How to Troubleshoot the HFT 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).

1. Press and hold the HFT Back button for more than 5 seconds.

1. When the Hands Free Telephone system enters the self-diagnostic function, the following will occur.
   - If there is no DTC, the Hands Free Telephone control unit audibly outputs ‘‘The hands free system is OK''.
   - If there is any DTC, the Hands Free Telephone control unit audibly outputs ‘‘The hands free system needs to be serviced''.

NOTE:

- The self-diagnostic function can only be initiated while the HFT is in its idle state.
- The self-diagnostic function is considered to start once the 5 seconds press and hold is detected, and ends when the units returns to idle state.
