With Consult-II

WARNING: This page is about a different car, the 2007 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition switch OFF, wait at least 10 seconds and then turn ON.
  2. Check "COOLAN TEMP/S" in "DATA MONITOR" mode with CONSULT-II.

    Confirm "COOLAN TEMP/S" value is within the range listed below.

    COOLAN TEMP/S: Less than 40°C (104°F) 

    If the value is out of range, park the vehicle in a cool place and allow the engine temperature to stabilize. Do not attempt to lower the engine coolant temperature with a fan or means other than ambient air. Doing so may produce an inaccurate diagnostic result.

  3. Start engine and let it idle monitoring "COOLAN TEMP/S" value. When the "COOLAN TEMP/S" value reaches 70°C (158°F), immediately go to the next step.
