DIC Warning Messages






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.

CHANGE ENGINE OIL

The instrument panel cluster (IPC) illuminates the CHANGE ENGINE OIL 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 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 class 2 message from the powertrain control module (PCM) 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 class 2 message from the body control module (BCM) 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. Refer to CELL LINK.

SERVICE TIRES SOON (mideast export)

The instrument panel cluster (IPC) illuminates the SERVICE TIRE SOON message when the vehicle communication interface module (VCIM) determines that the tires have to be changed. The IPC receives a class 2 message from the VCIM.

SERVICE VEHICLE SOON (mideast export)

The instrument panel cluster (IPC) illuminates the SERVICE VEHICLE SOON message when the vehicle communication interface module (VCIM) has to be replaced. The IPC receives a class 2 message from the VCIM.

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.

TIRE SERVICE REQUIRED (mideast export)

The instrument panel cluster (IPC) illuminates the Tire Service Required message one month after the Service Tires Soon message is displayed. The powertrain control module (PCM) receives a class 2 message from the IPC limiting the vehicle speed to 64.4 km/h (40 mph).

VEHICLE SPEED LIMITED

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