When the driver information center (DIC) powers up it will display CORVETTE BY CHEVROLET for 3 seconds. Then the DIC will return to display status it had before the no power condition.
The DIC can also display several warning messages. These warning messages make the driver aware of a particular problem with the vehicle. These messages are displayed along with the items below. For a list of the warning DIC messages refer to Indicator/Warning Message Description and Operation .
There are 6 buttons on the DIC switch:
- Fuel
- Gages
- Trip
- Options
- E/M
- Reset
1. Fuel
By pressing the Fuel button on the DIC, the following information will be displayed:
Average Fuel Economy (AFE)
AFE 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 |
The IPC receives fuel level information from the PCM via class 2. You can reset the AFE mode by pressing the Reset button on the DIC. The value of this mode is retained during ignition OFF.
Instantaneous Fuel Economy (IFE)
Instantaneous fuel economy is calculated as the ratio between the following values:
| • | IFE=Distance/Fuel |
| • | Distance=The accumulated distance since last update |
| • | Fuel=The accumulated fuel delivered since last update |
The IPC receives fuel level information from the PCM via class 2. You cannot reset the IFE mode. The value of this mode is retained during ignition OFF.
Fuel Range
The IPC calculates and displays the total amount of fuel used since the last reset operation.
The IPC receives fuel level information from the PCM via class 2. You cannot reset the Fuel Used mode. The value of this mode is retained during ignition OFF.
Parameter | Update Range | Range | Reset Value | Units |
|---|---|---|---|---|
Average Fuel Economy | 2 seconds | 0.0-99.9 | 0.0 | MPG or L/100 KM |
Instant Fuel Economy | 1 second | 0-99 | N/A | MPG or L/100 KM |
Fuel Range | 2 seconds | 0.0-999 | 0.0 | mi/km |
2. Gages
By pressing the GAGES button on the DIC, the following information will be displayed:
Oil Pressure
The IPC receives a class 2 message from the PCM for oil pressure data. The gage on the IPC will also display this information.
Oil Temp
The IPC monitors the signal circuit of the engine oil temperature sensor to determine the engine oil temperature.
Coolant Temp
The IPC receives a class 2 message from the PCM for coolant temperature data. The gage on the IPC will also display this information.
Trans Fluid
The IPC receives a class 2 message from the PCM for transmission fluid data.
Battery Volts
The IPC monitors the voltage at the battery voltage circuit. The gage on the IPC will also display this information.
Front
The IPC receives a class 2 message from the tire pressure monitoring (TPM) system for front tire pressure data.
Rear
The IPC receives a class 2 message from the tire pressure monitoring (TPM) system for rear tire pressure data.
Parameter | Update Range | Range | Reset Value | Units |
|---|---|---|---|---|
Oil Pressure | 2 seconds | 0-199 | 0 | KPA or PSI |
Oil Temp | 2 seconds | 0-199 | 0 | °C or °F |
Coolant Temp | 2 seconds | 0-300 | 0 | °C or °F |
Trans Fluid | 2 seconds | 0-199 | 0 | °C or °F |
Battery Volts | 2 seconds | 0-29 | 0 | V |
Front | 2 seconds | 0-99 | 0 | KPA or PSI |
Rear | 2 seconds | 0-99 | 0 | KPA or PSI |
3. Trip
By pressing the Trip button on the DIC, the following information will be displayed:
Odometer
The IPC determines vehicle odometer mileage based on Vehicle Speed Sensor (VSS) data from the PCM. The IPC permanently stores this information in memory and displays the calculated amount on the IPC. The IPC also sends this information on the serial data line to other systems requesting this information.
Trip A
The Trip A displays accumulated mileage/km to tenths of a mile/km since the last reset occurred. The Trip A odometer may be reset by pressing the RESET button on the DIC. If after the trip odometer is reset, the RESET is again pressed for at least 3 seconds, the trip odometer will display the odometer readings since the last ignition cycle. If the trip odometer is not reset, the trip odometer will roll over at 999.9 km (mi).
Trip B
The Trip B odometer functions are the same as Trip A odometer. Performing any reset functions on Trip A will not reset Trip B.
Elap. Time
The Elapsed Time feature is available for display on the IPC. When the elapsed time is displayed on the IPC, starting the timer is accomplished by pressing the RESET button on the DIC for less than 3 seconds. The IPC is able to display elapsed time in hours, minutes, and seconds. To reset the timer press and hold the RESET button on the DIC for at least 3 seconds.
Average Speed
Average speed is calculated as the ratio between the following values:
| • | Average Speed=Distance/Ignition On |
| • | Distance=Accumulated distance since last reset |
| • | Ignition On=Accumulated ignition on time since last reset |
Ignition on time is measured from the time that the ignition is turned ON to the time when the ignition is turned OFF.
You can reset the Average Speed mode by pressing the Reset button. The value of this mode is retained during ignition OFF.
Oil Life Remaining
Oil life left % is based on the information the IPC receives via class 2 from the PCM. The DIC displays the current % of the GM Oil Life System. When the oil needs changing the change engine oil indicator in the message center turns on. When the engine oil is changed the changed engine oil indicator needs to be cleared out of the message center and the oil life left needs to be reset. While in this mode press and hold the Reset button until 100% is displayed.
Off
This will turn off the DIC.
