How can my vehicle fail OBD II emission inspection?
Your vehicle can fail OBD II emission inspection 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 was lit, but went out without any action on your part, OBD II will still have a recorded fault. Your vehicle may pass or fail, depending on the inspection practices in your area.
- If you had recent service that required disconnecting the battery, OBD II diagnostic information may be incomplete and “not ready” for inspection. A vehicle that 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 – or was 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 Check Engine light, or if you had service that required disconnecting the battery, a period of driving is necessary to bring the OBD II system to “ready” for inspection. Two half-hour trips of mixed stop-and-go/highway driving are typically needed to allow OBD II to reach readiness. Your Volvo retailer can provide you with more information on planning a trip.
- Maintain your vehicle in accordance with your vehicle’s maintenance schedule.
