(Go to our website www.ross-tech.com to download the latest version of VAG-COM. Click on: "Download VAG-COM Software".) Connect the Serial or USB end of Interface to the Serial or USB port on your PC. If your PC is further from the vehicle than 6 feet, connect a Serial Extension Cable between the PC and the Interface (USB is not extendable). G H If you are using a Serial Interface, you can skip to page 4 of this manual. If you are a USB Interface, this message should pop up. Click on the Found New Hardware message and the Found New Hardware Wizard should start up. Select "Install from a list or specific location (Advanced)" then click [Next >] G H This dialog should appear. Select "Search for the best driver in these locations" Check "Include this location in the search:" 2 Getting Started cont. Use the [Browse] button to find the VAG-COM folder (Usually C:\Program Files\VAG-COM\, unless you chose a different folder when you installed the software) Click [OK] G H Click [Next >] and this dialog should appear, warning you that we haven't paid Microsoft a pound of flesh to certify the driver. You're going to have to click the [Continue Anyway] button..:-) When the dialog to the right appears, Click [Finish] : G Note: If, for some reason, you installed your HEX-USB or TWIN-USB without following the above instructions, and VAG-COM does not work correctly, go into your PC's Device Manager while the HEX-USB or TWIN-USB is connected. Find the "VAG-COM Compatible USB Interface" and delete it. Then, unplug the HEX-USB or TWIN-USB from your PC, wait 5 seconds and plug it back in. Proceed with the installation starting on Page 2. 3 Getting Started cont. Connect the car end of your Interface to your vehicle's Diagnostic Port. G H If your vehicle has a 2x2 port (some pre-1996 vehicles), then use a 2x2 Adapter between the Interface and the ports in the car. Start the VAG-COM program on your PC through either the Start Menu or the icon on your Desktop. G 4 Getting Started cont. Turn the vehicle's ignition switch to the ON position. Make sure the key is turned far enough that the dash lights are fully illuminated. The engine may either be running or stopped. From the Main Screen in VAG-COM (shown on Page 6 of this Manual) click the [Options] button to go into the Options screen (shown on Page 31 of this Manual). H Select the correct port for your PC's Serial Port (typically COM1 or COM2) or USB Port (USB) and click the [Test] button. Ensure that VAG-COM finds your interface. You should see a message like this. · · If the Adapter Status is not "Found!", check the connections at the car and PC. Make sure both are plugged in securely. If K1 or K2 status is not "OK", you may have a short or an open circuit in the car's diagnostic port (most likely caused by the Aftermarket Radio Problem, as shown in the FAQ in Appendix B of this manual). Once you have tested successfully, click [OK] and click [Save] to apply this configuration, you will be returned to the Main Screen. Click on [Select Control Modules] to view the Select Control Module Screen (as shown on page 7 of this manual). Select one of your car's Control Modules such as Engine After VAG-COM has connected, click on [Fault Codes] to check for Fault Codes (DTC's). Repeat the process for each of your car's Control Modules. If you encounter problems, see the FAQ in Appendix B of this Manual first. If you still have problems, feel free to contact us with full details about your PC and vehicle, preferably while you are in front of both. Note: Your car will not have all the Control Modules listed in VAG-COM, only the ones on the Applications Page for your car. See our Website for more info: www.Ross-Tech.com/vag-com/cars/applications/ 5 VAG-COM Main Screen This screen appears when you start VAG-COM by clicking the shortcut on your Desktop or by selecting VAG-COM from the Start Menu. On this screen, you have 7 buttons that you can click with your mouse: [Select] [Auto-Scan] [Control Module Finder] [OBD-II] [Options] [About] [Exit] (This closes the VAG-COM program) See our Website for an Interactive Online version of this manual: http://www.ross-tech.com/vag-com/tour/ 6 VAG-COM Select Module Screen The various computers in the car are called "Control Modules". On this screen, you select which Control Module you want to "talk" to. Click on the button for "01 - Engine" in order to connect to the engine controller. Note: No single car has all Modules! Newer cars have more, older cars have fewer. Each tab contains groups of modules VAG-COM has buttons for all control module addresses currently supported by the VAS-5051 and VAS-5052 factory diagnostic tools. H Due to the Airbag Issue in Appendix A, if you select [15 ­Airbags] you will get this warning Module Tabs Selecting the Tab for Common, Drivetrain, Chassis, Comfort/Conv., Electronics 1, or Electronics 2 will show you different lists of module buttons. Direct Entry You can also enter any address manually. Simply put in the address and click [Go!] To return to the Main Screen, click [Go Back] Note: Your car will not have all the Control Modules listed in VAG-COM, only the ones on the Applications Page for your car. See our Website for more info: www.Ross-Tech.com/vag-com/cars/applications/ 