ON-BOARD DIAGNOSTIC SYSTEM FUNCTION [CAR-NAVIGATION SYSTEM]
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 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:
— Device code
— Error code
— Malfunction contents
— Error-detection date and time
Refer to the Workshop Manual for the display method.
