Emissions Inspection and
Maintenance Programs
Some state/provincial and
local governments may have
programs to inspect the on-vehicle
emission control equipment.
For the inspection, the emission
system test equipment is connected
to the vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. 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 light does not come on when
the ignition is turned to ON/RUN
while the engine is off.
.The critical emission control
systems have not been
completely diagnosed by
the system. This can happen
if the battery has recently
been replaced or if the battery
has run down. The diagnostic
system evaluates critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection, your dealer can
prepare the vehicle for
inspection.
Brake System Warning
Light
The vehicle brake system
consists of two hydraulic circuits.
If one circuit is not working, the
remaining circuit can still work to
stop the vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a brake problem. Have your brake
system inspected right away.
EnglishMetric
If the vehicle has antilock brakes,
this light should come on when the
vehicle is placed in START. If it does
not, have the vehicle serviced by
your dealer.
