DIC Warning Messages









CHANGE ENGINE OIL SOON

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

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 serial data message from the engine control module (ECM) indicating fuel level percent.

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 serial data message from the HVAC control module indicating the outside air temperature.

OIL PRESSURE LOW

The instrument panel cluster (IPC) illuminates the OIL PRESSURE LOW message in the driver information center (DIC) when the engine control module (ECM) detects a low oil pressure condition with the signal circuit low. The IPC receives a serial data message from the ECM requesting illumination.

OIL STARVATION MODE ACTIVE

The instrument panel cluster (IPC) illuminates the OIL STARVATION MODE ACTIVE message in the driver information center (DIC) when the engine control module (ECM) detects a low engine oil level condition. The IPC receives a serial data message from the ECM requesting illumination.

PROGRAM CLUSTER

The instrument panel cluster (IPC) illuminates the PROGRAM CLUSTER message in the driver information center (DIC) when a new installed IPC needs to be programmed with the correct calibration files. Refer to Instrument Cluster Programming and Setup for setup and programming.

SPEED LIMITED TO XXX

The instrument panel cluster (IPC) illuminates the SPEED LIMITED TO XXX in the driver information (DIC). The limited speed value is determined by the engine control module (ECM).

VEHICLE OVERSPEED

The instrument panel cluster (IPC) illuminates the VEHICLE OVERSPEED indicator when the IPC detects that the vehicle speed is more than 120 km/h (75 mph) (mideast export).

SERVICE VEHICLE SOON

The driver information center (DIC) illuminates the SERVICE VEHICLE SOON indicator when the engine control module (ECM) detects certain malfunctions that are not related to the emissions system. The DIC receives a serial data message requesting warning message illumination from the ECM.

TIGHTEN GAS CAP

The instrument panel cluster (IPC) illuminates the TIGHTEN GAS CAP message in the driver information center (DIC) when the engine control module (ECM) detects a low fuel pressure condition. The IPC receives a serial data message from the ECM requesting illumination.
