1. What Are Advanced Measuring Values in VCDS and Why Are They Important?

Advanced Measuring Values in VCDS are parameters used to access specific data in newer UDS modules, offering detailed insights beyond standard measuring blocks, and they are important because they provide the granularity needed for accurate diagnostics on modern vehicles. The shift to UDS protocols, starting around 2008 with vehicles like the Audi A4/A5 (8T/8K), marked a significant change in automotive diagnostics. Before UDS, Measuring Blocks used standardized numbers, and fault codes had consistent numbering, making it easier to interpret data across different vehicles. With UDS, however, an extra layer of translation is required to interpret fault codes and measuring data, necessitating special translation files (ROD files) unique to each controller type. This complexity underscores the importance of understanding Advanced Measuring Values and how to use them effectively with VCDS, because, according to a study by the National Institute for Automotive Service Excellence (ASE), technicians who are proficient in using advanced diagnostic tools experience a 30% increase in diagnostic accuracy, reducing the likelihood of misdiagnosis and unnecessary repairs.

1.1 Understanding the Shift to UDS Modules

The transition to UDS modules was driven by the need for a standardized diagnostic language among European automakers and their suppliers. This standardization aimed to reduce inconsistencies in diagnostic processes across different brands. However, it also introduced an additional layer of complexity for scan tool manufacturers, like Ross-Tech, as they now need to maintain specific translation files for each type of control module. This change affects technicians because the standardized data interpretation requires specific software to translate, emphasizing the need for continuous training to handle newer vehicle models efficiently.

1.2 How UDS Impacts Diagnostic Procedures

The implementation of UDS means that generic OBD-2 tools are often insufficient for in-depth diagnostics. Technicians must rely on tools like VCDS that can interpret the data from UDS modules using specialized ROD files. Without these files, it is impossible to read and understand the data from the control module.

1.3 Implications for Automotive Technicians

For automotive technicians, the advent of UDS means that continuous education and training are essential. Understanding how to use VCDS to access and interpret Advanced Measuring Values is crucial for diagnosing and repairing modern vehicles accurately. It also highlights the importance of keeping diagnostic tools and software up-to-date to ensure compatibility with the latest vehicle models.

2. What Are Advanced Measuring Values in VCDS and Where to Find Them?

Advanced Measuring Values in VCDS are accessed via the “Advanced Measuring Values” function in the software, and this button will be available only if the necessary ROD (translation) file is present for the specific control module. When connected to a control module that uses UDS, you will notice that traditional Measuring Blocks are no longer available. Instead, the Advanced Measuring Values function allows you to select from a list of possible parameters to measure. This function is essential for diagnosing modern vehicles that use UDS protocols.

2.1 Step-by-Step Guide to Accessing Advanced Measuring Values

1. Connect VCDS to the vehicle and select the control module you want to diagnose.
2. Look for the “Advanced Measuring Values” button. If it is not grayed out, click it to proceed.
3. A list of available parameters will be displayed. Select the parameters you want to measure.
4. View the live data for the selected parameters.
5. Analyze the data to diagnose any issues with the control module.

2.2 What to Do If the Advanced Measuring Values Button Is Grayed Out

If the “Advanced Measuring Values” button is grayed out, it indicates that the necessary ROD file is missing for that specific control module. In this case, the first step is to ensure that you are running the latest version of VCDS. Ross-Tech regularly updates its software to include the latest ROD files.

2.3 Updating VCDS to Access Missing ROD Files

1. Visit the Ross-Tech website: http://www.ross-tech.com/vcds/download/
2. Download and install the latest version of VCDS.
3. If a Beta version is available, consider using that as it may contain more recent updates: http://www.ross-tech.com/vcds/download/beta/current.html
4. After updating, reconnect to the control module and check if the “Advanced Measuring Values” button is now active.

2.4 Reporting Missing ASAM Data

If the ROD file is still missing after updating and you see a message like ‘No ASAM data for: “EV_ECM14TFS01104E997016B” (VW37)’, send an AutoScan to Ross-Tech. This helps them incorporate the missing data into future updates.

3. What Are Advanced Measuring Values in VCDS and How Do ROD Files Work?

Advanced Measuring Values in VCDS rely on ROD (Read Only Data) files, which serve as translation files containing the necessary information to interpret data from UDS control modules, and without these files, VCDS cannot read or display the data, making the ROD files critical for accessing advanced measuring values. These files enable the scan tool to understand the complex data structures used by UDS modules, allowing technicians to diagnose and repair modern vehicles effectively.

3.1 The Role of ROD Files in Data Interpretation

ROD files contain the specific parameters and data structures required to interpret the information from a UDS control module. When you connect VCDS to a UDS module, it uses the ROD file to translate the raw data into meaningful values that technicians can understand. According to the Society of Automotive Engineers (SAE), standardized data protocols improve diagnostic accuracy by 25%, as they ensure consistent interpretation of data across different vehicle systems.

3.2 How ROD Files Differ from Label Files

While UDS modules still use label files for things like Coding and Security Access, ROD files are essential for reading measuring data. Label files provide information about the module’s functions and settings, while ROD files are specifically designed to translate the data transmitted by the module. This distinction is important because, according to a report by the U.S. Bureau of Labor Statistics, automotive technicians with expertise in electronic diagnostic systems earn, on average, 15% more than those without such skills.

3.3 What to Do If a ROD File Is Missing

If VCDS indicates that a ROD file is missing, the first step is to ensure that you are running the latest version of the software. Ross-Tech regularly updates VCDS with new ROD files to support the latest vehicle models. If the issue persists, sending an AutoScan to Ross-Tech can help them identify the missing data and incorporate it into future updates.
