freightliner Run Smart ARGOSY, Driver Manual

Instrumentation Control Units
The instrumentation control unit (ICU) provides the
driver with engine and vehicle information. It is com-
prised of standard and optional gauges, an audible
warning, a driver message center, and a lightbar con-
taining warning and indicator lamps (also known as
telltales). Warning and indicator lamps illuminate in
red (danger), amber (caution), green (status advi-
sory), or blue (high-beam headlights activated).
Argosy vehicles are equipped with either an ICU4M
(
Fig. 4.1 ), ICU3 ( Fig. 4.2 ), or ICU2M ( Fig. 4.3 ).
The following headings in this chapter provide addi-
tional information and operating instructions for ICU
components:
•
"Warning and Indicator Lights"
•
"Instruments"
•
"Driver Message Center"
Ignition Sequence
When the ignition is turned on, the ICU runs a self-
check. See
Fig. 4.4 . Observing the ignition sequence
is a good way to ensure the ICU is functioning
properly.
IMPORTANT: Do not crank the engine until the
ICU gauge sweep is complete.
NOTE: Air gauges do not complete a sweep of
their dials during the ignition sequence.
When the ignition is turned on, the following actions
should occur:
•
electronic gauges complete a full sweep of
their dials
•
some warning and indicator lamps illuminate,
then are extinguished
