ON-BOARD DIAGNOSTIC SYSTEM FUNCTION [CAR-NAVIGATION SYSTEM]

id0920001018b2

• 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 car-navigation 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 twenty DTCs. If another malfunction is detected when twenty 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 switch the ignition to off or disconnecting the negative battery cable. The procedure is mentioned in the Workshop Manual.


Display function

• When the self-diagnostic function is activated, the multi information display displays the DTC stored in the memory.
• The DTC consists of the following codes:
― Device code
― Error code
― Malfunction contents
― Error-detection date and time
• Refer to the Workshop Manual for the display method.
