Initial Inspection and Diagnostic Overview

FOREWORD [Bluetooth SYSTEM (HANDS-FREE TELEPHONE (HF/TEL) SYSTEM)]

- The Bluetooth system (hands-free telephone (HF/TEL) system) has an on-board diagnostic function and diagnostic assist function to facilitate Bluetooth system (hands-free telephone (HF/TEL) system) diagnosis.

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 five 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 or car-navigation 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 multi 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, Bluetooth system (hands-free telephone (HF/TEL system), and the SIRIUS satellite radio system is initiated. A maximum of 10 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.
