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 .
Engine Coolant Temperature
The outside left bar graph () registers coolant
temperature . One segment of the bar graph will
be displayed if the engine is cold . The number of
segments displayed will increase as the engine warms
up . With the engine at normal operating temperature,
up to fifteen segments will be displayed . The normal
working range is indicated by the green area of the
adjacent range display .
Should the coolant temperature exceed a
predetermined level, the coolant temperature bar
graph will flash . The critical alarm will sound and the
legend “STOP” will flash in the central display for 30
seconds before automatic engine shut down occurs .
Stop the engine immediately and investigate the
cause .
NOTE: The bar graph indicates engine coolant
temperature only. It is not an indication of coolant
level. The engine coolant must be checked daily.
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 before automatic engine shut
down occurs .
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.
