Timer Parameters
Advantages:
The idle shutdown timer has several advantages. One is
that it encourages drivers to shut the engine off before
leaving the truck for an extended period of time.
The other advantages include the ability to limit
unnecessary idle time, save fuel and reduce engine
wear.
Disadvantages:
When the engine shuts down as a result of the Idle
Shutdown Timer the truck’s dash remains “hot”. To avoid
draining the batteries the ignition key must be switched
to the “off” position after the engine shuts down.
Recommendations:
✔ Caterpillar recommends that this parameter be set
in the 3 to 5 minute range for most operation.
✔ Check with the truck manufacturer as to the
availability of the optional wiring to shut the trucks
electrical system off after an Idle Shutdown event.
