VEHICLE OVERSPEED

Vehicle's speed is equal or has exceeded the preselected value.

Engine Coolant Temperature Gauge

The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the engine control module (ECM). The IPC receives a GMLAN message from the ECM indicating the engine coolant temperature. The engine coolant temperature gauge defaults to 60°C (cold) or below if:

    • The ECM detects a malfunction in the engine coolant temperature sensor circuit.
    • The IPC detects a loss of GMLAN communications with the ECM.
    • The BCM detects a loss of GMLAN communications with the ECM.

Fuel Gauge

The IPC displays the fuel level as determined by the ECM. The IPC receives a GMLAN message from the ECM indicating the fuel level percent. The fuel gauge defaults to empty if:

    • The ECM detects a malfunction in the fuel level sensor circuit.
    • The IPC detects a loss of GMLAN communications with the ECM

When the fuel level is less than a pre-determined value, the low fuel or very low fuel indicators illuminate on the centre multi-function display (MFD).

Odometer

The IPC contains an odometer and trip odometer A or B. Momentarily press the TRIP button on the steering wheel in order to toggle between the odometer and the trip odometer. Press the ENTER button while the trip odometer is displayed to reset the trip odometer. The IPC calculates the distance travelled based on the GMLAN vehicle speed information from the ECM. The odometer will display 'error' if an internal IPC memory failure is detected.

PRNDL Display

The IPC displays the selected gear position as determined by the transmission control module (TCM). The IPC receives a GMLAN message from the TCM indicating the gear position. The PRNDL display blanks if:

    • The TCM detects a malfunction in the transmission range switch circuit.
    • The IPC detects a loss of GMLAN communications with the TCM.
    • The vehicle has a manual transmission.

Speedometer

The IPC displays the vehicle speed as determined by the ECM. The IPC calculates the kilometres based on the GMLAN vehicle speed information from the ECM. The speedometer defaults to 0 km/h if the IPC detects a loss of GMLAN communications with both the ECM.

Tachometer

The IPC displays the engine speed as determined by the ECM. The IPC receives a GMLAN message from the ECM indicating the engine speed. The tachometer will default to 0 RPM if:

    • The ECM detects a malfunction in the engine speed sensor circuit.
    • The IPC detects a loss of GMLAN communications with the ECM.

LOW FUEL

The driver information centre (DIC) displays FUEL LEVEL LOW when the IPC determines that the fuel level is less than 10 litres. The IPC receives a GMLAN message indicating the fuel level from the ECM.

LOW OIL LEVEL

The DIC displays CHECK OIL when the ECM detects a low engine oil level condition from the engine oil level sensor/switch. The IPC receives a GMLAN message indicating a low engine oil level condition.

When the Low Engine Oil Level indicator displays in the IPC or DIC due to a low engine oil level condition, make sure that the ignition is turned OFF before adding or changing the oil in the vehicle. Failure to do so may result in the Low Engine Oil Level indicator or message staying on after the engine attains the correct oil level.

LOW OIL PRESSURE

The driver information center (DIC) displays OIL PRESSURE LOW STOP ENGINE when the engine control module (ECM) detects low engine oil pressure condition from the engine oil pressure (EOP) sensor/switch. The instrument panel cluster (IPC) receives a GMLAN message requesting display of the indicator from the ECM.
