2018 Chevrolet Cruze OBD2 Scanner

A code identifies a detected concern or circuit, not necessarily one failed component. Use the code with the vehicle's diagnostic procedure and other test results before deciding what to replace.

Coverage varies by tool and vehicle. The A-Premium PD200 listing names engine, ABS, SRS and transmission systems; a basic code reader may offer a different range. Confirm support for the specific model and vehicle.

Manufacturer-specific systems and functions differ from basic OBD information. A PD100G listing identifies Chevrolet, GMC, Buick and Cadillac, while another PD100 version names Audi and Volkswagen group brands. Check the required vehicle and function coverage.

Clearing a code removes stored diagnostic information; it does not correct the condition that produced it. Save the relevant information and diagnose or repair the cause before deciding whether to clear codes.

The vehicle has not completed that monitor's diagnostic check under the required operating conditions. A not-ready status alone does not establish that a part has failed; readiness may be reset when codes are cleared.
