ICU2M
A keypad located on the auxiliary dash panel controls
the driver message center. See
Fig. 4.8. The 10-key
keypad is used to:
•
call up information on mobile screens;
•
navigate from screen to screen;
•
set up the display;
•
record significant data.
The odometer is a seven-digit display with one deci-
mal point after the sixth digit, allowing it to display
tenths of miles (or kilometers). When first installed,
the odometer starts at 0.0 miles (or kilometers).
When replaced, the odometer starts again from 0.0.
Alert Screens
Alert screens can appear at any time, even when the
vehicle is moving. They override the regular screen
display. They are warnings, cautions, or other mes-
sages that require the driver’s attention, but not all of
them are critical to the operation of the vehicle. The
word Warning or Alert sometimes flashes on the
display screen above the alert text. More important
messages take priority over less important mes-
sages.
NOTE: If there is more than one alert message
to display, press any button to scroll to the next
message, and so on until all the messages have
been viewed.
Parking Brake On
This warning message and an audible warning come
on whenever the parking brake is applied and the
vehicle is moving faster than 2 mph (3 km/h). The
screen and audible warning go away only when the
parking brake is released, or speed is reduced below
2 mph (3 km/h).
Low Oil Pressure
NOTE: All alert screens follow Low Oil Pressure
alert format.
This warning message and an audible warning come
on whenever the oil pressure falls below the mini-
mum oil pressure, whether the vehicle is idling or in
motion. See
Fig. 4.18. To dismiss the message,
press any button on the keypad.
If low oil pressure is detected during the ignition se-
quence, it displays as an active fault and the alert
screen does not appear. After 30 seconds, this mes-
sage displays again.
Low Coolant Level
This warning message and audible warning activate
whenever the coolant level falls below a preset point.
High Coolant Temp
This message and an audible warning come on
whenever the engine coolant temperature exceeds
the maximum allowable temperature.
If high coolant temperature is detected during the
ignition sequence, it displays as an active fault and
