BAR GRAPH DISPLAYS (LCD)
The four bar graphs each consist of twenty LCD
segments.
All bar graph sensors are continuously tested for
faults. If a fault occurs, the bar graph will flash and a
fault code will be stored.
Fuel Level
The outside left bar graph, 1, shows fuel level. Each
segment of the bar graph display represents
one-twentieth (approximately 5 percent) of the total
fuel content of the tank.
When the fuel level falls so that only two segments of
the bar graph are displayed, the bar graph will flash
continually and the non-critical alarm will sound for
one second.
Engine Oil Pressure
The inside left bar graph, 2, indicates engine oil
pressure. With normal engine oil pressure, up to
sixteen segments of the bar graph will be displayed.
This is represented by the green area of the adjacent
range display.
Should engine oil pressure fall below a designated
level, the bar graph will flash. The critical alarm will
sound, the word “STOP” will flash in the central
display for 30 seconds and the engine will
automatically shut down.
Stop the engine immediately and investigate the
cause.
NOTE: The bar graph indicates engine oil pressure
only. It is not an indication of oil level. The engine oil
level must be checked daily by means of the dipstick.
