Code P0650 2015 Chevrolet Silverado Description

The Malfunction Indicator Lamp (MIL) illuminates to inform the driver that an emission system fault has occurred, and 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. The Diagnostic Trouble Code (DTC) will be set when the ECM detects low voltage during the MIL control circuit driver OFF state. This indicates either a shorted to ground or an open MIL control circuit.
