Fuel and Refueling
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days. If
the vehicle is not ready for I/M testing, you
can perform the following driving cycle
consisting of mixed city and highway
driving:
15 minutes of steady driving on an
expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
Allow your vehicle to sit for at least eight
hours with the ignition off. Then, start the
vehicle and complete the above driving
cycle. The vehicle must warm up to its
normal operating temperature. Once
started, do not turn off the vehicle until the
above driving cycle is complete. If the
vehicle is still not ready for I/M testing, you
need to repeat the above driving cycle.
