DESCRIPTION

Manual has been written as an aid in troubleshooting

problems that may occur in machine CAN bus electrical

system. Manual is arranged in order or error codes with

some additional sections following for circuits that are

not associated with a code.

REQUIREMENTS

This manual is to be used by a qualified technician with

basic knowledge of electrical systems.

Technician must have a multimeter and experience in

using the meter.

Technician must have proper tooling and repair

supplies for various connectors described throughout

this manual.

IMPORTANT: CAN bus system must be rebooted

connection has been altered. This is

accomplished by disconnecting battery with

negative cable disconnect assembly located in

battery box. Often problems are fixed by

simply rebooting.

DEFINITION

FIG. 1: CAN (Controller Area Network) is a method of

communication which allows a large amount of data to

be transferred through two which wires. A CAN network

is similar to a computer network, using a server(s)

(master module), and terminals (I/O Input / Output

interface modules) to communicate in a controlled and

standardized binary code. Use of a CAN network

allows greatly reduced amount of wiring in many

electrical circuits.

Machine chassis and system will use CAN bus for

following functions:

1. All lighting circuits;

2. Sensors;

•

Air Pressure;

•

Fuel Level;

•

Hydraulic Level;

•

Radar.

3. Engine;

4. Transmission;

5. Drive lever.

FIG. 3: Master Module

Master Module is located behind the right rear curved

panel on outside of the cabin. To access panel loosen

hand nut located in center of curved panel. Master

module accepts signals from switches and other

modules in cab, translates, and transfers those

commands via a two-wire shielded harness to I/O

(Input/Output) interface module. Master module also

accepts inputs back from I/O interface modules and

forwards those signals to proper component.

J1 Connector (1) - pins are inputs except where

designated.

J2 Connector (2) - pin  is output except where

designated.
