How do you clear codes on 02 rendezvous?

To clear codes on a 2002 Buick Rendezvous, you'll need an OBD-II scanner. Connect the scanner to the vehicle's diagnostic port, typically located under the dashboard near the driver's side. After reading the codes, select the option to clear or erase the codes. Once completed, disconnect the scanner, and the check engine light should turn off if the issues have been resolved.
