phone during the pairing
process.
A client gets these ringtones from an outside source,
such as the internet or a mobile phone store.

 HFL TALK button (A): Use this button on the steeringwheel to give commands. Press the button before a
voice command is given.
 HFL BACK button (B): Use this button on the steering wheel to end a call or return to a previous prompt in
the HFL menu. Pressing the button twice or holding it
down returns you to the HFL main menu.
Hard resets clear the saved settings in the cell phone
and restores it to the factory defaults. A hard reset
should be done only as a last resort (see the sell phone
owner’s manual for more information).
This is when your paired phone is actively ready to use
the HFL system. You can pair up to six phones to the
HFL system, but only one phone can be linked at a time.
If two paired phones are in the vehicle, only the phone
that is linked can use the HFL system and functions. The
second phone must be used as a normal handset. A description for linking two Bluetooth devices together.
In this case, you are linking a cell phone with the HFL
system. After the pairing process is complete, the
devices are able to recognize each other and
communicate wirelessly via Bluetooth.
This helps to restore the basic functions of the phone.
To do a soft reset, turn the phone power off, remove
and reinsert the cell phone battery, then turn the phone
back on.
This refers to the software version loaded in the cell
phone. The software version that was tested and
determined to be compatible with the HFL system may
be listed on the HFL website. Not all software versions
are compatible with the HFL system.
These ringtones come factory-installed on the cell
phone.

HFL System Troubleshooting
NOTE:
 You must be able to duplicate the client’s concern to successfully diagnose the problem.
 Always use the client’s phone.
 Make sure the phone is approved and configured correctly. Online, go to www.acura.com/handsfreelink, or call the HFL support desk at 888-528-7876.
1. Connect the HDS to the DLC.
2. Turn the ignition switch to ON (II).
3. Check for DTCs.
Repair the indicated DTCs and recheck.
Go to step 4.
4. Try to duplicate the problem.
Go to step 5.
The system is OK at this time.
5. Pair the phone to a known-good vehicle (same model, year, and trim), and tryduplicate the problem.
Call the HFL support desk at 888-528-7876 to make sure the phone is configured correctly and has the
correct software. If the phone is configured correctly, it is either a characteristic of the HFL system, or a
characteristic of the particular approved phone being used. Explain to your client that this is a system
characteristic. Another phone from the approved phone list may give more favorable results.
Substitute a known-good HandsFr eeLink control unit and recheck. If the problem goes away, replace the
original HandsFreeLink control unit.
Are any DTCs indicated?
