| The IPC displays this indicator when the ECM/PCM determines that the engine oil should be changed. Once the oil is changed, perform the engine oil monitor reset procedure in order to clear the Change Engine Oil indicator. Refer to GM Oil Life System Resetting . | ||||
| Change Fuel Filter: Fuel System Description | ||||
| |||||
| The IPC displays this indicator as determined by the ECM/PCM. The ECM/PCM monitors the engine coolant temperature sensor and the engine oil pressure sensor. When the ECM/PCM detects that the engine coolant temperature is higher than normal or the engine oil pressure is lower than normal, the ECM/PCM sends a class 2 message to the IPC requesting illumination. | ||||
| The IPC displays this indicator when the diesel p articulate filter (DPF) needs regeneration. The IPC receives a class 2 message from the ECM requesting illumination. The indicator will illuminate yellow when regeneration is required. If the DPF indicator turns red, the ECM will also request illumination of the MIL indicator. During regeneration, the ECM will request illumination of a separate green DPF indicator. | ||||

| Low Coolant Level: Cooling System Description and Operation | ||||
| The low engine oil level indicator displays in the IPC when the ECM/PCM detects a low engine oil level condition. The ECM/PCM monitors the engine oil level switch. The ECM/PCM detects that the engine oil level is low when the switch is open and the engine oil level signal circuit is high. | ||||
