If none of the above have made the light turn off, your
dealer/retailer can check the vehicle. The dealer/retailer
has the proper test equipment and diagnostic tools to
fix any mechanical or electrical problems that might
have developed.
Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
•
The vehicle will not pass this inspection if the check
engine light is on with the engine running.
To perform a check engine light bulb check with the
keyless ignition, make sure the transmitter fob is in
the passenger compartment. See Ignition Positions
on page 2-23. Press the bottom of the Acc. button
on the instrument panel and hold the button down
for five seconds. The instrument panel, including the
check engine light, will light up and the ignition will be
on, but the engine will not start — press the bottom of
the Acc. button only briefly, less than five seconds,
the accessory power mode will be turned on, but not
the ignition. After the bulb check, press and release
the Acc. button again to turn the ignition off and avoid
draining the vehicle’s battery.
•
The vehicle will not pass this inspection if the OBD II
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen
if the battery has recently been replaced or if the
battery has run down. The diagnostic system is
designed to evaluate 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 for
lack of OBD II system readiness, your dealer/retailer
can prepare the vehicle for inspection.
