  1. Drive Cycle Pattern
  2. Drive Cycle Procedures
  3. Drive Cycle Video without EVAP
  4. Drive Cycle EVAP Video

1. This pattern should be used for most NISSAN/INFINITI vehicles between 1998 - 2003.  During these years, the EVAP system tested under pressure in Steps 5 & 6.

2. The steps listed pertain to the pattern shown above. NOTE: Depending on the startup engine temperature, vehicle speed, and engine load, these steps can run out of order.

3. This video was captured while performing this drive cycle on a dynamometer.  The factory scan tool at that time displayed the inner workings of the Engine Control Module (ECM).  Pattern 1 does not show Steps 5 & 6 for the EVAP portion of the drive cycle. These steps will be shown in the following video.

4. This video shows NISSAN Pattern 1 Step 5.  Step 6 is only required if the Fuel Temp Sensor does not rise a minimum of 2 degrees Celsius (4 degrees F).  Focus on the Fuel Tank Temperature, Purge VOL, VAC Cut, and Vent solenoids. The OE side of the scan tool will have to be accessed to see these PIDs.  NOTE: The vent solenoid might not be displayed when using an aftermarket scan tool.
