FOREWORD [Bluetooth SYSTEM (HANDS-FREE TELEPHONE SYSTEM)]

On-board diagnostic function 

• The on-board diagnostic function consists of the following functions: A malfunction detection function, which detects overall malfunctions in the audio system-related parts; a memory function, which stores detected DTCs; and a display function, which indicates system malfunctions via a DTC display.
• The memory function converts a malfunction detected by the malfunction detection function to a DTC and stores it. The error currently occurring is stored as a present malfunction. Up to 5 DTCs can be stored as a present malfunction.
• There are two methods for reading and clearing DTCs. They include activation of the on-board diagnostic test mode of the on-board diagnostic function, which is operated using the audio unit, and the M-MDS. The displayed DTCs differ depending on whether the on-board diagnostic test mode or the M-MDS method is used. Additionally, because some DTCs are not displayed in the on-board diagnostic test mode, use the M-MDS before performing the procedure.

  On-board diagnostic test mode 

  • To display DTCs on the information display that have been recorded in the memory function, activate the on-board diagnostic function by operating the audio unit.

    Using the M-MDS 

  • When a DTC inspection is performed using the M-MDS, the malfunction diagnostics for the audio system and Bluetooth system (hands-free telephone (HF/TEL) system) is initiated. A maximum of 5 DTCs detected by the malfunction diagnostics are displayed.

  Diagnostic assist function 

• The diagnostic assist function enables verification of the connection condition of the Bluetooth system (hands-free telephone (HF/TEL) system) related parts and their specification. The password for the Bluetooth system (hands-free telephone (HF/TEL) system), which is set by the user, can also be reset.
