DTC Confirmation Test (Using Generic Scan Tool)

WARNING: This page is about a different car, the 2002 Infiniti Q45. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Before performing test, ensure fuel tank level is 1/4-3/4, ambient temperature is 32-86°F (0-32°C) and EVAP-CPVCV hoses are installed correctly.
  1. Start engine. Drive vehicle according to specified driving pattern to set System Readiness Test (SRT) codes. See SYSTEM READINESS TEST  under SELF-DIAGNOSTIC SYSTEM. Stop vehicle and go to next step.
  2. Select MODE 1 on scan tool and check SRT status of EVAP system. If EVAP system SRT is complete, system is okay at this time. If EVAP system SRT is incomplete, turn ignition off, wait at least 10 seconds and go to next step.
    3. NOTE: It is not necessary to allow engine to cool before driving vehicle.
  3. Perform driving pattern again. Select MODE 3 on scan tool. If DTC P0440, P0455, P1440 or P1447 is set, perform appropriate diagnostic procedure. If DTC P0440, P0455 P1440 or P1447 is not set, go to step  2.
