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 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.

ENGINE OIL LOW

The instrument panel cluster (IPC) illuminates the ENGINE OIL LOW message in the driver information center (DIC) when the engine control module (ECM) detects a low engine oil level condition. The ECM 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 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 engine control module (ECM) indicating fuel level percent.

KM/H

The instrument panel cluster (IPC) displays the km/h indicator when the cluster detects that Metric units have been requested.

MPH

The instrument panel cluster (IPC) displays the MPH indicator when the cluster detects that English units have been requested.

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 class 2 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 the IPC needs to be programmed. Refer to Instrument Cluster Programming and Setup for setup and programming.

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).

VEHICLE SPEED LIMITED

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

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 class 2 message from the ECM requesting illumination.

UPSHIFT INDICATOR

The instrument panel cluster (IPC) illuminates the upshift 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.

WATER IN FUEL SERVICE REQUIRED

The instrument panel cluster (IPC) illuminates the WATER IN FUEL message in the driver information center (DIC) when the engine control module (ECM) detects a low signal from the water in fuel sensor. The IPC receives a serial data message from the ECM requesting illumination.
