Radiator Cooling Fans: Notes

The ECM controls radiator cooling fan(s) based on vehicle speed, engine coolant temperature and A/C switch position. The following tables list correct cooling fan operation based on certain conditions. See appropriate A/C SWITCH ON or A/C SWITCH OFF table. If cooling fan does not operate as specified, see appropriate RADIATOR (COOLING) FAN CONTROL TEST. Tests are not available for Pathfinder.
