Working On Your Car - Volvo S60 Owner's Manual

2006 Volvo S60
tailpipe emission test.
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. A half-hour trip of mixed stop-and-go/ highway driving is 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.
