- Using a scan tool, perform the Powertrain Control Module (PCM) Key ON Engine OFF (KOEO) self-test.
- Are any Powertrain Control Module (PCM) Diagnostic Trouble Codes (DTCs) recorded?
- Yes: REFER to the appropriate Powertrain Control/Emissions Diagnosis (PC/ED) manual INTRODUCTION - GASOLINE MODELS .
- No: GO to 2 on page 2.
- RETRIEVE THE RECORDED Diagnostic Trouble Codes (DTCs) FROM THE Instrument Panel Cluster (IPC) SELF-TEST
- Using a scan tool, perform the Instrument Panel Cluster (IPC) self-test.
- Is Diagnostic Trouble Code (DTC) U0100:00 recorded?

- CARRY OUT THE Instrument Panel Cluster (IPC) Malfunction Indicator Lamp (MIL) ACTIVE COMMAND USING THE SCAN TOOL
- Ignition ON.
- Using a scan tool, view the Instrument Panel Cluster (IPC) Parameter Identifications (PIDs).
- Select the Instrument Panel Cluster (IPC) Malfunction Indicator Lamp (MIL) Parameter Identification (PID). Command the Malfunction Indicator Lamp (MIL) on and off. Observe the Malfunction Indicator Lamp (MIL).
- Does the Malfunction Indicator Lamp (MIL) illuminate when selected on and turn off when selected off?
- Yes:
If the Malfunction Indicator Lamp (MIL) is never on, the system is operating correctly at this time.
If the Malfunction Indicator Lamp (MIL) is always on, INSTALL a new Powertrain Control Module (PCM). REFER to POWERTRAIN CONTROL MODULE (PCM) .
- No: INSTALL a new Instrument Panel Cluster (IPC). REFER to INSTRUMENT PANEL CLUSTER (IPC) .
