•
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 diag-
nostic 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.
