DESCRIPTION AND OPERATION (Continued)
The cooling system removes heat from various
The interface adapter assembly (IAA) controls the
electronic components. The coolant pump has a
operation of the electric coolant pump and the
centrifugal impeller design with a 12-volt permanent
electric radiator fan, based upon vehicle coolant
magnet motor. The pump is used to circulate the
temperature. The IAA receives the temperature
coolant through the DC/DC module,
information from the coolant temperature sensor,
motor/transaxle, and the traction inverter module
which is located near the coolant pump. The pump
(TIM). Because of the Electric Rangers unique
circulates coolant through the vehicle using a
systems, vehicle coolant is not used in the
combination of rubber hoses and metal tubing. The
heating/defrosting system.
IAA energizes the pump whenever the ignition key
is in the ON position and during traction battery
charging if the DC/DC module is charging the
auxiliary 12-volt battery. The electric fan is also
controlled by the IAA. If the coolant temperature
exceeds 40
°
C (104
°
F), the cooling fan runs at low
speed. If the coolant temperature rises above 45
°
C
(113
°
F), the cooling fan runs at high speed. The
IAA turns the cooling fan off when the coolant
temperature is less than 35
°
C (95
°
F). The IAA will
also activate the fan during vehicle charging if the
DC/DC module is charging the auxiliary battery.

DTC C1774 Coolant Temperature Sensor Out of
g
to
Range
— The interface adapter assembly (IAA) module
operates the radiator cooling fan based on
coolant temperature. The IAA module uses the
coolant temperature sensor to monitor the
coolant temperature. The normal range of the
coolant temperature sensor is between -40
°
C
(-40
°
F) and 150
°
C (302
°
F). If the coolant
temperature sensor is reading out of range, the
IAA module sets DTC C1774.
