Basic Settings Screen
Corresponds to VAG 1551/1552 function 04
This screen is presented when a Control
Module is in Basic Settings Mode.
Basic Settings Mode is very similar to
Measuring Blocks, and the contents of each display group is the
same. The difference between the functions is that the Control Module
may try to perform various calibrations while in Basic Settings mode.
For vehicles with dual
ECU's (like the Audi R8), the Basic Settings mode for both ECU's can be
accessed simultaneously by addressing
For control modules that
have a Label File with Basic Settings information, a drop-down menu is
available which allows you to select from the supported Basic Settings
functions.Below that menu is an area to
display additional info for Basic Settings. The data to be
displayed in this area comes from the Label files and it may
take some time before tips are included for most Basic
Basic Settings for latest Control
Modules using UDS/ODX/ASAM
As is the case for other functions under UDS, there are no longer any channel or group numbers.
Instead, the Basic Setting to be performed must be selected from a drop-down list:
On UDS control modules which offer "Instructions", VCDS will
automatically display them. In addition, UDS Measuring Values can be displayed simultaneously:
You should refer to the Factory Repair Manual for your
particular car (or some other documented procedure) before
"playing" with the Basic Settings function. Failure to follow the proper
procedures can result in serious damage to the vehicle.
Although you can use the
[Dn] buttons to scroll
through the available groups just like on the Measuring Blocks screen,
this is probably not a good idea since you may put the Controller into
Basic Settings for a Group that you did not intend.
You should enter a Group number
directly and click [Go!]
If you'd like to record just a snapshot in time of the current
readings in each group, click on
[Add to Log].
This will save the results to your PC, typically in your VCDS\Logs
Meas. Blocks] will
switch back to the passive (and "safe") Measuring Blocks mode, in
controllers using KW-1281. In Controllers using KWP-2000/CAN/UDS, there may be an
[ON/OFF/Next] button that allows you to initiate and exit
Basic Settings while still being able to see the values in the
measuring groups. This does not appear every time and it's
appearance and function are up to each controller in the car.
Multiple Groups are not permitted in Basic Settings. The data
presented in each Basic Settings Group varies greatly
from Control Module to Control Module and between different models and
years. Some groups are documented in the Factory Repair Manuals, but
many are not.
VCDS tries to elaborate
on the meaning of the data as
much as possible but the "Data Type"
information coming from the Control Module is not very precise. For
example: VCDS can tell that a particular field contains a
Temperature, but the data from the Controller doesn't tell us whether
this is the Coolant Temperature or the Intake Air Temperature.
To reduce the confusion, VCDS
supports Label Files and will display the name of the Label File. The
Label File name is displayed on the top left when you are in Measuring
Blocks or Basic Settings. If you click on the name of the Label File,
the file will open in Notepad or whatever program you have set to handle
*LBL files. When a
Label file for the Control Module you are looking at does not exist,
VCDS will come up with an "educated guess" for what a particular Data
Type means. The dealers' VAG-1551 and 1552 scan-tools do not provide any
elaboration; they only show what’s in the display fields! Basic
Setting will display a popup balloon when the mouse if hovered over each
value, if the Label File contains information for that field in that
controller. See the Measuring Blocks section for more information.
is used to open up VC-Scope, a plug-in for VCDS
that allows you to graph Basic Settings Information and displays
customizable virtual gauges. For more information, see the
[Done, Go Back] to return to
the Controller Info / Select Function screen.
The most common use for the Basic
Settings function is to recalibrate the Throttle Body. Another common
use for Basic Settings is to bleed the ABS Hydraulic Unit on newer cars.
Please refer to a Factory Repair Manual for your car before attempting
to do this!
