~ This is the drive cycle that must be performed if the OBD system comes up as "not ready"
during a smog check. ~
. To ensure all ECM Self Test requirements are met, drive the ENTIRE pattern whenever
any SRT items indicate "INCOMPLETE."
. Some vehicles require that sections of the Drive Pattern be driven two times to satisfy
the self diagnosis two trip logic. This requirement is called out in the Nissan SRT
System Chart and by a double line in the actual drive patterns.
For vehicles that require two trips, the pre-check engine coolant temperature must be
met (coolant temp must be below 158 degrees
Fahrenheit ) before beginning the second trip.
