DESCRIPTION & OPERATION The fan control module is powered from fusible link No. 2. See Fig. 1
. The PCM
judges the required revolution speed of radiator fan motor and condenser fan motor
using input signals transmitted from the A/C switch, automatic compressor
controller, vehicle speed sensor and engine coolant temperature sensor. The PCM
activates the fan control module to drive the radiator fan motor and condenser fan
motor. COMPONENT LOCATIONS COMPONENT LOCATIONS Component

AUTO-CRUISE CONTROL SYSTEM DIAGNOSIS INTRODUCTION TO AUTO-CRUISE CONTROL SYSTEM DIAGNOSIS The auto-cruise control system allows driving without stepping on the accelerator
pedal by setting a random speed between 40 km/h (25 mph) and 170 km/h (106
mph). Problems in this system can be investigated by the following methods. Auto-cruise control system diagnostic trouble codes The auto-cruise control system consists of the powertrain control module (PCM),
control switches and sensors. The control switches and sensors monitor the state of
the vehicle. The PCM controls the throttle valve opening angle in the throttle body
in accordance with the in
put si
gnals from the switches and sensors. If the PCM

CIRCUIT OPERATION
The fan control module is powered from fusible link number 2. The PCM judges the required revolution speed of radiator fan motor and
condenser fan motor using the input signals transmitted from A/C switch,
automatic compressor controller, vehicle speed sensor and engine coolant
temperature sensor. The PCM activates the fan control module to drive the
radiator fan motor and condenser fan motor.
TECHNICAL DESCRIPTION
The cause could be a malfunction of the fan control module power supply or
ground circuit. The cause could also be a malfunction of the fan control module or the PCM.

TECHNICAL DESCRIPTION The fan controller has variable control of the radiator fan motor and the condenser
fan motor speeds using signals transmitted from the PCM. TROUBLESHOOTING HINTS NOTE: If the engine coolant temperature reaches 110°C (230°F) or
higher, the radiator fan control runs the radiator fan for up
to 5 minutes even after the ignition switch is turned to the
"LOCK" (OFF) position [the fan stops its rotation when the
engine coolant temperature decreases to 110°C (230° F) or
lower.]
