Cooling Fan Relay Operation
The ECM controls cooling fan relays in the IPDM E/R through CAN communication line.
COMPONENT DESCRIPTION
Cooling Fan Motor
The cooling fan operates at each speed when the current flows in the cooling fan motor as follows.
The cooling fan operates at low (LOW) speed when cooling fan motors-1 and -2 are circuited in series under
middle speed condition.
CONSULT-II Reference Value in Data Monitor ModeBBS005G8
Specification data are reference values.
On Board Diagnosis LogicBBS005G9
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise. When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction
is indicated.
This self-diagnosis has the one trip detection logic.
