DIC WARNING MESSAGES

CHANGE ENGINE OIL NOW
The IPC illuminates the CHANGE OIL NOW message in the driver information center (DIC) when the powertrain control module (PCM) determines that the engine oil needs to be changed now. The PCM sends a class 2 message to the IPC requesting illumination. After the oil is changed, reset the engine oil monitor. Refer to GM Oil Life System - Resetting in Maintenance and Lubrication.

CHANGE ENGINE OIL SOON
The IPC illuminates the CHANGE ENGINE OIL SOON message in the driver information center (DIC) when the powertrain control module (PCM) determines that the engine oil should be changed in the near future.The PCM sends a class 2 message to the IPC requesting illumination. After the oil is changed, reset the engine oil monitor. Refer to GM Oil Life System - Resetting in Maintenance and Lubrication.

CHECK GAGES
The IPC illuminates the CHECK GAGES message when the IPC illuminates any following indicators.
- Charging system
- Engine coolant temperature
- Low coolant
- Low fuel
- Low oil pressure

HIGH OIL TEMPERATURE, REDUCE ENGINE RPM
The IPC illuminates the HIGH OIL TEMPERATURE message and then the REDUCE ENGINE RPM messages in the driver information center (DIC) in 3
second intervals if the IPC detects that the engine oil temperature exceeds 160°C (320°F). The IPC monitors the engine oil temperature signal circuit to determine the engine oil temperature. A low resistance indicates high engine oil temperature.

KM/H AND MPH INDICATOR(s)
km/h: The IPC illuminates the km/h indicator when the IPC detects that metric units have been requested. The IPC monitors the signal circuit of the ENG/MET switch. The IPC sends a class 2 message indicating the requested units to the head up display (HUD).

MPH: The IPC illuminates the MPH indicator when the IPC detects that English units have been requested. The IPC monitors the signal circuit of the ENG/METswitch. The IPC sends a class 2 message indicating the requested units to the head up display (HUD).

LOW FUEL
The IPC illuminates the LOW FUEL message in the driver information center (DIC) when the PCM 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.

LOW OIL LEVEL
The IPC illuminates the LOW OIL LEVEL message in the driver information center (DIC) when the powertrain control module (PCM) detects low engine oil level, and the signal circuit is high. The PCM only monitors the signal circuit of the engine oil level switch for a brief period when the key moves from ON to START. The IPC receives a class 2 message requesting illumination from the PCM.

LOW OIL PRESSURE
The IPC illuminates the LOW OIL PRESSURE message in the driver information center (DIC) when the PCM detects low engine oil pressure, and the signal circuit is low. The IPC receives a class 2 message requesting illumination from the PCM.

RESERVE FUEL
The IPC illuminates the RESERVE FUEL message driver information center (DIC) when the PCM detects the following conditions:
- The fuel level is less than 12 L for 60 seconds.
- The fuel level is less than 12 L for 5 seconds immediately after the ignition is turned ON, and the vehicle speed is less than 1 MPH.
The IPC receives a class 2 message requesting illumination from the PCM.

SERVICE VEHICLE SOON
The IPC illuminates the SERVICE VEHICLE SOON message in the driver information center (DIC) when the powertrain control module (PCM) detects certain malfunctions that are not related to the emissions system. The IPC receives a class 2 message requesting illumination from the PCM.
