Corresponds to VAG 1551/1552 function 04
This screen is presented when a Control Module is in Basic Settings Mode.
The Control Module may try to perform various calibrations while in Basic Settings mode.
Dual ECU's: For vehicles with dual ECU's (like the Audi R8), the Basic Settings mode for both ECU's can be accessed simultaneously by addressing [31-Engine Other]
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 Settings groups.
Basic Settings for latest Control Modules using UDS/ODX/ASAM protocols.
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, a searchable list of UDS Measuring Values can be displayed simultaneously by clicking on the [Show Measuring Data] button.
On UDS control modules there is a [Clear DTCs]Show Measuring Data]button that can be used for example to clear fuel trims while watching the measuring values. Obviously don't do this until after you have saved fault codes from a module, perhaps as part of an AutoScan.
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 directory like this: Save.txt
[Switch to 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.
The [Graph] button 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 VC-Scope page.
You can begin and end a Data [Log] while in Basic Settings.
Use [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 some cars. Please refer to a Factory Repair Manual for your car before attempting to do ANY of these procedures!
