How to Troubleshoot the HandsFreeLink System
Self-Diagnostic Function
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), or press the engine start/stop button to select the ON mode.
2. Press and hold the HANG-UP button (A) or the HFL BACK button (B) 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 starts after you press and hold the HANG-UP button or the HFL BACK button for 5 seconds, and ends if the HandsFreeLink control unit returns to its idle state.
Glossary of Terms
Auto Answer
This cell phone setting forces incoming calls to automatically be answered by the handset. Disable this feature on the cell phone when using the HFL system, as it may interfere with the HFL system answering incoming calls. Set the cell phone setting to:
- Send Only
- Any Key
- Multi-Key answer
Answer Options
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 cell phone can affect inbound calls on the HFL system.
Authorized Connection
This cell phone setting allows the cell 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 cell phone to properly route sound to the HFL system.
Bluetooth Power
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.
Discovery Mode
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 cell phone during the pairing process.
HFL Button
- TALK button (A) or the HFL TALK button (B): This button activates the voice control system and is used for all voice commends. Press and release it, wait for a beep, and give a voice command.
- BACK button (C) or the HFL BACK button (D): This button has the same function as the CANCEL button. When you press and release it, the current voice command is canceled and the display returns to the previous screen.
- PICK-UP button (E) or the HFL TALK button: This button is used to answer incoming calls or to make outgoing calls. You can also go directly to the Cellular Phone screen by pressing this button.
- HANG-UP button (F) or the HFL BACK button: This button is used to end a call.
Hard Reset (cellular phone)
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 cell phone owner's manual for more information).
Linking
This is when your paired cell phone is actively ready to use the HFL system. You can pair up to six cell phones to the HFL system, but only one cell phone can be linked at a time. If two paired cell phones are in the vehicle, only the cell phone that is linked can use the HFL system and functions. The second cell phone must be used as a normal handset.
Pairing
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.
Soft Reset (cellular phone)
This helps to restore the basic functions of the cell phone. To do a soft reset, turn the cell phone power off, remove and reinsert the cell phone battery, then turn the cell phone back on. See the cell phone user manual for more information.
Software Version
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.
