NKS002Q3

When the hands-free phone system has a malfunction, check if the cellular phone and the communications
circuit between control units have a malfunction (Refer to

 ), and then start

diagnoses. Also, when starting diagnoses, turn on the cellular phone to establish connection with the Blue-
tooth

®

Performs the unit self-diagnosis and antenna diagnosis, and informs results with the indicator and voice
guidance.

●

Informs vehicle speed pulse count from the time of key switch ON with voice guidance, and enables to
