ENGINE MALFUNCTION INDICATOR LAMP (MIL)

B: ACTIVATION OF CHECK ENGINE

MALFUNCTION INDICATOR

1) When the ignition switch is turned to ON (engine

OFF), the CHECK ENGINE malfunction indicator

lamp (MIL) in the combination meter illuminates.

If the MIL does not illuminate, perform diagnostics

of the CHECK ENGINE light circuit or the combina-

tion meter circuit. <Ref. to EN-54, CHECK ENGINE

MALFUNCTION INDICATOR LAMP (MIL) DOES

NOT COME ON., Engine Malfunction Indicator

Lamp (MIL).>

2) After starting the engine, the MIL goes out. If it

does not, either the engine or the emission control

system is malfunctioning.

3) If the diagnosis system senses a misfire which

could damage the catalyzer, the MIL will blink at a

cycle of 1 Hz.

4) When the ignition switch is turned to ON (engine

OFF) or to START with the test mode connector

connected, the MIL blinks at a cycle of 3 Hz.
