Fuel Distance/Mileage Module: Description and Operation
The Consumption Signal is connected to pin 31 of the Motronic control module, the signal is directional OUT only (PIN 31 - OUTPUT ONLY).The consumption signal is used for instantaneous fuel consumption data. It is calculated directly from the injection time and discharging rate of the fuel tank ventilation system.
The on-board computer uses the consumption signal for display of current and average fuel consumption values.
NOTE: This signal is simultaneously used as a load signal by the automatic transmission control module (if equipped).
