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/BACK button on the HFL switch for 5 seconds, and ends if the HandsFreeLink control unit returns to its idle state.

Turn the ignition switch to ON (II).
Press and hold the Hang-up/BACK button for more than 5 seconds.
When the HFL system enters the self-diagnostic function, the following will occurs:
- If the HFL 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.". Check for the HFL DTCs.
