How to Check the HandsFreeLink System Condition

NOTE:

Check the vehicle battery condition first (see BATTERY TEST ).
Make sure the audio system or the navigation system anti-theft code is entered.
The self-diagnostic function can only be initiated while the HFL is in its idle state.

Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
Press and hold the HANG-UP button (A) or the HFL BACK button (B) for more than 5 seconds.

The HFL system starts the self-diagnosis, the following will occurs:
- If the HFL system is OK, and there are no HFL DTCs, the HFL system says, "The HFT is OK."
- If there are any HFL DTCs stored, the HFL system says, "The HFT is NG."

The self-diagnosis ends if the HFL system returns to its idle state.
