ON-BOARD DIAGNOSTIC SYSTEM FUNCTION [AUDIO (STANDARD AUDIO)]
id0920001018a6
•
The on-board diagnostic system has a self-diagnostic function and diagnostic assist function to help
technicians locate malfunctions.
Self-diagnostic Function
Malfunction detection function
•
The malfunction detection function detects malfunctions occurring in the 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 Service
Section.
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)
