tem, the vehicle must be secured against rolling away.

You must follow the specifications and instructions of

the vehicle manufacturer unconditionally.

Introduction

2 Introduction

2.1 CAN-Viewer

introduced jointly with Intel to reduce cable harnesses

and thereby weight.

By means of the CAN-Viewer, CAN messages from

any CAN bus can be easily read out, decoded in plain

text, and saved. This is accomplished without compli-

cated measuring technology and time.

Instead of using an electrical circuit for each transmit-

ted signal, the "bus" is based on a communication plat-

form which regulates the relaying of messages be-

tween several devices.

Main field of application for the CAN-Viewer is tracing

the flow of messages from EBS CAN bus to trailer inter-

face.

In a practical context, the process may be imagined as

follows:

While the rear light was actuated by means of guiding

a current to the rear light, the bus system only relays a

message: "Light switch to rear light: Switch on!"

The ability to display the communication between

tractor vehicle and trailer permits checking the data

exchange function, which is part of the duty of care

required for acceptance of the vehicle.

2.2 CAN bus

Translating all control signals into messages requires a

"greater intelligence" of the connected devices, at the

same time this implies that many devices can ex-

change information, virtually at same time, using a very

limited number of cable connections. For systems such

as EBS it is also possible to exchange much more com-

plex information e. g. on current pad wear or on individ-

ual wheel speeds in the case of ABS.

Controller Area Network (CAN) bus

The CAN bus is an asynchronous (time-shifted), serial

bus system, originally developed by Bosch to connect

electronic control devices in motor vehicles and was
