ON-BOARD DIAGNOSTIC SYSTEM FUNCTION

id092000101800

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.
