Activating Traffic Sign Recognition (TSR) on a 2017 Volkswagen Alltrack can enhance driving safety and convenience. TSR uses a forward-facing camera to detect and display speed limit and other traffic signs on the instrument cluster. While the process may seem straightforward, some users encounter challenges. This article outlines the activation procedure and addresses common issues, specifically focusing on using VCDS (Vag-Com Diagnostic System) for coding.
Activating Traffic Sign Recognition with VCDS
The following steps describe the process of activating TSR using VCDS:
Step 1: Accessing Control Modules with VCDS
- Connect your VCDS interface to the vehicle’s OBD-II port and launch the VCDS software.
- Select “Select Control Module” from the main menu.
Step 2: Configuring the Information Electrical Control Unit (5F)
- Choose Control Unit 5F (Information Electrical).
- Go to “Adaptation.”
- Adjust the following channels:
- Channel 63 (vehicle function list BAP traffic_sign_recognition_0x21): Set the value to “Active.” This enables the core TSR functionality.
- Channel 151 (vehicle menu operation-menu_display_road_sign_identification): Set the value to “Active.” This allows the TSR settings to be displayed in the vehicle’s menu.
- Channel 153 (vehicle menu operation-menu_display_road_sign_identification_over_threshold_high): Set the value to “Active.” This enables warnings when exceeding speed limits detected by TSR.
Step 3: Accessing and Coding the Front Camera Control Unit (A5)
- Select Control Unit A5 (Front/Advance Camera).
- Go to “Security Access” and enter the access code 20103. This allows modification of the control unit’s coding. This step is crucial for enabling communication with the camera module.
- Navigate to “Long Coding.”
- Byte 1, Bit 0: Activate – “01 Traffic Sign Recognition (FTE) active.” This step directly activates the TSR function within the camera’s software.
- Potential Issue: Some users report inability to change coding in module A5. Instead of individual bit selection, only model/variant selection is available. Further research might be required to find specific long coding for this particular vehicle and camera module combination. Manual code entry might be possible, but requires careful verification.
Step 4: Configuring the Dashboard Control Unit (17)
- Select Control Unit 17 (Dashboard).
- Go to “Long Coding.”
- Byte 5, Bit 2: Activate. This enables the display of traffic signs on the dashboard instrument cluster.
Step 5: Fine-tuning the Front Camera (A5) – Adaptation Channel for Speed Limit Display
- Return to Control Unit A5 (Front/Advance Camera).
- Go to “Adaptation.”
- Locate the channel related to speed limit display end value adjustment (the channel number may vary depending on the specific vehicle configuration).
- Adjust the value as needed. The default value is often “00100111,” but researching your specific vehicle model year and options might reveal a more accurate recommended value.
Troubleshooting and Further Considerations
- Coding Issues in A5: If you cannot modify the coding in Control Unit A5 as described, consult online forums specific to your vehicle model. Look for verified long coding strings for your specific camera module part number. Proceed cautiously if attempting manual code entry. Always document original coding before making any changes.
- Camera Calibration: After activating TSR, camera calibration might be necessary for optimal performance. This procedure often requires specialized equipment or dealer-level diagnostic tools.
- VCDS Version: Ensure you are using the latest version of VCDS software for accurate compatibility and access to the most up-to-date coding information. Older VCDS versions might lack the necessary data for newer vehicles.
Conclusion
Activating Vcds Traffic Sign Recognition on a 2017 Alltrack requires careful attention to detail and accurate coding. While challenges may arise, particularly with Control Unit A5, online resources and forums dedicated to VCDS and Volkswagen vehicles can offer valuable assistance. Remember to thoroughly research your specific vehicle and camera module before making any coding changes. Following these steps can significantly improve your driving experience by providing real-time traffic sign information. Always prioritize safety and consult with a qualified technician if you encounter any difficulties.
