CHANGE ENGINE OIL
The IPC illuminates the CHANGE ENGINE OIL indicator when the powertrain control module (PCM) determines that the engine oil should be changed. The IPC receives a class 2 message from the PCM indicating the remaining oil life percent. 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 GAGES
The IPC illuminates the CHECK GAGES indicator under the following conditions:
| • | The engine coolant temperature exceeds 125°C (257°F). The IPC receives a class 2 message from the PCM indicating the engine coolant temperature. |
| • | The engine oil pressure is low. The IPC receives a class 2 message from the PCM indicating the engine oil pressure. |
| • | The IPC has not been programmed after an IPC replacement. Refer to Service Programming System (SPS) in Programming. |
CHECK OIL LEVEL
The IPC illuminates the CHECK OIL LEVEL message in the driver information center (DIC) when the powertrain control module (PCM) detects a low engine oil level condition. The PCM only monitors the oil level switch signal circuit for a brief period between key on and ignition crank. The IPC receives a class 2 message from the PCM requesting illumination.
FUEL LEVEL LOW
The IPC illuminates the FUEL LEVEL LOW message in the driver information center (DIC) 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 fuel level percent.
ICE POSSIBLE
The IPC illuminates the ICE POSSIBLE message in the driver information center (DIC) when the outside air temperature drops below 4°C (39°F). The IPC receives a class 2 message from the body control module (BCM) indicating the outside air temperature.
OIL PRESSURE LOW STOP ENGINE
The IPC illuminates the OIL PRESSURE LOW STOP ENGINE message in the driver information center (DIC) when the PCM detects a low oil pressure condition with the signal circuit low. The IPC receives a class 2 message from the PCM requesting illumination.
OVERSPEED
The IPC illuminates the OVERSPEED indicator when the IPC detects that the vehicle speed is more than 120 km/h (75 mph).
PROGRAM CLUSTER
The IPC illuminates the PROGRAM CLUSTER message in the driver information center (DIC) when the IPC has not been programmed after an IPC replacement. Refer to Service Programming System (SPS) in Programming.
