To retrieve fault codes from a 1993 Buick Roadmaster, you can use the On-Board Diagnostics (OBD) system by connecting a scan tool to the diagnostic port, usually located under the dashboard near the steering column. Alternatively, you can perform a key-on, engine-off procedure by turning the ignition key to the "ON" position three times (without starting the engine) to trigger the "Check Engine" light, which will flash a sequence of codes. Count the flashes to interpret the fault codes, referring to the vehicle’s service manual for code definitions.
