Answer:		Your 1997 Honda Civic is equipped with an On-Board Diagnostics (OBD II). The OBD II system monitors all aspects of your Civic's emissions system and reports information to the OBDII computer. The data is processed and checked against the computer's pre-determined values for various inputs levels and performance patterns of your vehicle. If any problems are found the computer will determine whether to alert the driver or not. Setting the emission monitors requires driving your Honda at least 300 miles; consisting of everyday normal driving, stop and starts (like at red lights and traffic), ignition on and off several times a day with at least 15 minute causes in between (this allows the EVAP monitor to run), and freeway driving at least on three occasions for at least 15 minutes each at speeds above 30 mph. After these driving conditions are met and your Civic still fails the OBD II monitors portion of the smog check, we can only recommend the dealership conduct a diagnosis of the OBD II computer as to clues of why the monitors are not setting. Assuming no Check Engine light or Malfunction Indicator Lamp is illuminated, we have to suspect your vehicle's only problem is not enough drive time. posted by SmogTips Support
