Audible alert sounds for any active faults
•
Active alerts are displayed on the ICUC
screen.
If the ICUC receives active fault codes, it displays
them one after the other until the ignition is turned
off. The alerts are displayed until they are
acknowledged. If there are no active faults, the ICUC
displays the home screen after the self-check
completes.
IMPORTANT: If any red or amber warning and
indicator lamps do not illuminate during the
ICUC self-check or do not go out (if not active)
after the self-check completes, take the vehicle
to an authorized Freightliner service facility as
soon as possible.
If active faults are present, take the action
outlined in "Warnings, Indicators, and
Messages" tables in this chapter, then take the
vehicle to an authorized Freightliner service
facility as soon as possible.
ICUC Screen Navigation
In the ICUC, the driver display screen is broken up
into three areas as shown in
menu at the top of the screen, a static display at the
bottom of the screen, and the central display area
(with screen indicator dashes to communicate how
many display screens are available in the current
menu category).
NOTE: To adjust the brightness of ICUC screen
go to User Settings.
The ICUC top level menu categories, shown in
Fig. 3.1, allow a driver to quickly carry out common
actions. Top level menu categories are Home, Drive
Time Systems, Vehicle Operations, Maintenance,
Infotainment, and User Settings.
The static menu display at the bottom of the screen,
shown in Fig. 3.3, displays the current vehicle speed,
transmission gear, cruise control information, a clock,
and active telltales.
ICUC Steering Wheel Switch Pods
To navigate the ICUC menus, use the 'Menu Right'
and 'Menu Left' arrows on the left-hand steering
wheel switch pod, shown in
between the top-level menus. Use the 'Menu Up' and
'Menu Down' buttons to move from screen to screen
