ON-BOARD DIAGNOSTIC SYSTEM FUNCTION [AUDIO SYSTEM]

id0920001018a1

Self-diagnostic Function

Malfunction detection function

•  The malfunction detection function detects malfunctions occurring in the audio system.

Memory function

•  The memory function detects a malfunction, changes it to a DTC, and stores it in the memory. The memory can store a maximum of three DTCs. If another malfunction is detected when three DTCs are already stored, the memory function clears the oldest DTC and stores the new one.

•  Once a DTC is stored, it can only be cleared by the designated procedure; not by turning the ignition switch to the LOCK position or disconnecting the negative battery cable. The procedure is mentioned in the Workshop Manual.

Display function

•  When the self-diagnostic function is activated, the information display displays the DTC stored in the memory.

•  The DTC consists of the following codes:

―  Supplier code (indicates manufacturer)

―  Device code (indicates malfunctioning part)

―  Error code (indicates malfunction description)

•  Refer to the Workshop Manual for the display method.
