update can start. Once started, a software update
cannot be cancelled.
During the software update process, progress
messages will be provided. See
ICUC software update screens.
If a software update is interrupted, the system will
ask if you want to restart the process or inform you
that the vehicle cannot be driven until the update is
complete. If a software update fails, the system will
attempt to revert to the previous version. A
notification will appear when a software update has
been successfully installed.
Failure to install software updates may make data
less secure and/or mean vehicle systems are not
operating at their best.
NOTE: An estimation of installation time will be
given before the software update starts.
Installation can take several minutes. During
installation individual functions and controls will
not be available or only available to a limited
degree.

Digital Gauges and System
Monitors: ICUC
ICUC Gauges
In the ICUC there are six digital gauges and system
screens for the Diesel Particulate Filter (DPF) and
Tire Pressure Monitoring System (TPMS).
The six digital gauges under the Vehicle Operations
menu of the driver display are:
•
Engine Oil Temperature
•
Turbo Boost Pressure
•
Transmission Oil Temperature
•
Front Axle Oil Temperature
•
Rear Axle Oil Temperature
•
Application Air Pressure
In the ICUC, if a value measured by a digital gauge
exceeds the normal range, an amber caution or red
danger popup message will appear. However the bar
graph color will remain green and the bar graph
icons will remain white.
NOTE: The order of ICUC digital gauges and
therefore the screen on which they display can
be changed under Gauge Settings under
Settings.
Engine Oil Temperature Gauge
NOTICE
A sudden increase in oil temperature that is not
caused by a load increase may indicate
mechanical failure. Bring the vehicle to a safe
stop and investigate the cause to prevent further
damage. Do not operate the engine until the
cause has been determined and corrected.
During normal operation, the optional engine oil
temperature gauge, shown in
in the following temperature range:
•
200 to 260°F (93 to 126°C) for Detroit and
Cummins engines
Under heavy loads, such as when climbing steep
grades, temperatures that exceed the normal oil
temperature range for a short period are not unusual.
If the temperature returns to normal when the load
decreases, there is no problem.
