To read codes on a 2002 Buick Rendezvous, you can use an OBD-II scanner. First, locate the OBD-II port under the dashboard near the steering column and connect the scanner. Turn the ignition to the "On" position without starting the engine, and then follow the scanner's instructions to retrieve the trouble codes. Alternatively, you can use the "key dance" method by turning the ignition key on and off multiple times to display the codes on the dashboard, although a scanner provides more detailed information.
