Current Beta   

Important Note: Beta versions contain new features and functions that have not yet been as fully tested as have Release versions. If you use a Beta, you may find bugs or problems and you are expected to report them to Ross-Tech so that we can fix them before making a new Release.  Please be sure that you have also installed the latest Release on your computer  as well so that you can revert back to using that if you encounter problems with the Beta.  

Beta 907.0  includes the following new features and improvements:

  • Adaptation for latest Control Modules using UDS/ODX/ASAM protocols.
    Because Adaptation under UDS works a bit differently than it did in the past, the screen is somewhat different too:

    Channel numbers are history.  Instead, the item to be changed is selected from a drop-down box:

    Note:  Due to variations between control modules within a single type, not every channel listed will exist in every control module of that type.   If you select a channel which doesn't exist, you'll get an "Channel N/A" instead of a Stored Value.

    Once you've selected a channel which does exist, you can enter a new value:

    When you click [Do It!], you'll be asked to confirm:

    After you confirm the action, you'll be told whether the control module accepted or rejected the New Value.

  • Advanced Measuring Values on UDS modules now has a "Group UDS Requests" option which can substantially increase the sample rate when looking at multiple values:

    Each control module will have a limit on how many requests can be grouped.   Unfortunately, there does not appear to be a way to tell in advance what that limit is.   If you try to group too many requests, it simply won't work. 

  • Added a [Save to Logfile] button to the SRI screen.
     This is useful when there are questions about or difficulties with the SRI function as it's an easy way to send us a snapshot of what's going on.   Data is saved to the Session Log.

  • New and revised expanded ODX/ASAM data set, 
    Supporting the adaptation function and additonal new control modules under UDS.

  • A fix for certain new Skoda Radios, which use Service 22 on the K-Line(!)

  • New updated CODES file. 
    Now more than 13,000 fault codes and measuring value texts.

  • New HEX Firmware Version 1.81
    With some super-secret new features we're not going to disclose right now.  ;-)  As with the previous versions 1.79 and 1.80, HEX interfaces no longer boot in "dumb" mode and are no longer compatible with 3rd party applications unless the "Boot in Intelligent Mode" feature is disabled on the Options screen.

  • New USB Drivers
    Incorporating a fix for the compatibility issue that the previous Beta drivers had with some interfaces.

  • Includes all new features first introduced in Beta 904 and 812.   Click here to see what those were.

Beta 907.1 includes the following:

  • Added WSC, Importer and Equipment Number fields to the UDS Adaptation screen.
    Based on our in-house testing we had thought this wasn't necessary but field testing has demonstrated that it is.   These fields will be enabled only when actually needed:

  • Bug Fix:  The UDS Adaptation was not scaling properly when Window Size on the Options screen was set to anything other than the default value of 10.

  • Bug Fix:  Auto-Intern "Multiscan" interfaces did not work properly on some older K-Line control modules with 907.0.

Beta 907.2 includes:

  • A number of minor bug fixes for the latest cars.

  • A Revised ODX data set which fixes a problem with some measuring values that were incorrectly being shown as "N/A" in the previous one.  

Beta 907.3 includes:

  • New Drop-Box for selecting documented Adaptation Channels.    This allows quick selection of Adaptation Channels by Function if they are documented in the Label File for a particular control module:

  • New Drop-Box for selecting documented Basic Settings Groups.    This allows quick select selection of Basic Settings Groups by Function if they are documented in the Label File for a particular control module:


Known Issues:

  • USB Driver Versioning Problem:  The USB drivers shipped with Release 805 reported an incorrect version -- much higher than it should have been.    When you install the new drivers that come with this Beta, Windows will probably complain that they are older than the ones which are already installed.   You must answer "Yes" when asked if you want to replace the files anyway.   Previous versions of VCDS will also complain that the new drivers are outdated.  This can and should be ignored.

Release Notes:

  • Works only with Intelligent Interfaces (HEX, KEY and Micro-CAN).  

  • Works on Windows 98, ME, 2000, XP, Vista and 7.   Windows 95 is not supported.

  • Default installation location is C:\Ross-Tech\VCDS-Beta\. If allowed to install to its default location, it will not overwrite or interfere with the use of Release 805.

  • For controllers using the new UDS/ODX protocol, the following functions are supported:  Control Module ID (including Advanced ID), Coding, Security Access, Fault Codes, Advanced Measuring Values, Output Tests and now Adaptation (see above).  Fault Codes, Measuring Values, Output Tests and Adaptation all require a control module-specific "data dictionary" file.    If a data dictionary file is not available for a specific control module, VCDS will show an obvious error message, in which case you should contact Support@Ross-Tech.com.   We are still working on support for additional diagnostic functions under UDS but no timetable is available yet.
