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.
