BODY CONTROLLER

3200, DURASTAR, WORKSTAR MODELSAt the center of the Diamond Logic Electrical System is the Body Controller (BC). The BC 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.

Serial datalinks connected to the BC include the following:

A drivetrain J1939 datalink to communicate information between the engine, transmission, Antilock Brake

System (ABS), the BC, and the Instrument Panel (IP)

A switch datalink for communicating switch status between the rocker switch assemblies (in the IP and the

switches in the door pods) and the BC

A Body Builder datalink to interface optional input/output modules with the BC

The BC is located under the IP behind a kick plate to the left of the drivers left foot. All connections are now

located inside the cab with the exception of the power connection that passes through the dash panel to the

engine compartment. The BC provides a standard interface signals for the park brake set signal. This interface

signal is described at the end of this section. The BC receives battery power from the maxi-fuse block and

Ignition (IGN) power from the IP harness.

NOTE: Pins E3, E5, and E7 of the BC 32-way connector (1602) are the Zero Volt References (ZVR) for various

sensors on the vehicle and should NEVER have battery voltage applied to them. Doing so will permanently

damage the BC. Do not connect other Ground (GND) signals to the ZVR.

NOTE: All connectors are viewed as looking at the terminal side of the connector.

The circuit attached to pin B3 should NOT have additional connections or splices added on an air chassis.

NOTE: All outputs will handle up to a 500 milliAmpere load unless stated otherwise.

NOTE: Circuits labeled Gnd Active", 12v Active", or 5v Active are open circuit until active.

No connections or splices are allowable on any signals that are highlighted in bold italic.
