                Online Demo / Manual - Auto Scan Screen

This function scans each controller in the vehicle to retrieve controller information -- VAG number, Component number, Soft. Coding, WSC, and Fault codes.

First, you must Select Chassis Type:
There are dozens of different control modules that exist across the entire range of VW/Audi vehicles. No one car has all Modules!  Newer cars have more, older cars have fewer. Because of this, you must select a Chassis Type that contains only those modules that are plausible for a given chassis.
If you don't know your chassis type, see our Vehicle Application Charts.

If you select Auto Detect (CAN Only) as the Chassis Type on newer cars which have a fully CAN-based diagnostic system, VAG-COM can automatically determine which modules are installed in a particular car and perform an Auto-Scan of exactly those modules. This can make the Auto-Scan considerably faster.

There is a file in the VAG-COM directory called AUTOSCAN.TXT, which contains all of the vehicle profiles. It can be edited by simply clicking on the hyperlink above the Chassis Type selection. This will open the file in your default Text editor (like Notepad) to create a custom profile for your vehicle. To help you figure out which controllers are in your car, you can run the Control Module Finder.

The Display Freeze Frame Data checkbox 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 freeze-frame data using the VAG proprietary protocols.

[Start]
This begins the Auto-Scan. Beware; this process can take several minutes.

While the scan is running, VAG-COM will cycle through the Open Controller and Fault Code screens for each controller before returning to the Auto-Scan screen. On newer control modules which have different Hardware and Software part numbers, Auto-Scan includes the Hardware Part Number as shown in the screenshots..

Double-clicking on any of the Control Modules highlighted in RED will open the Fault Codes screen for that controller and allow you to clear the codes.

[Stop]
This stops the Auto-Scan.

[Gateway Installation List]
Only available only on Gateways in cars using a direct CAN connection for diagnostics. This very fast function takes about 3 seconds to query the car's Gateway to find out what modules are installed in the car and what their status is.   Any modules having fault codes should show a "Malfunction".    Modules are directly accessible from this screen by double clicking on the appropriate line.   The following screen-shot is from an Audi Q7:


[Clear All DTC's]
This function is only available when using a HEX Interface and is implemented in two ways.   On pre-CAN vehicles, VAG-COM will access each control module and clear DTCs from each one individually.   On vehicles using CAN for diagnostics, VAG-COM performs this function without accessing all the control modules individually. If you are not using a HEX Interface then you'll need to go into each module that has faults to clear them individually.

Automatic VIN retrieval in Auto-Scan from all Immo-3 (and newer) cars.   VIN should be retrieved automatically from all cars which "know" their VIN.

Results:

The output from a 2007 VW Passat 3.6 4-motion looks like this:

[Copy]
If you close the Auto-Scan dialog, any data in its output box will be lost. If you would like to keep a record, click the [Copy] button first, then you can then paste the results into the application of your choice, such as MS Word or Notepad.

[Print]
This function sends the results to your printer.

[Save]
This saves your results to a file in your VAG-COM\Logs directory.

[Clear]
This erases your results. This does NOT erase the fault codes from any of the controllers. You'll need to go into each controller to Clear Codes.

To return to the Main Screen, click [Close]


Shareware Limitation(s):  The unregistered version will scan a very limited number of control modules and then stop.
