GF54.50-P-2007TX Fuel Consumption, Function

GF54.50-P-2007TX Fuel Consumption, Function







Fuel consumption "SINCE START" (short-distance memory), function
Average gasoline consumption since start







Fuel consumption "SINCE RESET" (long-distance memory), function
Average gasoline consumption since last reset

The display screen " Since start" or " since reset" for the travel time can be activated via the system selection button (S110s3) and scroll forward/back button (S110s1) of the multifunction steering wheel.

Depending on the adjustment (miles/kilometers) and coding of the national version of the instrument cluster (A1) the display takes place in:
^ Miles per gallon
^ Liters per 100 kilometers or
^ Kilometers per liter (only when the national version Japan is coded)

The trip computer calculates the average fuel consumption figures from the mileage traveled and the consumption signal.

The consumption signal contains information about the quantity of fuel injected per unit time.

The instrument cluster (A1) receives this data in the following way:
^ The fuel consumption signal is generated by the ME control unit (N3/10) and transmitted to the engine compartment CAN in the form of a message.
^ The mileage traveled is calculated from the four wheel speeds. The signals come from the ESP, SPS [PML] and BAS control unit (N47-5) via the engine compartment CAN.

After resetting it can take up to three kilometers/miles or two minutes until sufficient data is available in order to calculate and display the consumptions correctly. Depending on the adjustment (kilometers/miles) and coding of national version of the instrument cluster (A1) the display takes place in:
^ Liter per 100 km (ECE)
^ Miles per gallon (USA)
^ Kilometer per liter (Japan)

If different values are displayed in the display screen "since start" (short-distance memory) and in the display screen "since reset" (long-distance memory), this is normal as both displays access different data records.

The display "since start" (short-distance memory) basically responds more sensitively to the current driving situation than the display "since reset" (long-distance memory)
