Diagnosis description : malfunction indicator lamp (MIL)

When emissionrelated ECU detects a malfunction in the emission control systems components and/or the powertrain control components (which affect vehicle emissions), it turns on/blinks MIL to inform the driver that a malfunction has been detected.

    1.   The MIL illuminates when ignition switch is turned ON (engine is not running).

NOTE:

Check the MIL circuit if MIL does not illuminate.

    2.   When the engine is started, the MIL should go off.

NOTE:

If MIL continues to illuminate/blink, perform selfdiagnoses and inspect/repair accordingly because an emissionrelated ECU has detected a malfunction in the emission control systems components and/or the powertrain control components (which affect vehicle emissions).
