Service codes are shown by a series of long and short blinks of the yellow engine warning indicator light (LED), and the number of two digits on the display, as shown below. When there are a number of problems, all the service codes can be stored and the display will begin starting from the lowest number service code in the numerical order. Then after completing all codes, the display is repeated until ignition switch is turned off.
