2. Display of diagnostic trouble code (DTC) by diagnosis lamp
Only when diagnostic trouble code (DTC) occurs during engine operation, diagnosis lamp is ON.
During engine stop, diagnostic trouble code (DTC) displays both present and past diagnostic
trouble code (DTC) by diagnosis lamp blinking pattern (flash code).
3. In case that past diagnostic trouble code (DTC) is memorized
It displays three times memorized trouble code. In case that more than two trouble codes are
memorized, it displays them three times each in numerical order. After they are displayed in one
round, they are displayed in numerical order again. This display continues while diagnosis switch
is being pressed.
4. In case that no diagnostic trouble code (DTC) is memorized
While you pressing diagnosis switch, diagnosis lamp - repeat continuously “the lighting 0.3 seconds
2.4 seconds off”.
5. Reading diagnostic trouble code (DTC) by diagnosis tool
It is possible to read diagnostic trouble code (DTC), using diagnosis tool.
