Indicators
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.
CHANGE FUEL FILTER
The instrument panel cluster (IPC) illuminates the CHANGE FUEL FILTER messages in the driver information center (DIC) when the engine control module (ECM) determines that the fuel filter should be changed. The IPC receives a serial data message from the ECM requesting illumination.
CLEAN EXHAUST FILTER
The instrument panel cluster (IPC) illuminates the CLEAN EXHAUST FILTER message when the diesel particulate filter (DPF) needs regeneration. The IPC receives a serial data message from the ECM requesting illumination.
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 serial data 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 serial data message from the engine control module (ECM) indicating fuel level percent.
ICE POSSIBLE DRIVE WITH CARE
The instrument panel cluster (IPC) illuminates the ICE POSSIBLE DRIVE WITH CARE message in the DIC when the outside air temperature drops below 4°C (39°F). The IPC receives temperature information from the outside air temperature sensor.
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.
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. Programming and Relearning
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.
SHIFT INDICATOR
The instrument panel cluster (IPC) illuminates the shift indicator when the engine control module (ECM) determines that the vehicle should be shifted to the next higher gear. The IPC receives a serial data message from the ECM requesting illumination.
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).
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.
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).
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.
