FUEL USED

The FUEL USED message is the number of gallons or liters used since the last parameter reset. The IPC calculates the fuel used parameter as follows:
Fuel Used = Fuel Sum x Scale Factor.

In order to reset, display the fuel used parameter and press the RESET (digital) or INFO RESET (analog) button for at least 1 second. The data used in order to calculate the fuel used is lost if a battery disconnect occurs. The message contains dashes if the IPC is unable to communicate with the PCM via the class 2 serial data line. This message may be suppressed by using the override option E. Refer to Vehicle Diagnostic System. The data is lost if the battery is disconnected.
