Instrumentation Control Unit

The ICU3 instrument cluster is a single unit that pro-
vides the driver with engine and vehicle information.
It is comprised of gauges, warning and indicator
lamps, an audible warning, and a liquid crystal dis-
play (LCD) screen.

IMPORTANT: Vehicles that are domiciled out-
side of the U.S. and Canada may not have
EPA07- or EPA10-compliant engines with an
emission aftertreatment system (ATS), depend-
ing upon local jurisdictional emissions guide-
lines.

Figure 3.1

shows a typical ICU3 instrument cluster

installed in EPA07- and EPA10-compliant vehicles.

Vehicles that are not EPA10-compliant do not have a
fuel/diesel exhaust fluid (DEF) gauge.

There can be up to eight gauges on the driver’s in-
strument panel (six electronic and two mechanical).
The air gauges operate mechanically.

The ICU3 also has the capability to drive up to six
independent stand-alone gauges such as those in-
stalled on the auxiliary dash panel.

Figure 3.2

shows

a typical dash panel layout.

Dash Message Center

The dash message center houses all of the standard
and optional warning and indicator lamps, as well as
the driver display screen. The display screen has a
