Average Vehicle Speed

Average vehicle speed is calculated using the equation: Average Speed = AVS Distance/AVS Time

Fuel Range

This message indicates the estimated distance that the vehicle can travel under the current fuel economy and fuel level conditions since the last battery connection to the IPC. Fuel Range is calculated using the equation: Fuel Range = Range Distance/Range Fuel Used.

The ECM sends the fuel range value to the IPC. IPC receives a serial data message with the fuel information. The fuel range value is retained during ignition OFF and can be changed between English and Metric units by accessing the DIC trip/fuel information switch. The Fuel Range display cannot be reset. LOW is displayed when fuel range is below a predetermined value.

Fuel Used

This message indicates the amount of fuel used since last reset. Fuel Used is calculated using the equation: Fuel Used = Fuel Sum.

The ECM sends the fuel used value to the IPC. The IPC receives a serial data message with the fuel information. The fuel used value is retained as long as battery power is available to the DIC. The fuel used value can be changed between English and Metric units by accessing the DIC trip/fuel information switch.

Elapsed Time

The timer records elapsed time starting from activation. When the DIC displays the timer, pressing the DIC SET/RESET switch for 1 second resets the timer. Pressing the SET/RESET button on the DIC switch for approximately 1 second starts and stops the timer. The DIC displays the timer in one of the following formats:

The DIC displays the timer in the following format: XX: XX:XX:

The first XX represents hours elapsed, the second XX represents minutes elapsed, and the third XX represents seconds elapsed. The maximum range of the timer is 99 hours, 59 minutes, and 59 seconds. After the maximum range is reached, the timer displays all zeros (00:00:00).

Battery voltage data is not determined by the DIC and is not a resettable parameter. The DIC displays (- - -) when an invalid battery data is received or when the IPC experiences a loss serial data communications.
