CURRENT FUEL CONSUMPTION
METER INSPECTION (NSS250S)
• The current fuel consumption meter has the fuel
consumption of the average and instant.
• The current fuel consumption meter displays the
calculated average fuel consumption by receiv-
ing the pulse signals of the ECM from the point
where the meter is reset.
• When ignition switch is turned OFF, the calcu-
lated value of the distance and fuel consumption
after reset should be stored in EEPROM. If the
value is not stored, [ _ _ . _ ] (under score)
(EEPROM failure) will be displayed when the
ignition switch is turned ON and the calculation
will be disabled.
Instant fuel consumption stays shown 0 km/h (0
mph)
