ON-BOARD DIAGNOSTIC SYSTEM FUNCTION

Self-diagnostic Function

Malfunction detection function
• The malfunction detection section 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 and numbers:
— Supplier code (indicates manufacturer)
— Part number (indicates malfunctioning part)
— Error code (indicates malfunction description)
• Refer to the Service Section for the display method.
