The oil level float switch is positioned in the side of the
engine.
When the engine oil level is at an acceptable level, the float
switch is closed, applying an earth to the ECU1 i/p 35 (A-3)
When the engine oil level drops below the acceptable
level, the float switch is opened, removing the earth from
the i/p.
The i/p is only checked on machine ignition on.
The oil level check should occur before other machine or
engine faults are raised.

indicating that the oil level is OK, the EMS displays the
message "ENG OIL OK" for 5 seconds.
When the EMS receives a CAN message from the ECU1
indicating that the oil level is low, the EMS displays the
message "CHK ENG OIL" for 5 seconds and the buzzer
sounds for 1.5 seconds.
