•	Diagnostic Procedure Instructions provide an overview of each diagnostic category.

DTC Descriptors

DTC P0650: Malfunction Indicator Lamp (MIL) Control Circuit Low Voltage

DTC P1650: Malfunction Indicator Lamp (MIL) Control Circuit High Voltage

Diagnostic Fault Information

Circuit	Short to Ground	Open/High Resistance	Short to Voltage	Signal Performance
MIL Voltage Supply	P0650	P0650	--	--
MIL Control	P0650/MIL ON	P0650	P1650	--

The malfunction indicator lamp (MIL) is located on the instrument panel cluster (IPC). The MIL informs the driver that an emission system fault has occurred and that the engine control system requires service. The control module monitors the MIL control circuit for conditions that are incorrect for the commanded states of the MIL.

Conditions for Running the DTC

•	The ignition is ON or the engine is operating.

•	The DTCs runs continuously once the above conditions are met.

Conditions for Setting the DTC

P0650

The engine control module (ECM) detects the MIL control circuit is open or shorted to ground.

P1650

The ECM detects the MIL control circuit is shorted to voltage.

Action Taken When the DTC Sets

DTC P0650 and P1650 are Type B DTCs.

Conditions for Clearing the DTC

DTC P0650 and P1650 are Type B DTCs.

Circuit/System Verification

Turn ON the ignition. Command the MIL ON and OFF with a scan tool. The MIL should turn ON and OFF when commanded.
If the vehicle passes the Circuit/System Verification Test, then operate the vehicle within the conditions for running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records Data List.

Circuit/System Testing

If any other IPC indicators or gages are inoperative, refer to Symptoms - Instrument Panel, Gages and Console .
Ignition OFF, disconnect the ECM harness connector.
Ignition ON, connect a 3-amp fused jumper wire between the MIL control circuit and the negative terminal of the battery. The MIL should illuminate.

⇒	If the MIL does not illuminate, test the MIL control circuit for a short to voltage, short to ground, or an open/high resistance. If the circuit test normal, replace the IPC/bulb.

If all circuits/connections test normal, replace the ECM.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
