LaCrosse V8-5.3L (2008)
Gages Button (Uplevel DIC)
This button is used to access the Oil Life Remaining, Transmission Fluid Temp, Battery, Engine Hours, and Engine Boost (with supercharger) modes.
Oil Life Index (OLI) and Reset
The Engine Oil Life Remaining mode will indicate the percentage of remaining oil life before the driver is alerted to change the oil. The PCM/ECM will
transmit the class 2 message to display the CHANGE OIL SOON warning in the DIC once the remaining oil life falls below five percent. Once the oil
has been changed, the engine oil life monitor needs to be reset.
Battery Voltage
The DIC displays the current voltage as communicated by the body control module (BCM).
Tire Pressure Monitor System Reset
Allows the reset of the Tire Inflation Monitor System on ABS equipped vehicles once air pressure within the tires has been changed.
Fuel (Uplevel DIC)
This button is used to access the Average Fuel Economy (AFE), Instantaneous Fuel Economy (IFE), and the Fuel Range modes.
Average Fuel Economy (AFE)
The DIC displays the average miles per gallon or average liters per 100 km/h. Average Fuel Economy (AFE) is resettable with the Set/Reset button and
is calculated as the ratio between the following values:
*
AFE=Distance/Fuel
*
Distance=The accumulated distance since the last AFE reset
*
Fuel=The accumulated fuel consumption since the last AFE reset
Instantaneous Fuel Economy (IFE)
The DIC will display the instant fuel economy under the current driving conditions and will change as driving conditions change.
Fuel Range
The Fuel Range indicates the distance that the vehicle can travel under current fuel economy and fuel level conditions. It is calculated from cumulative
fuel usage, fuel remaining, and odometer information. Fuel Range is not a resettable parameter. If the fuel tank contains less than 2 gallons (7.6 L) the
DIC will display the low fuel message.
Ambient Air Temperature
The ambient air temperature is displayed in the driver information center (DIC) by the instrument panel cluster (IPC). The IPC displays the ambient air
temperature in Fahrenheit or Celsius. The ambient air temperature sensor is interfaced with the IPC via two discreet circuits: the ambient air temperature
sensor signal circuit and the low reference circuit. The instrument panel cluster (IPC) monitors the signal circuit of the ambient air temperature sensor.
The ambient air temperature sensor is a thermistor which varies in resistance as the ambient temperature changes. As the resistance of the ambient air
temperature sensor increases, the IPC senses a larger voltage drop across the sensor, indicating a lower temperature. As the resistance of the ambient air
temperature sensor decreases, the IPC senses a smaller voltage drop across the sensor, indicating a higher temperature. The DIC displays "SC" when the
ambient air temperature is shorted to ground and displays "OC" when an open circuit exists. When the ambient air temperature is at or below 37°F (3°C),
the "ICE" warning message is intermittently displayed in the DIC for approximately 2 minutes.
Compass
The instrument panel cluster (IPC) displays the vehicle compass heading in the driver information center (DIC). The internal fault detection of the
electronic compass module is handled by the instrument panel cluster (IPC). The compass information is sent to the IPC via 2 discreet inputs from the
external electronic compass module. The DIC displays 2 dashes (- -) when the IPC looses connection with the electronic compass module. For compass
calibrations and zones refer to: Electronic Compass Calibration (See: Instrument Panel, Gauges and Warning Indicators/Compass/Adjustments).
