Circuit/System Verification
1. Ignition ON, command the MIL ON and OFF with a scan tool. The MIL should turn ON and OFF as commanded.
2. Engine idling, command the MIL ON and OFF with a scan tool while observing the following control circuit status parameters:
* MIL Ckt Short Gnd Test Status
* MIL Ckt Open Test Status
* MIL Ckt Short Volts Test Status
Each parameter should display OK or Not Run.
3. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed
from the Freeze Frame/Failure Records data.
Circuit/System Testing
1. If any other instrument panel cluster (IPC) indicators or gauges are inoperative, refer to Instrument Cluster Gauges Inoperative (See:
Instrument Panel, Gauges and Warning Indicators/Testing and Inspection/Instrument Cluster Gauges Inoperative).
2. Ignition OFF, disconnect ECM X1 harness connector. Ignition ON, the MIL should not illuminate.
瀚慖f the MIL is illuminated, test the MIL control circuit terminal X1-68 for a short to ground. If the circuit tests normal, replace the IPC.
3. Ignition ON, connect a 3 A fused jumper wire between the MIL control circuit terminal X1-68 and ground. The MIL should illuminate.
瀚慖f the MIL does not illuminate, test the MIL control circuit for a short to voltage, or an open/high resistance. If the circuit tests normal,
replace the IPC/bulb.
4. If all circuits/connections test normal, replace the ECM.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
