WARNING
This vehicle may be equipped from the factory
with electrical switches intended to operate
equipment
that was installed by a truck
equipment manufacturer (TEM). Instructions,
Cautions,
and Warnings for this additional
equipment will NOT be found in this manual.
Read and understand the appropriate manual
for the specific equipment in question before
operating. Failure to observe this warning may
cause property damage, personal injury, or death.
NOTE: This vehicle may be equipped with electronic, application
specific options not described in this Operator’s Manual. Many
of these features are supplied with rocker switches that have
custom labels applied. The presence of these options as factory
installed can be verified from the Line Set Ticket included with
the vehicle. A truck equipment manufacturer (TEM), however,
may have installed some of these options after production. In
that case, they will not appear on the Line Set Ticket. If installed
by a TEM, you should receive an operating guide and/or training
for the specific functions provided.
NOTE: Familiarize yourself with all of the switches that
control chassis,
engine, and body equipment and seek
adequate training on the function of all features before
operating this vehicle.
Additional detailed information on
these optional features may be found in the CT-471 Body
Builder Manual, Electrical System Component Section, and
the Body Builder Electrical Guide, both available through the
internationaltrucks.com Web site (Body Builder option, under
Customer Support menu).
Electrical System
The Electrical System provides a means to distribute the
electrical power and provide the driver with controls and
indications of vehicle performance.
This system uses
multiplexing for connecting to major functional areas of the
truck with much less wiring. The system provides interfaces
to a majority of vehicle switches and sensors.
The system
also communicates with the standard and optional system
controllers and modules in the vehicle.
These include: the
Body Controller (BC), the Electronic Gauge Cluster (EGC),
the engine Electronic Control Module (ECM), a Transmission
Control Module (TCM), the ABS Electronic Control Unit (ECU),
panel-mounted switches, and door pods.
