The following may correct an
emission control system
malfunction:
If fuel has been added to the
vehicle using the capless funnel
adapter, make sure the capless
funnel adapter is removed. See
Filling the Tank with a Portable
Gas Can under Filling the Tank
on page 9-53. The diagnostic
system can detect if the adapter
has been left installed in the
vehicle, allowing fuel to
evaporate into the atmosphere.
A few driving trips with the
adapter removed should turn off
the light.
Check that good quality fuel is
used. Poor fuel quality causes
the engine not to run as
efficiently as designed and may
cause stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these conditions
occurs, change the fuel brand used.
It may require at least one full tank
of the proper fuel to turn the light off.
See Fuel on page 9-51.
If none of the above have made the
light turn off, your dealer can check
the vehicle. The dealer has the
proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.
Emissions Inspection and
Maintenance Programs
Depending on where you live, your
vehicle may be required to
participate in an emission control
system inspection and maintenance
program. For the inspection, the
emission system test equipment will
likely connect to the vehicle's Data
Link Connector (DLC).
Instruments and Controls
The DLC is under the instrument
panel near the hood release. See
your dealer if assistance is needed.
The vehicle may not pass
inspection if:
The malfunction indicator lamp is
on with the engine running, or if
the vehicle is placed in Service
Only Mode and the malfunction
indicator lamp does not come
on. See your dealer for
assistance in verifying proper
operation of the malfunction
indicator lamp.
The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed. The
vehicle would be considered not
ready for inspection. This can
