Information for the user

Information for the user
Information stored in control
units
Description and operation
Your vehicle is fitted at the factory with a ser-
ies of electronic control units responsible for
the engine and gearbox management. In ad-
dition, the control units supervise the per-
formance of the exhaust gas system and the
airbag systems.
Therefore, while the vehicle is being driven,
these electronic control units are continuous-
ly analysing the vehicle data. In the event of
faults or deviations from the theoretical val-
ues, only this data is stored. Normally, the
warning lamps on the instrument panel light
up in the event of faults.
This data can only be read and analysed us-
ing special equipment.
The storing of the data allows specialised
workshops to detect and repair faults. Stored
data may include:
Data relating to the engine or the gearbox
●
Speed
●
358
Information for the user
Direction of travel
●
Braking force
●
Detection of seat belt
●
The vehicle control units never record conver-
sations held by passengers in the vehicle.
In vehicles equipped with an emergency call
function via the mobile phone or other appli-
ances connected in the vehicle, it is possible
to send the vehicle position. If the control unit
records an accident with airbag activation,
the system may automatically send a signal.
This will depend on the network operator.
Normally, transmission is only possible in
areas with good coverage.
Event Data Recorder
The vehicle is not fitted with an event data re-
corder.
An event data recorder temporarily stores the
vehicle information. Therefore, in the event of
an accident, it is possible to obtain detailed
information about how the accident occur-
red. For example, in vehicles with airbag sys-
tems, data relating to speed of impact, seat
belt status, seat positions and airbag activa-
tion times may be stored. The volume of data
depends on the manufacturer.
Event data recorders can only be mounted
with authorisation from the vehicle owner
and, in some countries, they are governed by
local legislation.
Reprogramming control units
On the whole, all the data required for the
component management is stored in the
control units. The programming of certain
convenience functions, such as the turn sig-
nals, individual door opening and instructions
on the display can be modified using special
equipment at the workshop. If this is the case,
the information and descriptions given in the
Instruction Manual will not match the original
functions. Therefore, SEAT recommends that
any modifications be recorded in the section
"Other workshop notes" in the Maintenance
Programme.
The technical service centre must have a re-
cord of any modification to the programming.
Reading the vehicle fault memory
There is a diagnostics connector in the vehi-
cle interior for reading the vehicle fault mem-
ory. The fault memory documents errors and
deviations from the theoretical values of the
electronic control units.
The diagnostics connector is in the driver side
footwell area, next to the lever for opening
the bonnet, below a cover.
The fault memory should only be read and
reset by a specialised workshop.
