How do states use OBD II for emission
inspections?
Many states connect a computer directly to a vehicle's OBD II system. The inspector canthen read "faults." In some states, this type ofinspection has replaced the tailpipe emissiontest.
How can my vehicle fail OBD II emission inspection?
Your vehicle can fail OBD II emission inspec-tion for any of the following reasons.
• If your Check Engine (MIL) light is lit, your vehicle may fail inspection.
• If your vehicle's Check Engine light waslit, but went out without any action onyour part, OBD II will still have a recordedfault. Your vehicle may pass or fail,depending on the inspection practices inyour area.
• If you had recent service that requireddisconnecting the battery, OBD II diag-nostic information may be incompleteand "not ready" for inspection. A vehiclethat is not ready may fail inspection.
How can I prepare for my next OBD II
emission inspection?
• If your Check Engine (MIL) light is lit – orwas lit but went out without service, have your vehicle diagnosed and, if necessary,serviced by a qualified Volvo technician.
• If you recently had service for a lit CheckEngine light, or if you had service thatrequired disconnecting the battery, aperiod of driving is necessary to bring theOBD II system to "ready" for inspection.A half-hour trip of mixed stop-and-go/highway driving is typically needed toallow OBD II to reach readiness. YourVolvo retailer can provide you with moreinformation on planning a trip.
• Maintain your vehicle in accordance withyour vehicle's maintenance schedule.