7 VAG-COM Open Controller Function Screen This screen will appear when VAG-COM is attempting to establish communications with any of the Control Modules shown on the Select Control Modules Screen. Comm Status = Shows the status of the current communications session. It is normal for VAG-COM to take one or more tries to connect. Once communications have been established: · · · · · IC= Shows the number of times the session has been initialized. If IC increases beyond 1, communications are less than 100% reliable. TE= is counters for transmitter errors within individual packets and can indicate unreliable communication. RE= is counters for receive errors within individual packets and can indicate unreliable communication. Protocol indicates whether the controller speaks KWP-1281 or KWP-2089. (See the Function Chart in Appendix E in this manual for more information). A rotating cursor shows that communication is active. 8 Open Controller cont. Controller Info Once the communications session has been established, all of the Control Module's "Identification" data is presented here. · · · · VAG Number is the VW/Audi part number for this controller. This is often the same number as listed on the sticker on the controller itself. Component contains more identification information about the controller and may contain a version number for the controller's internal firmware. Soft. Coding is the Software Coding that determines various options for the controller. Shop # identifies the WorkShopCode stored in the scan-tool that last Recoded this Control Module. Note: Some older Control Modules are not "codeable" and you may see a Bosch part number or other information in these fields. See the Options screen for information on how VAG-COM deals with WSC. The Extra fields can show VIN and Immobilizer information or slave controller part numbers in some vehicles. This text is displayed in VAG-COM in the same manner it is presented by the controller, and may be in German in some controllers. · Basic Functions This grouping of "Safe" functions are used to read data from the Control Module. Grayed out buttons are functions that have not yet been implemented or are not applicable for this specific controller. Each of these functions is detailed on the following pages. Advanced Functions These functions are capable of making various "programming" changes to the Control Module. You should refer to the Factory Repair Manual for your particular car (or to other documented procedures) before "playing" with these functions. It is completely possible to render your vehicle inoperable or damage components if you make changes in this section without the correct information and training. Each of these functions is detailed on the following pages. Use [Close Controller, Go Back - 06] to properly close the communications session and return to the Select Control Module screen. 9 VAG-COM Fault Code Screen On this screen, VAG-COM shows you any DTC's ("Diagnostic Trouble Codes" or Fault Codes). VAG-COM shows the DTC numbers and also decodes each DTC into meaningful text. G [Print Codes] will print a Fault Code Report. If your PC is not connected to a printer when this button is pressed, be sure to use Windows to set the printer to "Work Off-Line" first! Later, when you connect the PC to a printer, un-check "Work Off-Line" to print the report. [Copy Codes] will copy your fault codes to Windows Clipboard. Once you have pressed the Copy Codes button, you may paste the results into the application of your choice, such as MS Word or Notepad. H [Freeze Frame] adds Freeze Frame data for Fault Codes on control modules using the KWP-2000 protocols. Note: Not all control modules fully support this; very few cars can currently handle freezeframe data using the VAG proprietary protocols. Self-explanatory messages will appear in place of data when this function is not supported. [Clear Codes - 05] will erase the DTC's from the Control Module's memory. Be aware, this is does not fix the problem that caused the fault! DTC's should only be erased after correcting the condition(s) that caused them in the first place. Note: There is no way to erase individual DTC's while leaving others alone. This is not a limitation in VAG-COM it's just the way the VAG protocols work. [Go Back] takes you back to the main Control Module screen where you can select other functions. 10 VAG-COM Measuring Blocks (VAG 1551/1552 function 08) On this screen, you can read all sorts of data from the Control Module in real-time. Use [Up] and [Dn] to scroll through the available groups (000 - 255 on most Control Modules). Don't become discouraged when you find some that say "ERROR: Group xxx Not Available" or if you find some groups where the fields are all blank. Most 1996 and newer ECU's have Groups in the 200 range, but there are often "gaps" in the numbers. You can also type a Group number into the Group box and click [Go!] You can also [Log] the data from the measuring blocks. For more information see page 13 ­ Data Logging. [Switch to Basic Settings] can be used to go to Basic Settings for the Group that is currently being displayed. This should be done only under guidance from the Service Manual or when following some other doc ...
