How to Reset the Trouble Indicator on a Jetta 2006

A code reader will save you from diagnostic fees.

Once you have completed repairs on your 2006 Volkswagen Jetta, you must clear the trouble code from the car's computer. This process may almost seem like an afterthought, as it does not take long to complete. However, if if you fail to clear the code, the "Check Engine" light will remain lit on the dashboard---even if you successfully completed the repair work. To clear the code, you can use the same On-Board Diagnostics (OBD) scanner you used to diagnose the original problem.

Things You'll Need

• OBD-II scanner

Instructions

1. Connect the OBD-II scanner to the Jetta's data terminal. Look for the terminal under the driver side dash, near the trunk release/opener.

2. Turn your car on.

3. Turn the OBD-II scanner on.

4. Press the "Clear" button.

5. Turn the scanner and car off, then disconnect the scanner.

Tips & Warnings

• Each OBD-II scanner will have its own operation process. Check your scanner's manual for its particular process.
