The VCDS (VAG-COM Diagnostic System) software allows for deep diagnostic and customization capabilities in Audi vehicles. A key feature is the “Controller Channels Map” function, generating an “Audi Vcds Map” of a vehicle’s control modules. This map provides a comprehensive overview of Measuring Blocks (measuring values) and Adaptation Channels, enabling users to understand and modify vehicle settings. This guide explains how to create and utilize these maps.
Creating an Audi VCDS Map with VCDS
Accessing the “Controller Channels Map” function within the VCDS “Applications Screen” initiates a scan of all possible Measuring Block groups and Adaptation Channels on a chosen controller. This scan creates a “map” file. For modules using UDS (Unified Diagnostic Services), a modern HEX-NET or HEX-V2 interface is necessary to map Measuring Values. Furthermore, the module’s supporting ROD (Readiness code and OBD monitor Diagnostic) file must also be present.
The HEX-NET or HEX-V2 interface is also required for creating ‘Raw Hex’ Adaptation Map files. This format allows saving and restoring a control module’s Adaptation channels to a previously saved state. Restoration is only possible from the “adphex-[whatever].csv” file format, highlighting the need to create a Raw Hex map before restoring adaptations. It’s important to note that the Restore functionality might not be compatible with older control modules utilizing the KW1281 protocol.
Initiating the Mapping Process
Users can select a specific Controller Address (e.g., 01 for Engine) and input any necessary Login or security access code. In most cases, this code is not required; however, contacting Ross-Tech for assistance is recommended if needed. Alternatively, selecting “Whole Vehicle” scans all controllers on CAN-Bus equipped vehicles. This process can be time-consuming; using a battery charger or letting the engine idle is advised.
After selecting the target controller and access method, choose between mapping “Measuring Values,” “Adaptations,” or both. Output file format options include CSV (Comma Separated Values) and PLB (Prototype Label, Blocks). The PLB format is particularly useful for creating new label files or capturing a comprehensive snapshot of all available data from an ECU (Electronic Control Unit).
Clicking “Go” starts the mapping process, automatically saving results to the “C:Ross-TechVCDSLogs” directory.
Further Resources and Conclusion
The Ross-Tech wiki provides more detailed information on creating and using Control Module Maps, enhancing the functionality and comprehensiveness of VCDS. Returning to the Applications screen is done by selecting “Done, Go Back.” Utilizing the Audi VCDS map empowers users to diagnose and customize their vehicles with greater precision, offering advanced control over various vehicle parameters. Understanding the mapping process and available resources allows for effective use of this valuable VCDS feature.
