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."
- The self-diagnostic function ends when the units return to idle state.
  NOTE: The self-diagnostic function can only be initiated while the HFL is in an idle state.
