CHANGE ENGINE OIL
The IPC illuminates the CHANGE ENGINE OIL indicator in the message center when the PCM determines that the engine oil should be changed. The IPC receives a class 2 message from the PCM requesting illumination. 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 in Maintenance and Lubrication.
CHECK ENGINE OIL LEVEL
The IPC illuminates the CHECK ENG OIL LEVEL indicator in the message center when the PCM detects a low engine oil level condition and the engine oil level switch signal circuit is high. An open engine oil level switch indicates a low engine oil level and a closed engine oil level switch indicates the engine oil level is in the normal range. The CHECK ENG OIL LEVEL indicator illuminates for 60 seconds at the start of each ignition cycle when a low engine oil level condition is present. The IPC receives a class 2 message from the PCM requesting illumination.
CHECK ENGINE OIL PRESSURE
The IPC illuminates the CHECK ENG OIL PRESSURE indicator in the message center when the IPC detects low oil pressure from the engine oil pressure sensor signal.
LOW FUEL
The IPC illuminates the LOW FUEL indicator in the message center when the IPC detects that the fuel level is less than a pre-determined value. The IPC receives a class 2 message from the PCM indicating the fuel level percent.
Over Speed Indicator
The IPC illuminates the OVER SPEED indicator in the message center when the BCM detects the vehicle speed is above 120 km/h (75 mph). The IPC receives a class 2 message from the BCM requesting illumination of the over speed indicator.
WATER IN FUEL
The IPC illuminates the WATER IN FUEL message in the driver information center (DIC) when the powertrain control module (PCM) detects a low signal from the water in fuel sensor. The IPC receives a class 2 message from the PCM requesting illumination.
