Coding the Cruise Control with Ross-Tech VCDS

Now for the crucial part: coding with your Ross-Tech VCDS. This step tells the car’s computer that the new hardware is present.

1. Connect the VCDS cable: Plug the cable into your laptop and the car’s OBD-II port.
2. Open VCDS software: Launch the software and select the correct vehicle model.
3. Navigate to the steering wheel control module: Within the software, find the control module responsible for the steering wheel.
4. Activate cruise control: Within the module’s coding, you’ll find an option to activate cruise control. The exact coding will vary depending on your Caddy’s specific configuration.
5. Save the coding: Once the changes are made, be sure to save the new coding to the module.

Troubleshooting Common Cruise Control Installation Issues

Sometimes, even with careful installation, issues can arise. Here are some common problems and solutions:

• Cruise control not engaging: Double-check all connections and ensure the correct coding was applied.
• Erratic cruise control behavior: This could indicate a faulty stalk or wiring harness.
• VCDS not recognizing the steering wheel module: Ensure the cable is properly connected and the correct drivers are installed on your laptop.

“Many DIYers get tripped up by the coding stage. Don’t be afraid to seek expert help if needed,” says John Smith, ASE Certified Master Technician.
