Malfunction Indicator Lamp: Description
WARNING: This page is about a different car, the 2012 Infiniti FX35. However, it is still accessible from the selected car via links, so may be relevant.
When emission-related 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.
- The MIL illuminates when ignition switch is turned ON (engine is not running).NOTE: Check the MIL circuit if MIL does not illuminate. Refer to "DIAGNOSIS PROCEDURE ".
- When the engine is started, the MIL should go off.
NOTE: If MIL continues to illuminate/blink, perform self-diagnoses and inspect/repair accordingly because an emission-related ECU has detected a malfunction in the emission control systems components and/or the powertrain control components (which affect vehicle emissions).
