2. Meter display
1) The LCD with four vertical dots and 37 horizontal dots is used to display the fuel gauge.
2) A fuel shortage (0.899 V or over) is judged with 8,653 sampling times for 60 seconds. If a fuel short-
age is detected 7,780 times or more (i.e., a minimum of 90% of the total), the fuel shortage alarm will
be displayed.
3) If the fuel shortage alarm is displayed when the key is turned OFF, data on the alarm will be saved in
the microcomputer. If the voltage on average for 0.2 second indicates a fuel shortage (0.899 V or
over) when the key is turned ON again, the alarm will be displayed at once.
4) The alarm displayed will be canceled if the alarm cancel voltage (0.719 V or below) is detected 649
times or more (i.e., a minimum of 90% of the total) after the sensor signal is sampled 721 times for 5
seconds.
5) When the engine starts, the sensor float sways greatly, thus resulting in input voltage dispersion.
Therefore, the sampling cycle of the sensor signal is set to 25 seconds.
6) If fuel sensor disconnection occurs, the existence of fuel is not detectable, and the fuel shortage
alarm will not turn ON.
