The
Š
KODA FABIA features a new and decentralised system
for the vehicle electrics.
The vehicle electrical system control unit plays a central role
within this system.
It combines a wide range of new functions such as check and
monitoring functions as well as relay functions.
The Self-Study Programme informs you of the new
components and the design and operation of the electrical
system of the
Š
KODA FABIA.

Decentralised Electrical System
Description/Benefits
The electrical system is a decentralised
design.
The central electrics is split up into separate
connector stations, relay boxes and fuse
holders.
–
These subunits are arranged decentrally, in
other words they are each located close to the
elements and functional units of which they
form a part.
The functions of the “vehicle” complete
system are split over several specialised
control units.
–
The control units communicate with each
other over CAN-BUS data lines.
Benefits:
–
As a result of the short wiring looms, it is
easier to locate and assign the cable
connections.
The short cable runs offer a considerable
reduction in weight.
Test points can be more easily assigned.
The components of the vehicle electrical
system are largely protected against
moisture.
The decentralised electrical system is
easier to service.
