Vehicle System System Operation 36
Delayed Engine Shutdown System
Operation
The delayed engine shutdown system will shut the
engine down if no proper action is taken by the
operator. This system makes use of the engine
oil pressure switch, transmission oil temperature
switch and water (coolant) temperature sensor to
get the required truck condition.
If an engine damaging condition arises, such as too
much oil pressure drop, this system will alert the
operator by warning MIL Lamp.
If the operator ignores this warning and does not
shutdown the engine within thirty seconds, this
delayed engine shutdown system will interrupt the
fuel supply to the engine, thereby saving the engine
from the critical damage.
1. Low engine oil pressure
The warning MIL lamp will turn on when the oil
pressure drops to approximately 28KPa (4 psi) and
the delayed engine shutdown system will interrupt
the fuel supply to the engine after thirty seconds.
2. Hot engine coolant
The warning MIL lamp will turn on when the coolant
temperature reaches approximately 115℃(239℉)
and the delayed engine shutdown system will
interrupt the fuel supply to the engine after thirty
seconds.
3. Hot transmission oil
The warning MIL lamp will turn on when the
transmission oil temperature reaches approximately
125℃(257℉) and the delayed engine shutdown
system will interrupt the fuel supply to the engine
after thirty seconds.
