• Diagnosing Intermittent Issues: VCDS can log data over time, helping to identify intermittent sensor failures that might not be apparent during a static test.
• Verifying Repairs: After replacing a sensor or repairing the ABS system, VCDS can be used to confirm that all sensors are functioning correctly and that the ABS is operating as intended.

2. How VCDS Reads Individual Wheel Speed Sensor Data

2.1. Connecting VCDS to the Vehicle

The first step is to connect the VCDS interface to the vehicle’s OBD-II port. This port is typically located under the dashboard on the driver’s side.

2.2. Accessing the ABS Module

Once connected, launch the VCDS software on your computer and select the “Select Control Module” option. From the list, choose “03 – ABS Brakes.”

2.3. Viewing Live Data

Within the ABS module, select “Measuring Blocks” or “Advanced Measuring Values.” This will allow you to view real-time data from the ABS system, including the speed of each wheel.

2.4. Interpreting the Data

The wheel speed data is typically displayed in kilometers per hour (km/h) or miles per hour (mph). Compare the readings from each wheel while driving or rotating the wheels manually to identify any discrepancies.

3. Common ABS Problems Detectable with VCDS

3.1. Sensor Failure

One of the most common ABS problems is a faulty wheel speed sensor. VCDS can quickly identify a sensor that is not providing a signal or is providing an inaccurate reading.
