Malfunction Indicator Lamp (MIL)

WARNING: This page is about a different car, the 2019 Nissan NV3500 HD, 2019 Nissan NV2500 HD, and 2019 Nissan NV1500. 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 Component Function Check .
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).
