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"
