14.2 Technical lexicon

CAN, Controller Area Network, developed by
Bosch in the early 1980s, was specially developed
for fast serial data interchange between electronic
control units in motor vehicles. With CAN, each
message to be sent is clearly identified by a mes­
sage code.
In contrast to station addressing, the message it­
self is addressed rather than the control unit. Con­
sequently, a message is essentially available to
each CAN bus station for receipt. The transfer of a
message depends solely on the decision of the
control units. It is therefore possible for a message
to be accepted by one, several or all control units
for further processing.
CR, common rail. Whereas conventional diesel
models with direct injection build up the fuel
pressure from scratch for each injection, the com­
mon-rail system builds it up regardless of the injec­
tion sequence so that it is permanently available in
the fuel line. Pressurisation and injection are two
separate processes. This technology allows injec­
tion on demand, which has a favourable effect on
fuel consumption and exhaust emissions.
EDC, Electronic Diesel Control. This system has a
positive effect on fuel consumption, economy,
emissions and noise.
Carefully read through the Operating Instructions before starting any work!
This particularly applies to the General Safety Instructions section
and the safety instructions in the various chapters.
