DIC Warning Messages








CHANGE ENGINE OIL

The instrument panel cluster (IPC) illuminates the CHANGE ENGINE OIL message when the engine control module (ECM) determines that the engine oil should be changed. The IPC receives a class 2 message from the ECM 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.

CHANGE FUEL FILTER

The instrument panel cluster (IPC) illuminates the CHANGE FUEL FILTER messages in the driver information center (DIC) when the powertrain control module (PCM) determines that the fuel filter should be changed. The IPC receives a class 2 message from the PCM requesting illumination.

CHECK OIL LEVEL

The instrument panel cluster (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.

CNG LEVEL SHOWN

The instrument panel cluster (IPC) illuminates the CNG LEVEL SHOWN message in the driver information center (DIC) when the powertrain control module (PCM) detects that the fuel gage selector switch is pressed while the vehicle is operating on gasoline. The IPC receives a class 2 message from the PCM requesting illumination.

FUEL FILTER LIFE RESET

The instrument panel cluster (IPC) illuminates the FUEL FILTER LIFE RESET message when the fuel filter reset procedure is completed. The IPC receives a class 2 message from the engine control module (ECM) requesting illumination.

FUEL LEVEL LOW

The instrument panel cluster (IPC) illuminates the FUEL LEVEL LOW message in the driver information center (DIC) and the LOW FUEL indicator when the IPC detects that the fuel level is less than a pre-determined value. The IPC receives a class 2 message from the powertrain control module (PCM) indicating fuel level percent.

GASOLINE LEVEL SHOWN

The instrument panel cluster (IPC) illuminates the GASOLINE LEVEL SHOWN message in the driver information center (DIC) when the powertrain control module (PCM) detects that the fuel gage selector switch is pressed while the vehicle is operating on CNG. The IPC receives a class 2 message from the PCM requesting illumination.

ICE POSSIBLE

The instrument panel cluster (IPC) illuminates the ICE POSSIBLE message in the driver information center (DIC) when the outside air temperature drops below 2.5°C (36.5°F). The IPC receives a class 2 message from the HVAC control module indicating the outside air temperature.

OIL LIFE RESET

The instrument panel cluster (IPC) illuminates the OIL LIFE RESET message 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.

OIL PRESSURE LOW

The instrument panel cluster (IPC) illuminates the OIL PRESSURE LOW message in the driver information center (DIC) when the powertrain control module (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 instrument panel cluster (IPC) illuminates the OVERSPEED indicator when the IPC detects that the vehicle speed is more than 120 km/h(75 mph).

PROGRAM CLUSTER

The instrument panel cluster (IPC) illuminates the PROGRAM CLUSTER message in the driver information center (DIC) when the IPC has not been programmed after an IPC replacement.

RUNNING ON GASOLINE

The instrument panel cluster (IPC) illuminates the RUNNING ON GASOLINE message in the driver information center (DIC) when the vehicle is operating on gasoline. The IPC receives a class 2 message from the powertrain control module (PCM) requesting illumination.

SHIFT INDICATOR

The instrument panel cluster (IPC) illuminates the shift indicator when the powertrain control module (PCM) determines that the vehicle should be shifted to the next higher gear. The IPC receives a class 2 message from the PCM requesting illumination.

TIGHTEN FUEL CAP

The instrument panel cluster (IPC) illuminates the TIGHTEN FUEL CAP message in the driver information center (DIC) when the powertrain control module (PCM) detects a low fuel pressure condition. The IPC receives a class 2 message from the PCM requesting illumination.

VEHICLE SPEED LIMITED

The instrument panel cluster (IPC) illuminates the VEHICLE SPEED LIMITED message in the driver information center (DIC).

WAIT TO DRIVE

The instrument panel cluster (IPC) illuminates the WAIT TO DRIVE message in the driver information center (DIC) when the vehicle is not ready to drive after starting. The IPC receives a class 2 message from the powertrain control module (PCM) requesting illumination.

WATER IN FUEL

The instrument panel cluster (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.

XX% FUEL FILTER LIFE

The instrument panel cluster (IPC) receives a class 2 message from the engine control module (ECM) indicating the remaining fuel filter life percent. Once the filter is changed, the fuel filter reset procedure must be performed in order to reset the fuel filter life monitor back to 100 percent.
