On-Board Diagnostics Inspection I Tips For Smooth Testing

Tips for a successful test:

• Please bring your vehicle to an inspection facility as soon as possible after receiving your test notice.  If your vehicle is rejected or fails the inspection, this will provide ample time to repair the vehicle and have it re-inspected prior to license plate expiration.
• Test stations are closed on Sundays and state holidays.  The busiest testing day is Monday.

     Prior To Arriving at the Test Station:

• Please bring your vehicle's test notice with you to the test station. 
• Make sure the vehicle brought in for testing matches the vehicle identified on the test notice.
• If your 1996 or newer OBD-equipped vehicle has a covered or otherwise obstructed diagnostic link connector (DLC), please open or remove the cover (consult owner's manual for location and instructions), or remove the obstruction prior to arriving at the test station.
• If your 1996 or newer OBD-equipped vehicle has recently been serviced, or if the battery has been disconnected, please drive the vehicle for several days before bringing it in for inspection.
• Ensure your vehicle is safe to operate. Your vehicle may be rejected if the test cannot be safely conducted.

     At the Test Station:

• When you arrive, leave the engine running unless directed otherwise.
• Inform the inspector when entering the test lane if the license plate number on the vehicle is different from the number on your test notice
