OPERATION
The ECU stores a code for the fault. Immediately after the ignition switch is turned on, the MIL light will light for 2.5 seconds to indicate that the light
operates normally. When an irregular signal returns to normal the MIL light goes out. Also, when the ignition switch is turned off, the light goes out. If
the engine is re-started the light will not come back on until the fault re-occurs, but a code will be stored in the ECU memory.
