a code reader is just that it reads codes a scanner will read codes and will read readyness status of monitors. A code reader just pulls codes. a scanner pulls codes, stores freeze frame data and you can view live sensor data. the engine light may not be on but there may still be a codes stored in the computer. the code reader can still be used to check for codes that don't turn the light on.
