Self-Diagnostic Function

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 ACC (I).
2. Press and hold the HFL BACK button for more than 5 seconds.
3. When the HandsFreeLink system enters the self-diagnostic function, the following will occur.
- If the system has not completed testing for DTCs, the HandsFreeLink control unit audibly outputs "The hands free system test is in progress".
- If there is no DTC, the HandsFreeLink control unit audibly outputs "The hands free system is OK".
- If there is any DTC, the HandsFreeLink control unit audibly outputs "The hands free system needs to be serviced".

NOTE:
- The self-diagnostic function can only be initiated while the HFL 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.
