October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.

Code 12 - System Normal

Code No. 12 is always displayed when the key is ON and the engine is not running and it only means that the engine is not running. This code No. 12 is not stored in memory.

NOTE: If the signal code No. 12 only is displayed when the function key is operated after clearing the memory, it indicates that the ECM electrical circuits and self diagnosis system are functioning normally.
