Circuit/System Description

WARNING: This page is about a different variant/trim than selected.

The malfunction indicator lamp (MIL) illuminates to inform the driver that an emission system fault has occurred and that the powertrain control system requires service. Ignition voltage is supplied directly to the MIL. The engine control module (ECM) turns the MIL ON by grounding the MIL control circuit when the emission system fault occurs. Under normal operating conditions, the MIL should be ON only when the ignition is ON and the engine is OFF.
