10 Maintenance and servicing
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.

Booking service and repairs
OBD II is part of your vehicle's computerized
engine management system. It stores diag-
nostic information about your vehicle's emis-
sion controls. It can light the Check Engine
light (MIL) if it detects an emission control
"fault." A "fault" is a component or system
that is not performing within an expected
range. A fault may be permanent or tempo-
rary. OBD II will store a message about any
fault.
Connected Service Booking (CSB) makes set-
ting up a time for service, maintenance and/or
repairs directly from the vehicle quick and
convenient.

How can I prepare for my next OBD II
emission inspection?
Prerequisites
•
The owner (primary driver) must have a
valid Volvo ID. See Volvo ID (p. 21) for
additional information.
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.
The vehicle must be connected to the
•
Internet using a paired Bluetooth®
cell
phone. See your Sensus Infotainment
supplement for information on pairing a
cell phone. On models equipped with
Volvo On Call (VOC)*, you can connect to
the Internet using your separate VOC

Emission inspection readiness
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.
How do states use OBD II for emission
inspections?
Many states connect a computer directly to a
vehicle's OBD II system. The inspector can
then read "faults." In some states, this type of
inspection has replaced the tailpipe emission
test.
