Body Control Module Gen IV:
At the center of the Diamond Logic® Electrical, 12-volt, System is the Body Controller
(BCM). The BCM is an electronic module that provides multiple analog and switched
input/output interfaces to monitor vehicle sensors and control vehicle functions through
solid state switches, relay driver outputs, and serial data communications
The BCM is located under the IP behind a kick plate to the left of the driver’s left foot.
All connections are located inside the cab except for the power connection that passes
thru the dash panel to the under-hood compartment. The BCM receives battery power
from the maxi-fuse block and Ignition (IGN) power from the IP harness.
The BCM communicates with plurality of modules over a series of differing baud rate
data links in an exchange of tens of thousands of digital messages ever second. It also
receives input from various sensors and hard wire inputs throughout the truck. The BCM
converts these inputs, in accordance with the programmed “rules,” into data to be
transmitted on the datalinks. It is also the power source for circuits that feed the
components, controlled by the multiplexed switches, inside and outside of the cab. The
primary vehicle software programming resides in the BCM
